Network rail plans to close Tan Hill level crossing and replace it with a footbridge because it has a "high risk of accident"

Tan Hill level crossing in Wokingham which could be replaced by a footbridge

Plans to replace a dangerous level crossing with a footbridge have been deferred.

Wokingham Borough Council's planning committee were last night due to consider Network Rail's plans close Tan Hill level crossing and replace it with a footbridge.

The level crossing, which forms part of a footpath, is across the London Waterloo to Reading train line, close to where it and the Guildford line fork behind Wokingham Superbowl.
...
The rail company said the crossing carries a ^high risk of accident^ as trains can reach speeds of up to 70mph in both directions and a curve in the double track section can make sighting trains difficult, along with sun glare.

In in 2012 there was a near miss on the crossing.

The plans are now expected to be considered by the committee next month.
(That next meeting will be on July 23rd.)

This links to a more detailed previous article:

Quote
...
A survey last year revealed 80 to 90 people use the crossing on weekdays which increases to an average of 105 during the weekends.

The survey also found unauthorised use and trespass and criminal activity and a ^significant number^ of unaccompanied children using the crossing.

New train station could be added to Montague Park housing development

Safety fears were raised with Network Rail stating ^the highest risk to the public is a fatality occurring^.

In in 2012 there was a near miss on the crossing.

A report into the proposal said: ^Therefore Network Rail believes the replacement bridge is the only safe solution.^

The ^700,000 plans also include moving the footpath leading to the crossing around 56 metres via a stepped footbridge on both sides of the track.

Wokingham Town Council said it agrees to ^support the proposal but requests that consideration be given to meeting the aims of the Greenways project by ensuring the bridge is designed to be suitable for use by cyclists. An ideal solution would be a single bridge across both railway lines^.

Network Rail said ^may be in the future the situation is reviewed^ however this would not be until the current stepped bridge over the nearby Guildford railway line is up for renewal, and that is ^not scheduled in the foreseeable future^.

Network Rail has included a cycle gutter in the project, which means cyclists can also use the bridge.

Nationally Network Rail is spending ^130m to improve safety and reduce risk where a public highway meet a railway.

The plans are recommended for approval at tonight^s Wokingham Borough Council planning meeting at Shute End at 7pm.

The application by NR is for a Footpath Diversion, specifically for a Railway Crossing Diversion Order under s.119a of the Highways Act 1980.

The briefing for the planning committee is here (http://www.wokingham.gov.uk/EasysiteWeb/getresource.axd?AssetID=285975&type=full&servicetype=Attachment).

At this stage this is not an application for planning permission, though any new bridge will require such an application.

A few of points about this crossing:
  • It puzzles a lot of people - why would you have a bridge across the (unelectric and usually less busy) line to Guildford, and a footpath crossing over the 3rd-rail electric line to Ascot?
  • The speed of 70 mph is in the briefing, apparently from NR themselves. However, there is a 30 mph restriction through the station starting right next to it - and almost all trains stop anyway, so actual line speeds may be below even that limit.
  • I've added some pictures. The main approach from the town side - the important side for its staggering-home-after-a-night-out users, who are one of the main high-risk groups - has an old wicket gate and some new fencing to discourage wandering off beside the track. The view from this side, the inside of the curve, along the track is not good. And note the proximity of the speed sign.
  • The map in the council briefing has the word "Subway" next to this crossing. I imagine this comes from the underlying large-scale OS map. That's weird.
  • The name "Tan Hill" is not one I've come across before - it probably applies only to the crossing. The path would have been a very minor lane direct to the old Tan House on the Emm brook.

The only thing about this that seems to be at all controversial is the proposal to provide only steps, with a "cycle gutter", rather than a ramped bridge for cyclists and to meet section 149 of the Equalities Act 2010. NR's view is that the footbridge has steps only, and is not due for replacement in the foreseeable future. I'm not sure how old it is - it is not on the 1933 OS map, but looks older. Mind you, reinforced concrete always looks old as soon as it starts getting a bit tatty.

They also say that the ramps would need to be 400-500 m long, which sound excessive. Are they counting both ramps in this total length of "the structure"? Even if they are, and the rise needs to be 10 m (it doesn't - it would be closer to 7), that's 1 in 20-25. Does that mean that a road bridge can't be steeper than that because its footpaths would not meet the EA?

