Line has been closed since 1500, expected to re-open around 1630.

There was a need for double-tracking a further section to increase line capacity but this work has been completed.  The issue is at least partly lack of rolling stock.


If you are referring to the doubling North of Crosskeys to the former Aberbeeg Junction (Just north of Llanhilleth), then this work has not been completed yet. Last I heard it had been paused, although there was never any official source for this. As far as I am aware the aim is to deliver the additional services between Newport and Ebbw Vale by May 2021, so the passing loop will need to be available for then if this is the case.

I recall it being utterly standard practise for newly replaced tracks to be bedded in with an initial speed restriction, but (now that I thick about it) I've not come across that recently.  Perhaps this is just the older standard being applied with the higher temperatures being something of a red herring - or perhaps making for problems yesterday so the tracks haven't yet been fully stressed?   Fair enough - if that's the case, initial report was a bit confusing as it suggested today's temperatures caused the problem.

This is a planned TSR following track renewals over the weekend. 50mph in both directions between 19m4ch and 19m35ch, on the main lines.

Update: Just done some digging, turns out the speed has actually been reduced to 20mph ESR.

It does also mean one of the units will have no Coach D with the luggage and bike spaces.

This isn't the case, a coach was swapped with Virgin. This was a coach with a shop from the Virgin set which previously had two shops. This coach was then converted to have the luggage and bike spaces as on the rest of the XC voyager fleet.

The additional vehicles entered service a few months ago, the result being that 1V46 0640 York-Plymouth and 1S53 1325 Plymouth-Edinburgh (As far as Newcastle) are now double voyager sets, when they are not an HST. When they are an HST other services are strengthened instead.

Any missed stops or early terminations will soon be classed as 'cancellations' for the new performance figure percentage metrics.

This is what applies now, under the Cancellation and significant lateness metric (CaSL). A train is counted as being a CaSL failure if:

It is cancelled at origin.
It is cancelled en route.
The originating station is changed.
It fails to make a scheduled stop at a station.
It is significantly late (ie it arrives at its terminating station 30 minutes or more late).

Any train which is a CaSL failure also fails PPM. So therefore even if a train which has missed stops arrives at its destination on time, it is still a PPM failure.

Due to a fault with the signalling system between Didcot Parkway and Reading some Didcot Parkway lines are blocked.
Impact: Train services running to and from these stations may be delayed. Disruption is expected until 13:00 18/01.

Greetings from 1C12 at Goring and Streatley

Fast lines westbound closed ... everyone on the slow lines

Err - sorry - main lines closed ... everyone on the relief

Said to be a "broken rail" to us on the train.  Presumably the track is strong enough to take the new trains?

Defect in a set of points on the Down Main at Didcot East. The set of points have in the last 15 minutes been authorised for train movements when in the reverse position, this means everything will have to cross over to the Relief lines if using the Down Main.

.....here we go again...

 
Cancellations to services between Southall and Slough

Due to a speed restriction over defective track between Southall and Slough fewer trains are able to run on some lines towards Slough.
Train services running through these stations may be cancelled or delayed by up to 20 minutes. Disruption is expected until 14:30 18/01.
Further Information
Trains from London Paddington/Southall towards Slough/Reading, are unable to call at Hayes, West Drayton, Iver and Langley.

5mph ESR due to a broken insulated rail joint. Sounds like they are hoping to replace it this afternoon.

Are there problems with IEPs switching to electric power? I'm on the 0659 from Didcot, still on diesel leaving Reading.

Edit: diesel all the way to Paddington.

Yesterday there was a report of a missing sign on the Up Main for the changeover to Electric. Drivers were being advised at the Didcot station call or at a signal if not stopping not to raise the pantograph. This went on until this afternoon when normal working resumed. Not sure if this would be the reason though.

And that starts with why isn't 1P10 in P10/11 anyway? There's a gap for it to do that.

Whilst it may look like there is a gap at Reading, there isn't a sufficient gap at Didcot for it to get across from the Relief Lines onto the Main Lines. There is freight paths through Platform 3 shortly after its departure, so it isn't possible to hold the 387 in the platform that bit longer to go behind the Bristol-Paddington. I could see this train perhaps starting from Swindon when the wires eventually extend that far, it could then run just behind the Bristol-Paddington service from Swindon and use the Main Lines throughout. When the 110mph running times are used it could be quite a fast service from Didcot.
10  Journey by Journey / Cross Country services / Re: Points failure - Didcot 30/12/17 on: December 31, 2017, 12:28:24 pm
As does the XC service. It doesn't use the west curve, at least, noton the nights that I have been on it....

