Title: Trains without retention tanks spray human effluent over railway trackside workers
Post by: plymothian on April 14, 2009, 10:24:55
Was pondering this on my journey home last night, is such a command really still necessary in this day and age?

Because the HSTs were designed and built in the 1970s when train toilets had dumped straight on the ground since forever. Bogs with retention tanks ("controlled emission toilets" in current jargon) are a relatively recent innovation, and it would be hugely expensive to retro-fit all of today's stock with them given their expected remaining service life. Rest assured the IEP will surely have them!

As an aside, FGW have an ingenious trial underway on at least one vehicle (when I used it is was labelled and formed as a "coach B") in which the toilet flush button is rendered inactive whenever the central door locking is disengaged and remains so for 20 seconds after the doors are locked. This is indicated in the actual khazi by a blue light which is illuminated when you can't flush.

All new trains have retention toilets.  Old trains do not. 

You could argue that announcements about not flushing in stations are more neccessary nowadays on non-retention trains because some passengers will assume that all trains have retention toilets.

Not impossible to retrofit retention tanks to some trains, as seen with SWT's recent 158s and 159 overhauls.  But in FGW's case, they'd need to also add the infrastructure to deal with their 158s in the Bristol area - waiting for their turn to outberth at Fratton wouldn't be very practical... :o

That's definitely true, but the size of SWT's 158 and 159 fleet is pretty modest compared to the number of vehicles FGW would have to retro-fit to find themselves in the same position. To the best of my knowledge only the 165, 166 and sleeper fleets have retention tanks. I can't see it being economic to fit tanks to the whole 15x, 14x and HST fleets any time soon, not to mention the necessary "facilities" - sorry! - at Landore/St Phillips Marsh/Old Oak etc etc.

retention toilets will come in time anyway.  Money would be better spent elseware than trying to speed this up.

I read something many years ago suggesting that if toilets didn't empty onto the track, we could replace ballast with concrete paving to which the tracks were clipped and that this would be cheaper to maintain.  However, I note that HS1 has ballast and retention toilets so probably a "Tomorrow's World" vision of the future.

AFAIK, two sets modded and been running around since beginning of this year on a 6 month trial at the moment to evaluate effectiveness and reliability.

Hopefully, this trial will not turn out to be just a flash in the pan, or get bogged down, but will lead to FGW, flushed with success, installing it on all of their trains?

I must say, the specification for that particular trial did appear rather flawed to me:

Quote

In my experience, just because the CDL is engaged doesn't necessarily mean the train is going to leave the platform within 20 seconds.  Indeed, even if the train does pull away fairly promptly, the rear (if you'll pardon the expression) carriages will probably still be opposite the platform, even if the front of the train is well beyond it?  ::)

Doesn't sound like it'll be perfect, I admit, but has to be a big improvement on the current situation. Flushing the lav at speed is less of an issue because the "effluent" gets caught up in the 125 mph slipstream and is mostly splattered over the running gear of the train itself rather than falling straight on the ground as happens when the train is stationary.

I have first-hand experience of a "near miss" from an illiterate bog user - they flushed the loo when I was coupling a locomotive onto the train and their little offering (yes, it was solid  >:() missed me by inches. I don't suppose they expected to be bawled at by an angry shunter because they emerged from the khazi looking a little shell shocked.

i remember a 143 i was working had fitters attention on plat 1 at btm,they were doing something underneath when a passenger flushed the lav missing them by inches.upon leaving the toilet the passenger found it funny until the fitter had some choice words.

Indeed. A minute would be a more appropriate delay - twenty seconds and the train will only have moved a couple of feet even with the promptest of dispatching!

What do folks think of the revolting mess underneath the SLE's and SLEP's at Paddington (that's the night sleepers)? There used to be brick channels that could be hosed down but now there's ballast covered by plastic sheeting. The net result is slowly evaporating pools of liquid, solidus, papier mache etc between the platforms, perfuming Brunel's masterpiece and appropriately introducing Heathrow Express customers to the Country where they have just landed. Stations are probably exempt from the Public Health Acts otherwise the Local Authority could close the lot down.

NR, FGW and all the King's horses could do better than this.

the plastic sheeting is supposed to make cleaning easier.  It is changed sometimes although perhaps not enough. 

I have never used the FGW sleeper but have used the Scotrail one many times.  I am sure that the Scottish sleeper coaches do have retention toilets and I am surpised that the FGW ones do not. 