As it is, you will now have two bridges - so you not only have to climb up and then down, but between the two lines you will have to go down to ground level and back up. A span to link the bridges would be about the same length as the stairs down. I know exercise is good for you, but still...

Once upon a time, they were going to replace this with ... a road bridge over both lines, to allow the other level crossings to be closed. That plan (the IDR) was abandoned over 20 years ago, but this small part of it still has some merit.

Perhaps looking at something like this?

As a business, we have been through "legally level" requirements - I forget now but it was indeed something like 1 in 25

The Tan Hill Level Crossing in Wokingham is to close
 

A dangerous level crossing will be replaced with a footbridge in a bid to improve safety measures.

Tan Hill level crossing, which forms part of a footpath, is across the London Waterloo to Reading train line, close to where it and the Guildford line fork behind Wokingham Superbowl.

However, members of Wokingham Borough Council's planning committee agreed on Wednesday, August 20 to allow Network Rail to close the crossing.

Trains passing the crossing can reach speeds of up to 70mph in both directions and a curve in the double track section can make sighting trains difficult, along with sun glare.

A survey last year revealed 80 to 90 people use the crossing on weekdays which increases to an average of 105 during the weekends.

Safety fears were raised with Network Rail stating ^the highest risk to the public is a fatality occurring^.

In in 2012 there was a near miss on the crossing.

The survey also found unauthorised use and trespass and criminal activity and a ^significant number^ of unaccompanied children using the crossing.

The footbridge will include a cycle gutter in the project, which means cyclists can also use the bridge.

A couple of weeks ago I was coming along Wellington Road and spotted some scaffolding down behind the new (cricket cub) houses. So today I went to have a look. The footpath is closed off by barriers, but someone has pushed them aside so it was easy to get onto the existing bridge to see what's what.

And it's ... scaffolding. First I wondered how you'd build a bridge with the scaffolding in the way, then I though it looked more like a bridge for public use.

Looking in the WBC planning files, there is an application (numbered, oddly, 160497) for this temporary bridge, with drawings and calculations. It only went in on 22nd Feb, for comment until 8 March (there were none), and has not been decided. Network Rail make the usual point about this being permitted development (under the 1853 Staines, Wokingham, & Woking Railway Act), and are only asking for prior approval which "cannot be refused unless you are satisfied that the development ought to be and could reasonably be carried out elsewhere on the land, or the design or external appearance would injure the amenity of the neighbourhood and is reasonably capable of modification so as to avoid such injury".

The letter of application finished with "To confirm that you accept the proposed development under Part 18, Schedule 2 of the GDPO, please kindly issue a decision notice or letter stating that ^prior approval^ has been granted for our records in accordance with statutory timescales." That's brusque, and looks tactless too given that they started immediately. Putting 'prior approval' between inverted commas doesn't really make up for it.

So what's going on? There's some pictures of the site and a bridge, in which it says that "There are plans to install a new over span in 5 years to access the new facilities being built on the adjacent land." Of course! It's next to the Carnival pool bit of the Town Centre Regeneration Project, for which WBC's left left hand gave approval to its right hand at the outline stage last July (application O/2015/1056, including full approval for the new car park). And in the D&A statement for that there is indeed a pedestrian access across the track at a new angle to lead into the regeneration site, and in one sketch it's a "possible new pedestrian bridge".

So it looks more as if NR are doing what WBC asked them to do.

I've heard nothing about that plan to run a long bridge from the new leisure centre via the car park, both of which have now been built and opened. I wonder if the council has a plan or not? Because on 22nd November NR put in a planning application to WBC (number 223493) for a new bridge of their own, just on railway land, to replace the old bridge and temporary scaffolding one.

This work is all claimed as general permitted development, of course. It  needs three spans of one of their standard bridge designs, and makes no attempt to upgrade the crossing to be step free. After all, it (the one over the Guildford line) never was, and getting to it means walking the length of a muddy football pitch.

But the consultation (which ended yesterday) has seen 34 comments (though some are revisions) all, so far as I can see, castigating NR for ever thinking a stepped bridge could be acceptable. This was prompted by letters to the local paper, some from local councillors - who also put in some of the comments. I do wonder if our Lib Dems have got the hang of being the majority yet - don't they (as the executive) have a more direct way to engage with applicants?

