The Redbridge incident was only a test drill to get a core sample. Very fortunately for the driver of the train that hit it, it missed him on its way to getting embedded in the bulkhead. A much bigger auger penetrated the NCL tunnel near Old Street a few years ago. It later transpired that the test bores had not found the tunnel, and over a dozen piles were planned to be put right through where it ran. Fortunately the auger broke drilling the first one, and the driver of a passing train was alerted by the mysterious pile of mud that had suddenly appeared. It seems that none of the council planning department, architect, surveyor, or anyone else involved in the project even knew the line was there. (There are, of course, "no tube lines in Hackney") Clicky

If you've not used it at all, it's worth checking out - with all the NSE tiling about, it's like going back to the 1990s.

There may be no tube lines in Hackney, but the local knowledge of LBH planning department should have been sufficient to ring alarm bells. There are of course plenty of railway tunnels in LBH, notably those north of Hackney Downs, as well as the GN&C.

As a bit of an aside with things penetrating tunnel roofs, when I worked on the W&C in BR days, I pulled in to Waterloo one lunch time. Just ahead of the platform towards the siding a huge black snake about 4" diameter was finding its way out of the tunnel roof and onto the track. Not wishing to see it become live or for it to damage my train. I stopped the job.
People from High Places came down to look and were puzzled. People from high Places went upstairs. Contractors were installing cable TV cables under the roadway on the access road under Platform1, and they wondered why the cable push suddenly became easier. It had found a hole in the trunking and had curled itself round in a big loop in front of my train!

Just had a look at the Network Rail GOBE project page. They have published their latest set of update letters for residents near the route. Looks like the platform works, being done by TFL contractors, started on 22 December and continue on from now to reopening in "late Feb". The wiring train starts in January and will work from the Gospel Oak end of the route. It will be working 24 hours a day - 2x12 hour shifts. Lots of work still happening with extensive track and formation replacement between Wanstead Park and Woodgrange Park now and other stuff happening in pockets of activity along the line from now until it reopens. Looks like the Lea Navigation closure, for the bridge replacement, has been extended for about a further week in January. There also seems to be a lot of more minor works like fencing, raising bridge parapets etc to give adequate post electrification clearances. There's also quite a lot of troughing work to do in advance of installing new cables.

I thought the original reopening was earlier than "late February". Has something gone wrong?
A while back project updates from Network Rail implied the works were about 80% complete and proceeding as planned or is this delay down to something TFL were organising.

The early official line was 8 months from June, or just "February" (see quotes below and tfl.gov.uk/info-for/media/press-releases/2016/may/gospel-oak-to-barking-line-closure-starts-4-june), but snoggle has seen NR documents stating 4 February. 8 months on the whole line seems really excessive. Half the line at a time (Walthamstow - are there any crossings left?) might work, to feed in at least to some alternative routes.... Unless something has changed then I think the Standard doesn't have the full details. The Network Rail documents have long shown the blockades to be in two phases - one affecting Barking - South Tottenham section for a long time and then switching to a full closure for about three months. I can't see a TfL press release at the moment which is what I would have expected. There isn't a NR one either on its website. The quote from Mike Stubbs is also odd in that it seems he thinks the possession length is still being negotiated which I can't believe is the case now. I also find the Standard's description of the line as "neglected" is rather stupid. It's old sure but it's not been devoid of investment in recent years. EDIT - I have gone back and checked NR's rules of the route documents for East Anglia for 2016 and 2017. There are continuous weekend closures of the whole line through to end September. Barking - S Tott closes from June right through to 4 Feb 2017. S Tott- G Oak is fully closed from early October so a lot of disruption. The next closure is in March 2017 for the usual cyclical possessions that Network Rail have. Interestingly only the weekend closures show up on the TfL 6 months look ahead. While I understand the point you make it's perhaps no great shock that the rail replacement service may be awarded on a firm time period with an extension. We know TfL have been jumping up and down to get the total timescale pulled back and the line is due to reopen in the first weekend of February so the concept of the real programme, regardless of NR's blockade published programme, being to the end of December is not unrealistic. I don't expect anyone to really "pull a rabbit out of a hat" and reopen the line in early Jan 2017 rather than 4 weeks later but perhaps Arriva have been a bit "too honest" about their RRS contract in their press release. There's obviously a lot of work to do but if NR can relay tracks, stick up all the masts and catenary, run all the new cabling and replace the bridges by early Jan then all that's left is platform extension works and joining all the wires to the leccy supply which we know doesn't take place until after services resume. Having platform works run over a number of months once trains are running is no hardship as 4 car trains aren't due for 15 months anyway.

The start date of 4 Feb appears to be borne out by National Rail enquiries, 3 Feb being the last date of the RRS there

The start date of 4 Feb appears to be borne out by National Rail enquiries, 3 Feb being the last date of the RRS there Well the NR documents have now disappeared from view - both the local notices for the GOBE work and the possession plans. I hate website redesigns that obscure previously available information. I agree the possession info has previously said 4 Feb as the end date. I am a tad sceptical that the wiring train can wire both roads from G Oak to Barking and crossovers and link lines in under 3 weeks even working 24 hours a day. It only started work on 12 Jan and suspect it can't go beyond Upper Holloway until TfL are clear from the bridge replacement works (after tonight!). A tamper is also due to run at the western end on 18 Jan which will probably assist in achieving clearances in one or two spots. I think the "end Feb" date has emerged recently as a way of managing risk and public perception. Most of the travelling public won't have a clue about NR possession plans and what was agreed. The TfL Planned Closures list recently went rather vague about the GOBE works - can't think why. Network Rail tweeted a reply to someone last week that TfL would announce the reopening date "shortly". I will be genuinely surprsied if passenger trains resume operation on 4 Feb - I just can't see the wiring being complete. NR also have to take a decision about whether the wires are energised, if the actual hanging of the wires is running tight to schedule, so as to reduce the risk of cable theft on the route. I dare say we will find out soon enough.