Whilst I wouldn't favour retrofitting tanks to all older stock the sleeper trains could probably be justified as an exception - afterall you are allowed to baord at Paddington an hour or so before departure.  Supposing you board at 10:30 and want to use the facilities before going to bed.  Are you supposed to leave your compartment and find a station toilet or stay awake until the train has left paddington at 11:45 pm?  If so the train is effectively without a toilet during the times demand for one is likely to be highest

The sleepers do have retention tanks.  The mess comes from people who use the HST toilets whilst the train is standing in the platform.

Let's get it clear, the sleeping cars have retention tanks, the Day Cars of the sleeper train DO NOT.

The class 159's were modified 158's (and modified before they ever entered service) and 159's have retention tanks, the 158 do not.

In my experience, very little use of the toilets in HST's is made in Paddington Station, certainly for No. 2's. Most customers are either fighting to get a seat or lining up to get off.

Thus if the few Mk3a loco hauled cars marshalled with the sleepers were given retention tanks, the station sewage problem would be almost gone.

In this case it's the Railway that has the dirty habits rather than its customers.

Swindon's not great either. If the experiment is rolled out to the rest of the HST stock this would eliminate the problem here (except the bay), also Chippenham (almost, before Graham corrects me), and several other stations would see a significant reduction at some if not all of their patforms.

I don't know how much it will cost, but presumably there's a trade off in how long the stock will continue in use.  Given the HSTs have just been refurbed it might still be viable.

I noticed that the other day that a SWT class 158 had retetion tanks, I also became aware the other day at Leeds that when retention tank are full they overflow onto the tracks. Ok it appered to just be liquid but it's still foul liquid.

A verbatim extract from Hansard 14/02:

Mr Jenkin: To ask the Secretary of State for
Transport what estimate his Department has made of
the volume of sewage discharged onto railway tracks in
the latest period for which figures are available.

While the discharge of toilets directly onto the tracks is potentially unpleasant, I can't help thinking that our elected representatives should really be applying themselves to resolving some of the more fundamental problems currently blighting our railways.

(NB. The SoS's answer was 'no idea - ask ATOC')

While the discharge of toilets directly onto the tracks is potentially unpleasant,

Extremely unpleasant if you are a track-worker standing in the cess when a discharging toilet on a HST goes by, particularly if on the outside of a curve.

I remember reading somewhere about a photter who'd also been subject to a short sharp shower of sh1t whilst standing next to an occupation crossing gate on a max speed section of the ECML, again on the outside of a curve. I think it happened to him more than once. I think I'd've learnt after the first shower not to stand so close to the line when a HST was approaching!


Title: Re: Trains without retention tanks spray human effluent over railway trackside workers
Post by: inspector_blakey on February 15, 2011, 21:03:44
The principal issue on the ECML I believe was with mark IV trains, and not HSTs. Ironically, despite having controlled emission toilets, these were (still are...?) emitting a fine spray of effluent when the tanks were full as they entered certain superelevated curves. GNER/NXEC (forget who it was at the time) promised that they would improve facilities for discharging the tanks at depots to alleviate the problem.

For some reason the RMT chose to make an enormous song and dance about this whilst more or less ignoring all the other direct emission bogs whizzing around the network. In fact HST lavs don't generally discharge much laterally at speed, it tends to end up in the four-foot or end up stuck to the underframe of the vehicle. This can of course make life unpleasant for shunting and depot staff but it's a different problem from it forming an aerosol and spraying around the lineside.

For some reason the RMT chose to make an enormous song and dance about this whilst more or less ignoring all the other direct emission bogs whizzing around the network.

AFAIUI, the RMT made a fuss about the Mark IV toilets because they produced more of a problem with aerosolised effluent rather than other toilets which generally dump their load straight onto the track. 

I think that the problem arrose after the Mk VI refurb which placed a controlled emmissions toilet orginally designed for staff use only at the disposal of the public.  The extra load meant that the toilet couldn't cope without regular emptying (and GNER went back on a promise to install emptying points at their depots to allow this to happen).  The key difference was that toilets designed to dump onto the track do so fairly safely, whereas overflowing CET which are not designed to dump onto the track do it as a dangerous fine mist.

I used to work in an HIV lab and received training on how do handle the virus safely.  These bugs (and similar things like Hepatitus) are farily safe if you are sensible about gloves and hand washing etc.  But I has told that the think you absolutely didn;t want to do was breath in an aerosol containing virus (elborate precaution were taken ert centrifuges and thinsg like that that might produce a viral mist. 

I don;t usually take the RMTs side, but personally, I would strike over this isue.  GNER were lucky IMHO to not get done under H&S law over this.