I wonder what NR will say next? My guess is: "If you want to build a full-scale cycle plus pedestrian route (segregated, of course) across here, I'm sure we'll be able help you with the bridge part of it. Just don't expect to get one for free when we are just completing our crossing closure and replacing an old concrete bridge that's about to fall down."

Well, either it finally dawned on our councillors that they can't reasonably demand that Network Rail build a bridge to retain a non-existent step-free path - and on land they don't own - or else they knew all along but were just posturing. And in any case, given the very limited powers for a planning authority to refuse an application for permitted development, it was approved last week. The give-away is in Wokingham Today's text (https://wokingham.today/tan-house-bridge-replacement-to-go-ahead-but-council-has-until-august-to-make-this-change-to-its-plan/):
Quote
If the council can obtain land, funding and planning by August, Network Rail will be able to install ramps to make the bridge more accessible.

Today I got a letter from NR (a proper one in the post, too) to say they will start building their new bridge on Monday. That's almost frantic haste, by railway standards! It will take 16 weeks, they say.

This must be a CP6 funded project so needs to be spent this financial year; as rolling it over into CP7 is a whole degree of pain

I was wondering how much had been done in the first week - I can see from the level crossing that the old bridge has not been removed. The first work listed was their access road and compound, to be put on the playing field, so I went up there today to look. When I got there all this fencing was upright, and I thought the whole installation looked quite big.

I decided against squelching around it to look at the compound, either to the right or the left (shorter). As I turned round to leave, this row of fence panels was blown over by the wind. There was a mum with buggy coming towards the playground, so I told her I would tell NR about this, and I revised my opinion to "it may be big but it isn't clever". The tendency for this Heras-type of fencing to blow over should be known by professionals - I've seen it happen before.

I had to report it as an emergency, since I could not find anywhere for something a step down (urgent out of hours). A few minutes ago I had a look, which is hard as it's pretty dark (the street beside it now has LED lamps which don't produce spillover). So far nothing has changed.

PS: I've just spotted I got a phone call from a guy at NR while I was over the road. He told the machine he wanted more details - and then rang off with nothing more.

NR did put that fence up early the next morning, with a bit more bracing in the layout. I have not been to see it much since, as you can see very little from there. In fact the best view is from the town car park, but there was not a lot to see from there - by last weekend the foundations had just about been been done.

Then yesterday (Thursday) NR gave me (this time hand delivered) another contribution to my ever-growing collection of "dear neighbour" letters. This says that they are closing the level crossing and the roads up to it again all this weekend, to bring in the bridge span. It will come through the town centre at about midnight Saturday, but when and how it will get to its final position is not clear. Would it need to go that last short move along the railway? We'll see - or maybe not, if it happens in the middle of the night, as usual.

Anyway, the piers - if that's the word for these ones - are all lined up ready. And today temporary traffic lights turned up, from a different supplier from last time. Which is odd, as the full closure NR have announced does not need them. So I guess traffic will be allowed past, though not over, the crossing most of the time. And now, after midnight, work is starting and stuff is arriving on lorries.

That was  not 100% true. According to a man who knows (labelled Network rail, and he said "this is my bridge to deliver"), arrival in Wokingham was scheduled for Saturday night, but brought forward two weeks ago, when the possession was retimed, to Friday night. So that letter was partly out of date. But I looked out of the window before midday, towards the crossing, and saw a bridge trundling past (it had been lurking along the road).

Since then it's been all go, with a BIG crane's minders setting out the load spreading under its stabilisers. That's just for a lift off the lorries and onto a little train; there are two more cranes hanging about for the lifts onto the piers.

Do you know if they're doing the entire length of the bridge span this weekend?  I’m assuming from Google satellite view it is far too long overall to be delivered down one track in a pre-assembled length, ie there’ll presumably be two half bridges that will take the two separate routes at the junction? 

 IYSWIM.  ???

It came in two halves, still sitting waiting for the crane crew to sort themselves out. They are not that heavy, at 20t each, but still need a 300t crane because of the reach. Currently the crew are finishing assembling the sling, in the road just by my house!

You can see there how relaxed the crowd control was. We were only excluded from the footbridge and around the launch area during lifts of the bridge spans, and the station platforms were accessible all the time.

There was a guy with a drone doing video too.

