The Thameslink infrastructure has a complex are of dual voltage provision between Farringdon and City T/L, and that has also been engineered to allow for changeover without stopping, even though all services do stop anyway.
Paul
The Thameslink Dual Electrified Area does not do an on the move change over, there is no need in fact. I did write that all services stop anyway, however the original Thameslink infrastructure and train specifications published by DfT» both required changeover on the move to be made possible, long before the 700s were even ordered, and before the current TOC▸ was in place. I would suggest that the OHLE equipment has probably been engineered to allow this, even though from what you have explained, it is pretty much redundant. However the main reason for mentioning Thameslink was to show that the concept of changeover on the move was not without precedent... Paul

The actual work has proved much more complex than anticipated because the estimation process was deliberately kept light. This could be because the cost of finding the cost of every nut and bolt would have been horrendous instead of just enormous, money which could have ended up down the drain had the answer been too big to allow the project to continue
I think this encapsulates very well what I was trying to say. If you wanted robust estimate you would have had to have to have done a feasibility on the method of construction of each bridge and then liaised with the relevant local authority and engaged with the public to establish what method of working might be acceptable. DfT» is the pair of handcuffs that links the NR» to the government. It isn't brilliant at the job, but what do you expect from the civil service?
A civil service where policy staff actually stayed in the same department long enough to learn something about the subject and where having some people with technical skills is considered necessary, might have done a better job. ORR» is busy getting on with finding new things to regulate , to justify its existence.
The same comment about technical skills. Asking questions rather just benchmarking. Though in their defence they did not sign off on the scheme because they knew the data was not there - instead they did this curious half way house of signing off a budget then getting NR to come back with more information later. Presumably this was because saying it was not going to happen was not politically acceptable. So perhaps the finger really needs to point back at DfT - though Ministers rather than Civil Servants.

Very true. I am a civil servant. Though I have done many different jobs, they have all been within the same department, and I have acquired a depth of knowledge and experience that is hard to find elsewhere. Which is why I am retiring soon.

When the noise became unbearable, we invited the chairman to come along to see for himself ...
That approach stood out for me as a reminder of the way this forum sometimes works ... helping to inform 'both ways', by informing understand, and by understanding being much less concerned, more appreciate, and more helpful in feedback for the common good

Thanks for posting that update, Jason. Unfortunately, as so often happens whenever I catch such headlines, I think it's referring to Bath. Sorry.

William Huskisson MP▸ was the first person to be killed by a train while crossing the tracks, in 1830. Many more have died in the same way since then. Don't take a chance: stop, look, listen.

Where Piccadilly and Victoria come together with a blooming long walk between them, as I remember from my yoof - but I think there's more to it these days. Nearest tube for HM on her way home to Buck House - at least the nicest walk home for her.

Having worked at Green Park for a few years in the past, this is is a considerable blow to the area.

Sorry, ellendune, for my rather oblique reference: I was thinking of the old Green Park station in Bath - see https://en.wikipedia.org/wiki/Bath_Green_Park_railway_station

Err, isn't that a 158 in the picture used to illustrate that article? If the services are to be provided by 158s, why is lack of electrification a problem?

Bath drop in session today ... 1 December 2015 16:00 - 18:30 Brunswick Room, Guildhall, Bath, BA1 5AW I had an email about this a couple of weeks ago, followed by a "recall" so I wondered if the session had been cancelled. However, I've just done a search and found it's still on the meeting list at http://www.networkrail.co.uk/great-western-route-modernisation/banes/and that page was "updated 30th November2015" so it's declared as being up to date.

I've noticed they've got wires up at the Stoke Gifford depot, just seem to be single wires, not the full catenary.