HST toilets are not fitted with retention tanks. Any unpleasant sights are there because passengers have not heeded the sign in the cubicle to not flush the toilet when the train is in a station.

I read in a magazine recently that in the future HSTs might be fitted with an interlock so you couldn't flush them when the train was in a station.

Two problems I can see - it's something else to go wrong. Secondly if someone cannot flush it they are likely to walk away and leave it for the next person.

There was a "flush inhibit modification" trialled by FGW a while ago. When the secondary locking for the external doors was unlocked (as in a station) and for a brief time delay after the doors were locked to allow the train to pull clear, the flush was inactivated.

I assume it wasn't that successful because I only ever travelled on one set that had it fitted and have not seen any evidence of the modification being "rolled out".

Consequently I needed to avail myself of the <ahem> facilities as we trundled to Filton Abbey Wood.

Noticed this sign in the toilet:

A few years ago Network Rail said they were going to start charging TOC's extra for dealing with the problems of items flushed onto the track at terminal stations.  So FGW started work on a system that would stop the flush working while the train was at a station.

Then the ORR said that Network Rail were not allowed to charge extra so the development of the system was stopped.  I believe one set of coaches was modified for the prototype.

I wonder (but not seriously) if the "blue buttons" are linked to the central locking mechanism so you can't flush the loos when the doors are unlocked. Not sure how this would work in a station such as Theale or Thatcham when only a certain number of doors are opened.

What a thought provoking conversation for a Sunday morning!

Train toilet flushing hits Brunel bridge workers

Workers repairing Brunel^s twin span bridge in Plymouth have called on train passengers to resist the call of nature as they pass over the historic structure.

Contract workers from scaffolding and painting specialists Taziker Industrial working below the bridge deck are having to dodge sudden toilet flush bursts onto the tracks.

Project manager Peter Cook said: ^We haven^t had a direct hit but there have been several near misses.

^Usually this would not be a problem, but the older trains are running on a wooden bridge deck, which doesn^t protect from toilet waste.^

First Great Western confirmed that some of its older rolling stock still dumped toilet waste on the tracks and it had asked passengers to refrain from using the toilets as they passed over the historic bridge.

One passenger told the Enquirer: ^The guard made a special announcement on the train^s tannoy as we came up to the Tamar River valley.

^I thought he was going to tell us we were about to pass over the iconic bridge, but instead he asked passengers to avoid using the toilets.^

^I suppose it^s a polite way of saying please mind the crap.^

TI won the ^10m job to restore the 1859 steel bridge between Devon and Cornwall last June.

In all, over 100t of new steelwork will be added, 205 original Brunel cross girders will be repaired, 40 diagonal bracings will be strengthened, and 1,800 individual steelwork repairs will be completed.

Up to 50,000 bolts have been purpose-designed to look like the existing rivets.

TI workers will also apply 35,000l of paint in four coats: a zinc primer, a strike coat all around the rivets and edges to build up the minimum thickness, a glass flake epoxy intermediate layer, and finally a Goose Grey polyurethane finish coat to match the original colour of the bridge.

The system is similar to that used on the Forth Bridge, but with a bit more elasticity because this bridge has more movement.

By that they mean, all except one FGW train in each direction over the bridge have toilets that flush directly on to the track. Only the sleeper, even then only in the berth carriages, and the four XC voyagers a day in each direction do have retention tanks.

First Great Western has said its train managers are issuing pleas to passengers to avoid flushing toilets when travelling over the historic twin-span Royal Albert Bridge.

Plymouth TM today made NO mention of this today, however the Penzance TM later on did. Made us aware of exactly what work was taking place too. 

Has anyone working on the bridge been splatted yet?
Also can anyone confirm if and when trains have to tank their waste by?

No retrofitting requirement that I can find. 

A couple of RSSB reports that Google found simply note that all relevant rollng stock is expected to be out of service by 'about 2020'.

I boarded the 1207 Bristol Parkway to Swansea service this past Wednesday and because of the delay due to problems in the Severn Tunnel I managed to down two cans of Carlsberg before we'd actually set off. Consequently I needed to avail myself of the <ahem> facilities as we trundled to Filton Abbey Wood.

Noticed this sign in the toilet:

Is this a new thing or have I just not been observant in the past when micturating onboard HSTs?

Noticed this yesterday while on an HST - I assume the experiment didn't work and it wasn't extended to other sets.

I think there are 2 sets with it installed on.  It's not linked to the CDL, I think it's linked to the speed of the train... Although there is an over-ride button to allow flushing at anytime in the TM office.