I will be genuinely surprsied if passenger trains resume operation on 4 Feb - I just can't see the wiring being complete. Trains may be able to run once the bridge works are complete, even if some of the wiring remains to be done in later possessions, some time before the 710s are delivered.

Don't weekend closures continue for some time after the total blockade finishes?

Don't weekend closures continue for some time after the total blockade finishes? There are none showing in the TfL closure look ahead apart from a partial Sunday closure until lunchtime Barking - S Tottenham in April. Another forum is saying that the blockade has been extended to 28 Feb 2017 and operators were approached in December about such an extension. This makes much more sense given the scale of the wiring works - 100km of wire to be strung, checked and I assume "tested" (however you test catenary?). Last time I looked (more than a week ago) we still didn't have steel masts installed all the way between Blackhorse Rd and S Tottenham. I know there are the issues with the VL tunnels underneath but even so the bridge works over the Lea are pretty much done now so I'd have expected the steelwork to be in situ by now. The only other obvious impediment might be the old footbridge at Blackhorse Rd - I can't work out if that's being kept or replaced given part of it has been removed (the sloped bit linking into the ticket hall).

Curious. TfL for London Overground shows a good service, even on Goblin. Does that mean it has reopened early?

Post by dazz285 on Jan 26, 2017 15:03:50 GMT
No trackwork took place & only, so I'm told, 1 signal moved slightly & a banner repeater added near Wanstead Park. "The infrastructure works have been heavily delayed since December and it is now unlikely that all the OLE work would have been completed by the reopening date, also there are still problems with passenger access to Blackhorse Road station and we are awaiting confirmation if this will be open to Overground Services when we begin running again." Once I've been briefed next Wednesday I'll see what I can pass on.

In places track was lifted, the trackbed lowered and new track laid. Speaking purely as a passenger I would describe that as "trackwork", presumably the engineers have a different definition.

Post by dazz285 on Jan 26, 2017 20:30:46 GMT
Sorry my bad. Yes there were certain areas of track that have been lowered to allow for the installation of the overheads. I've been more interested in the OHLE installation & the 2 new bridges that have been replaced over the River Lea.

Once I've been briefed next Wednesday I'll see what I can pass on. Interesting but not surprising. If they're starting to run test trains again I don't see how that fits alongside the wiring train working 24 hours which is what was reported by NR in December. Hmmmm. There are going to be a lot of fed up people if access at Blackhorse Road is not ready - that's one of the busiest stops on the route. Again, though, not hugely surprised as the footbridge has been disconnected from the ticket hall for months with no obvious sign of how the link would be reinstated. I'll have to go and take another look and see how the lift towers have progressed. I've been half expecting the entire old bridge to go and one of NR's modular bridges to be craned in but I think it's too late for that. And to think TfL were pressuring NR for a shorter blockade.

The weekly travel information email that TfL sent out on Thursday morning (26th Jan) for the forthcoming weekend states "There is no service between Gospel Oak and Barking until late February."

The weekly travel information email that TfL sent out on Thursday morning (26th Jan) for the forthcoming weekend states "There is no service between Gospel Oak and Barking until late February." Those E Mails have been saying that for a few weeks now. Ditto the Planned Track Closures list on the TfL website. Previously each week / weekend had an orange entry showing the blockade duration. However they were removed and replaced by a banner statement at the head of the closures document. I suspect this was deliberate once it became clear that the 4 Feb blockade end date was not going to be achieved in terms of restoring passenger services. It will be interesting to see how late TfL leave things in terms of announcing the actual reopening date and whether there are other things like early finishes, late start ups and many more weekend closures required to allow the work to be completed.

Scheduled opening is 27th Feb, which will not be reneged upon for political reasons. There will be nearly no wires up though

Yes that's right. Some of the SPS has restriction on who supplies it and they are simply flat out. There are also issues with fabrication over here as the fabricators are so busy. The upshot is that practically all the steelwork will be in place come opening day, wiring to be done later.
Reading through this thread, perhaps I should clarify that the blockade was needed mainly for the heavy civils, which would have been impossible to achieve otherwise.

Reading through this thread, perhaps I should clarify that the blockade was needed mainly for the heavy civils, which would have been impossible to achieve otherwise. Once again thanks for the info / update. Much appreciated. I'll refrain from any specific comment or criticism about the steelwork issue because it wouldn't be fair to expect you to explain further. I wish it had been made clear early on what the blockade was actually for. I think a decent number of people have expected to see wires dangling over the tracks by the time the line reopens to passengers. I was of the view that perhaps the wires might not have been energised come Feb 2017 but at least they'd have been in place thus allowing the "plugging in" and any fine tuning to take place subsequently. Those comments aren't directed at you personally more a general remark that the "powers that be" could have been clearer much earlier in managing expectations. As ever with heavy civils that are often "invisible" to the travelling public I can see people turning up at the end of Feb going "why have we had no trains for 9 months? I thought the line was being electrified." There will need to be some good comms being done to explain what's happened and what is left to do. And that's on top of the long standing issue of explaining why sparkly new electric trains won't be there until this time next year. Looking at the NR GOBE Twitter account all people are asking is "when does the line reopen?". Perhaps TfL need to get announcing and quickly?

Apologies for my use of unexplained abbreviations. It's quite usual for the civil engineers to be somewhat less appreciated than those carrying out the more visible work!
I could have a rant about where the project is but I have already risked getting myself in hot water.