No - he trades as Wokingham Aerial Photography. They have some photos and a video (with very annoying music) on his Facebook/Reels (https://www.facebook.com/people/Wokinghamaerialphotography/100088212252449/). There's a top view of the Ikea self-assembly junction kit too. I thought I found more videos on Instagram earlier, but can't find that now (or it may have been just photos).

Saturday was quite a spectacle, in the sense that it's not every decade you get a socking great mobile crane working at the corner of the street. It was also frustrating, with long waits with nothing happening except huddles of orange rainsuits debating (presumably) how to proceed. Then with no warning, something happens - often quickly. And as it was by then after dusk it was hard to see upwards, into a barrage of bright lights, or at the installation site, under limited site lighting, from the car park.

But I have a backlog of pictures. I'll start with the dramatis machinae:
A bridge of two halves
A toy train to take it down to where you can see one of the piers by the line
A Big Crane (Liebherr LTM1300 6.2)
... and a couple of these things (AC-55, I think). This one is going on-track, which makes a loud clunk noise.

Act one was setting up the crane for the lift (also in the first video above). This involves building pads for the outriggers, out of a combination of sandbags, planks, expanded polystyrene sheets, and a steel plate on top (better seen in the video at 8:40). This stuff comes on three artics (plus a trailer), together with the sections of the counterweight and the big spreader beam (p1).

This crane stacks its own ballast weights on a fixed platform in the middle of the vehicle body (p2). Two big lumps are slotted onto each side of this - 10t each bit. It picks up this stack, 96t of steel, with jacks on the back of the crane cab that lock into the ballast baseplate (p3). Only then can it fully extend the jib.

Act two was assembling the sling. In this case it has a massive beam to spread the strops in length, and two smaller ones to spread again in width. The big one was bolted together in the road (p1), I guess because that is flatter and stronger than the crossing. (p2)

Act three was attaching the sling to a bridge span. This took ages, as the plan was changed for some reason. The steel I-beams fixed under each end crosswise had had small extensions bolted to them on arrival, and the strops attached to the ends. This was tried (p3), but in the end the strops ran round the main tube at each side of the deck instead. This involved a rigger splitting the strop at the top so it could be fed along its new path.

And then, finally, the main event: the lift. The highest obstruction was the Vodafone mast by the station wall, so when lifted the span went round away from that, also avoiding the public footbridge (by then closed). It was lowered beside the signal box, onto the train of engineers' trailers (p1). For the second lift, onto the piers, two rail cranes operated in tandem (p2). One was on the tongue of land the centre span of the bridge crosses, the other on the track.

For the second span that crane moved to the other end, perhaps in the siding (I missed that - dinner time!). Obviously attaching the second span was much quicker, and in any case overlapped the work at the bridge site. This time the train of trailers didn't move into place until the span was in place (p3).

And by Sunday Morning, there is a new view up the line from the footbridge by the level crossing (p4).

Great set of photos thanks. 

Always useful to explain how complex these sort of jobs are, I think there were suggestions ‘elsewhere’ it should have been done at the same time as the resignalling and junction relaying, but that was clearly impossible...

Now that bit is in place,. what about the bridge itself? The design of the bridge itself got little attention at planning, what with all the shouting about (the lack of) ramps. But it is a bit odd, compared with what we are used to.

The width is quite generous, at 4m overall and 3.1m for the footway. The sloping sides are really quite high, as struck me when I saw a rigger using a stepladder to reach the top. The plans say 1.878m vertically, and it's faced internally with a "brushed stainless steel perforated panel". The centre span does not have this panel now, but I think it will be fitted. The drawing suggests, and the photo agrees, that the panel is more perforated at the top.

So it looks as if the views I was recording from the old bridges will not be coming back - not as clearly, and perhaps not at all. Now, is there a good reason for that obstruction? Even if this is meant as a standard design for all railways, including those with OLE, it does seem excessive. And as for the small kids who like to look at the trains ...

The stays preventing a "pack of cards" collapse look temporary, so I guess the stairs will be expected to hold it rigid finally.

Yes, while the staircase at the far side is in line with the bridge, this one has to be angled to avoid the car park (from which the picture was taken). Before the car park was built, there was a vague aspiration to continue the route from the footbridge on the level to, and through or around, the car park and on a walkway to the new Carnival Hub [sic]. That never made it into concrete, or even into a concrete plan.