From the BBC (http://www.bbc.co.uk/news/uk-politics-24925280):

Quote
Train companies must stop dumping human waste from toilets on railway tracks, a transport minister has said.

Lady Kramer branded the practice "utterly disgusting" and called on the industry to take action.

The RMT rail union is also demanding action, saying it is a potential health hazard for track workers.

The train companies said carriages without toilet tanks were being phased out and it was not an issue raised by passengers or workers.

Modern trains are fitted with toilet tanks, which are pumped out at the depot when they become full.

'Terrible'

But older rolling stock, which is still running on many of Britain's busiest routes, still discharges sewage directly on to the track.

Former Conservative minister Baroness Wilcox raised the issue as the House of Lords debated the 20th anniversary of rail privatisation.

"I am very sorry to see that still we have raw sewage going out on to the lines," she told peers.

"It is a terrible thing to see after all these years since November 5, 1993 that we should still be doing that."

She asked Lady Kramer: "Before we rush forward to HS2, which I am looking forward to enormously, I would like to urge you to think about the men working on the lines and working in the stations who are having to deal with this excrement."

The Lib Dem minister replied: "The comments you make totally resonate. This is just utterly disgusting and I think it does speak to the fact that customer service has not always been at the centre of railways because customers I think are very concerned about this issue."

She said InterCity 125 trains would be replaced from 2017 by new models which would solve the problem.

'Protective clothing'

But she added: "It is a tougher issue on the local diesel trains which are gradually going out of service and we could indeed use some help from the industry in trying to tackle that problem."

The RMT rail union claims parts of the rail network, such as stretches of the the East Coast Mainline, are "like an open sewer" and it was a frequent source of complaints from workers.

RMT General Secretary Bob Crow said: "It really is a shocking indictment on the state of our railways 20 years after privatisation, and with hundreds of millions of pounds a year being creamed off in private profits, that raw sewage is still being dumped on the tracks up and down the UK.

"Not only is it a filthy way of disposing of effluent, but it also poses real health risks and dangers for RMT members out there working on the tracks.

"It should be stopped and the train companies should be the ones who pay the price for upgrading the trains and employing staff to empty the tanks."

The Rail Delivery Group, which represents the train companies and Network Rail, said the issue did not come up in a bi-annual national passenger survey and "it is not raised as an issue by staff".

A spokesperson said: "The majority of rail carriages that have toilets are fitted with tanks and the number of older carriages which are not will fall further in the next few years as new InterCity trains are introduced.

"The industry is always listening to customers and has spent millions of pounds on installing and improving passenger toilet facilities.

"Train companies and Network Rail also take their duty of care towards staff very seriously and ensure that depot and trackside teams are given the right training, equipment and protective clothing for their roles."

I think it's also a shocking indictment that in the twenty years before privatisation, when hundreds of millions of pounds were not being creamed off in private profits, that nothing was done then to stop raw sewage being dumped (if you'll pardon the expression) on the tracks ...  :o ::)

I have mixed views on all this...

Having trains with retention tanks to hold the toilet waste is one thing... But making sure the TOC empties them is quite another.

I believe that Class 357 (c2c) and Class 377 (Southern/FCC/Southeastern) units close the toilets once the tank reaches 75% Capacity... Which is considerably less than ideal if one had a full bladder and would like to add to that remaining 25% space...

I believe Voyagers do something similar. It is not unusual to board an XC Service at Bristol Temple Meads and find at least one toilet out of service... >:(

Agree retention tanks on short trains with few toilets on long journies are a problem particularly with DaFTs obssession with cramming as many seats in each carriage as possible. How many loos doies an IEP have for 600+? Maybe the answer is  more carriages per train with more toilets.

Or if we are going to have short trains with few toilets on long journies maybe emptying facilities on route at say Birmingham, Bristol Cardiff Manchester Preston/ Carlise Newcastle Edingburgh. After all they used to water trains at such places. Be done in 5 minutes station stop.

It's quite a clean operation provided the hose is securly coupled just like pumping out a narrow boat's tank.

Not far off, it's actually 80% full. The clue is that outside of the toilet, the WC light starts flashing. 357 units only have one toilet, but on 375 and 377 units there are two toilets, and the small toilet (i.e. not the universal one) does not lock itself - that remains open, although of course a member of staff could lock it shut if it started overflowing!

As for the universal toilet, it is possible for a member of staff to open it up for further use when full, although it locks again after each further use, so only really best for situations of urgent need.