It is booked to use the West Curve, and does use it most nights if it is on-time. There is a situation where it can't use the West Curve and that is what happened with this train.

If the train reverses at Foxhall Junction on the Down Main, the West Curve is not accessible, therefore the train has to proceed into Didcot via the Didcot Relief Line and reverse again there. The train has to reverse on the Up Main in order to access the West Curve, obviously this causes disruption to services on the Up Main in unplanned scenarios like this. Similarly the 2145 Reading-Birmingham might get altered to reverse on the Down Main if there is disruption to services on the Up Main.

The points failure was at Didcot East Junction on the points which allow trains to travel between the Down Relief and the Up Relief, there was no detection at all at both ends. This resulted in no route between Didcot station and the Relief Lines and no access to the Down Avoiding Line.

09:33 public, so the train is scheduled to arrive 4 minutes late everyday, that's just silly

Not the only train in that direction that is like this. To a lesser extent 1003/1203 from Paddington are both booked into Plymouth a minute earlier to make the headline journey time, and have been for years. In more recent timetable changes Exeter also joined the party on these trains, 2 minutes earlier on the 1003 and 1 minute earlier on the 1203 in January.

Although arguably, in the case of 1003/1203 from Paddington, if the train is given a clear run and there are no temporary or emergency speed restrictions, the public times are perfectly achievable because they are the WTT with the engineering allowances removed.

In the case of the 0633 from Paddington the running time in the passenger timetable from Exeter to Plymouth is 51 minutes, which arguable is achievable - i've been on trains that have done the run in 50 minutes. However in this case the working timetable running time is 53 minutes, including one minute engineering allowance - so 52 minutes without the allowance. So whilst it might be possible to do the public timetable running time under the right conditions, it certainly won't be possible all the time.

I am sure there will be some promotion of the 17.07 but the change is no doubt to avoid clogging a platform at WSB waiting for a BRI path. This train returns ecs to BRI via the WSB up relief line!

Up Reception line to be pedantic!

HC are now saying that next weekend they will also be using Ealing Broadway as a terminus, while RTT still has them using Acton Mail Line. So it does look like a revision of the operational plan. It may be a bit cosy at Ealing, since the Greenfords are also reversing there all day - West Ealing P5 is not being used, for some reason.


Note that RTT does not show a time in the GBTT arrival/departure column, this means that technically those stops are operational and therefore are not advertised on Journey Planners.

If you look on journey planners for services from Ealing Broadway to Acton Main Line the only train to appear is the first Heathrow Connect service from Heathrow (which has a GBTT arrival time). For the other direction it is also just one service, the return working of the service previously mentioned! The same applied for the weekend just gone, not quite sure whether this was intentional or not.

I'm unsure of the usual number needed to run a 5car set - estimate being a driver, Train Manager, 1st class host & STD class trolley person - so 4. That'd then be 8 on a 10car.

7. The second unit doesn't require a driver!

Nor a Train Manager from what I have seen allocated, so 6.

Grahame, I would be a bit careful about the dwell times given by RTT.  To the best of my knowledge they are measured by the signalling system recording occupation and clearance of the platform train detection system section and don't truly reflect the actual stop time.  So the arrival time is when the first wheel occupies the platform section and the departure time is when either the platform section clears or the next section ahead is occupied.  Some train detection sections are longer than the platform itself and some of the ahead ones are some distance from the platform end.

RTT applies 'offsets' to the times provided by the train describer movement data. For arrivals these offsets are based on the time taken for a train to trigger the describer movement and come to a stand, and for departures the time taken for a train to trigger the describer movement after wheels start turning. Obviously there can be variation between different stock types, but unfortunately this is one of the limitations on reporting arrival/departure times in this way. Generally however RTT won't be hugely different to the actual time assuming the train gets a clear run into and out of the platform and isn't subject to any other issues such as wheel slip, etc, etc.

RTT has offset data for most of the country where train describer movement data is available, except in locations recently re-signalled where new data has to be collected. This is something that is on-going and hopefully will be available in the future.
