Second blockade is 18 Nov to 14 Jan so effectively 2 months. I'd hazard a guess that they'll aim to get the knitting up quickly at the east end and then tested in terms of clearances / tension etc and then aim to get the juice switched on over Christmas when they have no train movements anywhere for two days so they can get the electrical isolations. Then they'll have to check that the current draw and other things before handing the line back. I expect they'll be hoping a class 710 or two have arrived by then so they can test the trains under full possession for clearances, signal interference etc. Depending on when LO think they can start running longer trains then we might see the longer platforms come fully into use when services restart. Obviously if the Class 710s are late in being delivered then we might get more weekend possessions for testing given we have reduced daylight hours. I cannot see them being tested on that line, too disruptive and short, and virtually impossible to test at full authorised speed, more likely to do their 250 miles proving on something like Peterborough to Hertford loop. Much more sensible to pick a line with only 1 or 2 trains off peak and where you can run at maximum speed easily. Clearly fault free mileage accumulation is likely to be done somewhere else. I assume that's what you're referring to. However you still need to make sure the 710s actually work on the line they're going to be deployed on. Let's just hope they do fit and that the many tight electrical clearances under structures on the route are as designed and the design was right!! It is extremely tight in a number of places with wires running side by side not in a vertical alignment.

I've seen elsewhere a picture of a finished LO 710 at Litchurch Lane, there where no available pictures of whether the interior was completed. I assume the fault free mile accumulation will take place on the WCML as more 387's are delivered to GWR and paths become available and the DC testing will take place on the BML. I predict overnight and testing in possession hours to be utilised to see how the units far on the line itself, with daytime testing slot in between the service similar to the 172's testing and introduction.

On first glance, the white / orange below the cab does look a bit messy - otherwise it lools pretty good and a bit more colourful than the 345s.

I'm not a fan. Still, we complain, we get used to it soon enough...

News has reached me of the work to raise Crouch Hill station road bridge.
Network Rail has registered a road closure on the London Register of Roadworks from 01/01/2018 to 12/07/2018 for this work. Such a long duration is necessary because of the plethora of utilities that run under the road surface (including BBC cables that serve the transmitter at Ally Pally) that need to be moved before raising the bridge can even start!
Network Rail currently have a dispensation to run electric trains under the bridge in its present position, so rail services will not be affected once they have re-started in the new year (apart from one or two weekend closures when they need to get trackside to raise the bridge).

Interesting. Utilities are usually a nightmare - all of the bridge replacements that TfL have been doing have taken months and months just to even put a utilities bridge in place and then months more to actually move things. Only then does the bridge itself get touched. I suspect Network Rail may have some issues over station access at Crouch Hill as the steps from the platform are aligned with the bridge height so these may need replacement and that won't be a two minute job. I suppose a temporary footbridge could be installed to allow one entrance at a time to be worked on but it will be very high because of the wires. The temporary bridges on the TfL Rail line (as part of the station mod works) are precipitous.

But possibly not for a long period given the bridge raising can be done over a weekend apparently. There is a local diversion route but it's quite narrow as we've discussed before.

The line User Group recently met with Network Rail about the progress of the electrication works. Here is a tweet of theirs explaining what should happen. This is also a quote from their latest news iten available at www.barking-gospeloak.org.uk/index.htmObviously credit for the above goes to the User Group. I am just repeating what I've read.

14 Jan for handing back per text, 14 Feb for completion per tweet, is completion really a month later or is one date wrong ? Short answer - don't know and haven't asked. Longer answer - I think what they are saying is something like this but I am speculating. 14 Jan - blockade ends, wires all up and energised and route safe for passage of diesel trains 14 Feb - planned testing of the electrical infrastructure / wiring all complete. Apparently there are lots of different tests done including with kit that can "stress" the equipment to relfect a worse case loading. We've mentioned this before but Class 92s and Pendolinos have been used to "stress" other electrified routes. I expect the Class 710s will also be tested on the route before this deadline. Mar - we hope to get ORR sign off after we have presented all the documentation and test results from the final tests. Usual process is that assurance evidence is presented progressively as tests are undertaken/works are signed off by relevant engineers. After March - Class 710s enter passenger service.

Hopefully by March a handful of units will be constructed to be deployed and drivers trained up. That said I'll miss 2+2 seating on the GOBLIN.

Not fussed about the 2+2 seating as it's so blooming hard to get on trains in rush hour between Leyton and Blackhorse Road. I'll quite like to be able to get on a train when it turns up instead of having to brave the roads in Waltham Forest - I can sometimes walk faster from Leyton to Walthamstow these days.