Turbos actually have a gauge fitted below the toilet on the outside of the carriage to indicate how full the toilet waste tank is. One light means 50% full, two lights mean 80% full. Although it is so low down and covered in dust/dirt seeing it in practice is difficult! With the fitment of a universal toilet as part of the Turbo refurbishment, I expect we'll see a similar feature introduced where the door locks itself.

The taps and the hand-dryers in them just seem to be generally quite poor too. The tap is only ever giving out a light spray of water at best and the hand-dryers are very feeble, it would take you an age to actually dry your hands using them. Could do with the hand-towels fitted to most of the FGW fleet.

The sinks are badly designed.  As soon as you put your hands under the tap, the water bounces off to anywhere except the sink.

That's why there's often a wet floor in a Turbo toilet.

Cambridge rail worker's health fears over excrement spray

Rail workers are being sprayed by human urine and faeces from passing trains, putting their health at risk.

A Network Rail worker said staff were "genuinely concerned" about excrement, urine and sanitary towels on the tracks.

Network Rail accepted that train toilets which emptied on the track were "outdated and unpleasant" for track workers.

Greater Anglia said it was hoping to phase out toilets which dump waste.

The man who works across the East Anglia region said: "A train would be coming and we'd stand back the recommended distance.

"It's not unusual to feel a spray, a kind of mist in the air. That's bad enough, but then you walk back to where you've been working on the tracks there's [faeces] everywhere."

'Effort needed'

Passenger waste is discharged from trains not fitted with retention tanks.

The majority of trains running through Cambridge station are operated by Greater Anglia, First Capital Connect and CrossCountry.

More than half of Greater Anglia's trains in the Cambridge area do not have retention tanks. The other two operators' trains do not discharge on to the track.

"We'd like to see them replaced or modified, but this requires effort from across the industry and funding," said a Network Rail spokesman.

The Department for Transport said the government recognised "this is a very unpleasant experience for railway workers and the public" and was "working closely" with Greater Anglia on a fleet upgrade.

What's interesting is that I've read in Today's Railways UK (Jan 2014 issue) that the Greater Anglia Class 321s currently being refurbished at the behest of the Eversholt leasing company keep one of their non-retention toilets, while the new universal access toilet has a retention tank. The purpose of the refurbishment is to keep the units running for a further 15 years.  This seems to be a long phase out.

I don't think the GA 321 fleet in general are being refurbished yet.  As I understand the current situation, a single demonstrator has been produced by the ROSCO, but a decision on production has not yet been made - that's why the demonstrator has two different interiors, metro at one end and suburban at the other.   I wonder if it's because fitting a retention tank on the existing does not really need to be 'demonstrated', but it is known it could be fitted if a decision was made.  Also, if they are refitted to 'metro' standards, they may remove the toilets completely anyway...

Sewage dumped on tracks by trains is a 'health risk'

Train companies have been accused of putting passengers' health at risk by dumping toilet waste on the tracks at some of London's mainline stations.

Modern trains are fitted with toilet tanks, which are pumped out at the depot when they become full, but older rolling stock does not have such a facility.

Unions say it is a health risk and companies should fit older trains with the tanks. The firms say the number of trains where this happens is decreasing.

BBC London's Transport Correspondent Tom Edwards spoke to Bob Crow, from the Rail, Maritime and Transport Workers' Union, and Seb Gordon, from the Rail Delivery Group.
http://www.bbc.co.uk/news/uk-england-london-26453915

This is, according to Bob Crow, not a Victorian practice, but a prehistoric one. Those pesky cavemen. Building trains without retention tanks.  ::)

The only reason the toilets block far too easily is because passengers flush all manners if things down them!

Train boss on flush menace: 'You learn to close your mouth'

Network Rail’s boss has experienced the horror of the train flush menace first-hand.

Mark Carne, chief executive of the Swindon-based organisation, told the Guardian: “You quickly learn to turn your back and close your mouth when you’re trackside and a train is passing. As I know first-hand.”

His comments came as rail firms prepare for a ban on trains flushing their toilets directly onto the tracks.

By the end of the decade, all rail franchise holders must operate trains with retention tanks. Rather than emptying their pans onto the tracks, as often happens now, trains will have to hold onto this waste water until it can be emptied at rail depots.

Network Rail’s Mark Carne spoke to the Guardian at Swindon station. “It’s disgusting,” he said of the evidence of a recently flushed toilet trip visible on the tracks. “I’ve been out there with the track workers and you see it coming, like a plume of steam. It’s totally unacceptable and I’m pleased we’ve got government agreement.”

A Network Rail spokesperson added that the improvements were possible following track improvement work: “As part of our Railway Upgrade Plan we have improved infrastructure across the route which allows new trains to run which do not dispose of waste onto the track like some of the older fleet,” he said. “Further planned route modernisation means fewer and fewer trains which dispose of waste onto the track will run on the railway.”

The RMT union has campaigned for an end to the practice of flushing toilets directly onto the tracks – which it says leaves its members “sprayed with human sewage”.

A spokesman said: “We want to see a firm schedule that forces the train operating companies to stop this foul and disgusting practice, which leaves our members out on the railways regularly sprayed with human sewage. We’re not interested in half-hearted pledges. We want cast-iron guarantees.”

Great Western Railway said that their new high-speed trains boast toilets with retention tanks. The new trains will start replacing the old Intercity fleet on the London to Bristol line from the end of this year.

This topic reminds me of an incident from India about eight years ago. A woman gave birth in a train toilet – and the baby fell through the toilet, which like some train loos you can still see in parts of Europe was just a hole in the floor, on to the track. Amazingly and luckily, the baby, a girl, survived and was found and reunited with the mother. Many people took this as a sign that the baby was blessed with good luck by the gods, and her parents were inundated with others of future marriage for their daughter. Sounds unlikely, but genuinely happened.

My Confession:

Sometime about 50 years ago I happened to be on a train with a schoolmate, which, unusually had toilets on it, and, having seen the hole in the floor type pan that it was, we put one end of the toilet roll down the pan just as we were arriving at Selhurst, to see what would happen, we were delighted to find that, once the train moved on, the track had a continuous strip of toilet paper from one end of the platform to the other.
I have matured a little since then.

Just 5 short years ago, whilst undertaking a Trans-Mongolia trip from St Petersburg to Beijing, I was similarly curious. I was in the last coach, which had a large picture window in the locked corridor door next to the very basic toilet facility. So, somewhere in northern Mongolia could be seen a long white paper trail leading away from the train.  Thankfully, the border guards had departed the train by this stage  ;D

There is one rail journey in southeast Poland, from Przemyśl to Ustrzyki Dolny, that makes a large loop through what is now Ukrainian territory. I'm not sure what the procedure is now but back in the 1980s, when Ukraine was part of the Soviet Union, it was treated as a local journey because both ends were in Poland so no passports etc were required. Soviet border guards would board the train, which then drove without stopping between those two stations. Except on one occasion when some Solidarity activists dropped pamphlets through the toilet-hole onto the track, obviously hoping they would be blown into nearby villages and spread knowledge of and support for the movement on the other side of the border. It didn't quite work out like that. The guards made the driver stop the train and it stood there, doors and windows locked, obviously, till all the leaflets had been picked up.

Spoiler for disgusting content - apologies!

I watched this episode last night and was surprised/disgusted that apparently the trains dont have a holding tank for human waste (is it just HSTs?) so if you use the facilities in the station it just empties on to the track.  Is this correct?  But why is there no smell?  The waste is cleaned up only every 3 months in the station, but what happens on the tracks outside - it must be left to decompose naturally?

Apologies again, but hard to belive my understanding is correct!

Older train such as the HST still discharge directly on the track - that's why there's a sign in the loo saying "do not flush while the train is standing in the station".   Newer trains have holding tanks, and I believe tanks are being retro-fitted to the HSTs that are being fitted with "plug doors" for a further lease of life.

Believe me, it is not particularly pleasant working near this and it is a rare issue I wholeheartedly agree with the RMT over!

165/6 onwards have retention toilets.

Paddington station used to have a team of guys called "the well gang" their job was to hose down the platform wells once a week, they just started at one side at the start of the week and did a pair of platform wells a day.  When not doing that they were part of the Pway gang

...I don't think the name is short for cesspit. I've never seen any "bangers and mash" in a cess.

A quick etymological investigation reveals that cess probably derives from cesspool, which is a corruption of suspiral meaning vent, water pipe or settling tank.

In railways, the cess does act as a drain, but principally for rain falling on the track ballast. The volume of sewage emanating from train toilets may be unpleasant, but it doesn't justify that much civil engineering.

After the cab has passed it would be very reasonable to try and have a short conversation before you were able to resume work.

A short conversation may not be wise when a train without retention toilets is passing. I'd keep my mouth firmly shut, lest I get an unwanted helping of bangers and mash.

Fair point Ellendune although this stretch is rather segregated from the existing 2 track section and other activity (such as the lone shoveller, moving truckage surveyors etc) seem never to be so constrained by passing rail traffic.

Isn't there a 'sell-by' date for those trains without retention tanks to have them fitted? sometime in 2020? So all stock in use after this date will * all* have retention tanks. Hence those (and only those currently) going to Scotrail (and being shortened) are being converted as part of the shortening process (which is why the work has needed to be started)

I guess GWR need to do those short HSTs they are keeping for Devon & Cornwall too at some stage.

AAUI the deadline for retention toilets is the last day of 2020.  This is later than the accessibility modification deadline of 1 Jan 2020.  However, fitting electric doors and retention toilets to a MkIII are both big jobs which it makes sense to do together and I think doing them together was the original plan and is still what is happening at least for the Scotland-bound sets.  AAUI, the toilet deadline as well as being later is also just an internal NR deadline rather than an EU one so I can see the disability modifications being prioritised if needed and the toilet ones being allowed to slip.

NR has intended to apply the toilet deadline to heritage and charter stock, but has delayed doing so.

Surely someone can think of a way to get certain politicians to stand trackside in an appropriate location... maybe we could ask them to re-announce the GWR electrification, or a new scheme for Portishead involving diesel buses on ordinary roads... with a bit of co-ordination you could get all the toilets flushing at the same time...

Now for the how. AAUI, there is only one winding in an autotransformer

AAUI the deadline for retention toilets is the last day of 2020.

Forgive me ... AAUI?   Familiar with AIUI (As I Understand it) but AAUI isn't in our acronyms list  :-\

I agree with SandT Engineer, the only thing worse than being sprayed trackside is working on traction and rolling stock especially on set that has just come off of a run on a wet day  >:(

The fitting of retention toilets on trains is something that should have been done when the Mk3 were designed.

Pedant alert!

I think we should restrict ourselves to the term 'retention tank(s)'; a 'retention toilet' is surely just another name for a bucket and on a train this would quite rapidly become very messy!

Blue lights if anyone does want to try and spot one of them lit beneath the grime!  Personally I can't wait for the new toilets to be fitted as the current ones fitted during the refresh continue to not be fit for purpose - running out of water or blocking far to quickly and easily.

The only reason the toilets block far too easily is because passengers flush all manners if things down them!

Points raised here. (https://youtu.be/OEv6dqVPLSM)

Of course, what goes into a retention tank has to come out somewhere. From the BBC (http://www.bbc.co.uk/news/uk-england-berkshire-42049943):

Reading rail depot building 'will treat train toilet waste'

People fear they will endure the smell of sewage from a rail depot extraction plant "100 yards" from their homes.

Residents in Cardiff Road, Reading, claim a new building on the site will extract sewage from train toilets.

Reading Borough Council has queried whether Network Rail, which has not commented on the building's use, had permission to construct it.

Rail bosses, issued with a noise abatement notice on the site, say the building is within "permitted rights".

Great Western Railway (GWR) and Network Rail directors face prosecution if they fail to comply with the legal noise abatement notice, issued last week, within six months.

Jonathan Dart, chairman of the Bell Tower Community Association, said residents found out about the sewage extraction use after the noise complaints were made.

'Caught by surprise'

When asked what the latest concerns of neighbours were, Mr Dart added: "It's going to be smell and noise.

"We are not sure actually once they have treated this waste, how they are going to get it out."

Deputy council leader Tony Page said the local authority was "caught some what by surprise" by the effluent treatment development.

Great Western Railway bosses said buildings on railway land fell under "permitted development rights".

A Network Rail spokesperson added the train operator was "not in a position to comment" while it considered its "legal options" over the effluent extraction plant.

GWR previously said new electric trains being introduced will reduce noise levels.

Now I note the unsupported segue from "extraction" to "treatment" of the trains' waste. I had a quick look at the original planing application for the depot (http://planning.reading.gov.uk/fastweb_PL/detail.asp?AltRef=102191&ApplicationNumber=10%2F01380%2FFUL&AddressPrefix=&Postcode=&CaseOfficer=&ParishName=&AreaTeam=&WardMember=&Consultant=&DateReceivedStart=&DateReceivedEnd=&DateDecidedStart=&DateDecidedEnd=&Locality=&AgentName=&ApplicantName=network+rail&ShowDecided=&Decision_Made=&DecisionDescription=&Sort1=FullAddressPrefix&Sort2=DateReceived+DESC&Submit=Search), which refers to two CET plant rooms and connection points within the building for servicing Turbos and outside it. One of these plant rooms was to be in the eastern sidings (which do adjoin houses; the depot proper doesn't) and was to be for IEPs. Obviously a lot has changed since then, but I can't see any further application that relates to this.

It does look from the words* that the extracted "waste water" is to be sent to the foul sewers, just as it is from stations' own facilities. I can't see why this would not be permissible, though it may lead to a charge from Thames Water.

Which I'm sure they are expecting, as they must be doing this at other depots.

I suspect that extraction will be done through suction/creating a vacuum hence sucking it out of the trains, but why this should create fumes outside the depot surprises me! I'm sure the staff working there wouldn't put up with it either, and it won't be a problem. Neither will the building assuming it's on railway land, as it must be covered under permitted rights.

BBC South tonight had a piece where they showed a building a-building which supposedly was not in the submitted plans, and was well to the east of the depot proper. The railway is all on an embankment, with a road beside it inside the retaining wall, but on the Google earth pictures you can see a rectangular extension to the upper level that wasn't on the 2010 plans. It's roughly level with the bollards in Cardiff Road, and I think this building must be there (you can see an outline of one from above).

This is close to the "east CET plant room" on the plans (which is there), and apparently NR have said it is for processing the CET waste, and built under permitted rights. Since then they have clammed up and are talking to their learned friends.

I wonder if Thames Water have told NR they do have to do something to this stuff before it goes down the drainfoul sewer? But this is, of course, hardly a new kind of operation (except for much of GWR). So what has happened elsewhere?

Is this just the regular stuff like you or I might flush down a loo, or is it mixed with chemical toilet fluid? If it's the latter, and they are (as indeed they are) intending to dispose of it in bulk, then I suppose it might be reasonable to ask them to treat it before putting it in the sewer.

I think it's just .... but kept in a tank. There's an RSSB note on "Water recycling technology for train toilets", but while that mentions black water in passing (as it were) it's mainly about the grey stuff. I think the idea is that black water waste has to be just got rid of, while grey can be recycled or reused, either on-board or at depots. The obvious use is flushing said CETs, and the benefit is less fresh water needed and less storage space taken up (or that could be taken as more black water storage - so less likelihood of getting filled up and leading to an out-of-service WC).

The Reading depot planning words made a biggish thing about using rainwater off the not insubstantial area of roofs for carriage washing. If they now propose to treat (which at least suggests reuse) some train waste water, could that just be this grey water recycling? That would presumably save sewerage charges, in only minimally. But in that case it should net them more brownie points from RBC than half-bricks from the neighbours, so their shtumness is puzzling.

Grey water in the context of a train means the water draining from the sink rather than the toilet.  I had assumed that even on a modern train with toilet tanks, anything that goes down the sink still ends up being dumped on the track.  Is that not correct?

I can't see any environmental advantage or money saving in burning fuel to cart grey water back to a depot.  Unless the railway is working to a bonkers regulation which not only outlaws the dumping of toilet sewage onto the track but also makes it illegal to dump sink drainage water which will be no more microbially contaminated than rainwater running off a train roof on which pigeons have been roosting and no more chemically contaminated than rainwater run off from a train which has been through the washer.

The rectangular extension to the embankment itself (in the location you describe) certainly is on the DMU depot plans from the original applications.   It just doesn't have anything shown built on it back then.   

I wouldn't say this recent new building being discussed and the original east CET plant room are 'close' however,  I reckon they are about 300m apart.   Perhaps it is additional capacity for more and longer trains.

Google Earth's satellite view is more up to date than Google maps.

You're right this new building isn't close to the east CET - that was just the closest identifiable structure. Actually, it's almost in line with Reading ATS - and behind numbers 141-145 Cardiff Road.

But I can't see this base on the 2010 plans, by which I mean the Jacobs 1:500 set of detailed layouts (seven sheets). There's a smaller, layby-shaped extension shown to the east. That really is a for layby, since the access road is single track with passing places. It's shows with "substation 4" within an outer retaining wall, maybe at a lower level, but as built has several small sheds next to it, all at high level.  There is a nearly rectangular outline 80 m to the west but that's a site boundary, to be taken up by a shallower natural embankment. That land was never taken, and the embankment there no different in profile.

Next coming back east (and behind 147-149, marked on the plan) is another layby, a bit wider but still only 4 m. Then right next to it is this new, 9m wide, building platform. It may be in a more recent plan somewhere, even if not one that says exactly what they were going to do there.

I think the issue for planning is this: if you say "we don't need your permission to do this, but to show what nice friendly neighbours we'll be we'll tell you anyway" - and then you do something not just different but bigger - people get suspicious and annoyed.
