    I’ve seen the occasional mention online, of finally splitting the Northern Line, by way of new tracks north of Camden Town, to eliminate the bottleneck. Apparently would allow 36tph in each of the cores.

    Is this an actual plan yet? Seems like a great idea on the face of it. A little bit of tunnelling work, and then a respectable upgrade in capacity.

    Its a flat crossing virtually at the ends of the platforms - they wanted to grade separate from the off but were restricted by where they could put the station apparently, and obv the huge amount of cash needed for all the extra tunnelling, etc - you would need to divert both lines north of Euston and build your separated crossings there - pushing the train switching crush to get the right branch back to Euston. Would help Camden but utterly fuck Euston should HS2 also end up parked there

    The junction at Camden is already entirely grade-separated. A train from either outer branch can head to either central branch without crossing on the flat.


    The issue is not congestion on the tracks but in Camden station itself. Full separation would mean far more people changing trains at Camden, already a very busy station. There's a proposed scheme to upgrade the station, with a new entrance North of the current one, with much larger interchange passageways: Improving capacity at Camden Town station - Transport for London - Citizen Space Current completion date is 2024/5 although there's no funding in place yet.

    The lines would then be Edgware-CharingX-Battersea and Barnet-Bank-Morden. If they don't call the latter the Southern Line I will be very sad.

    I think we’re done here. (Mods - please close the thread before crispy gets any more informative)

    They should do with doing something on the tracks too.

    There is a set of points at Camden that are the busiest points on the whole underground.

    Because they do more work then most points they break more often than most points. Need to be maintained more often resulting in closures. Etc etc.

    It’s the Northern line’s main point of weakness in my opinion.

    When the line is split, they won't be doing any work any more.

    A crossover between the two branches might still be advisable for flexibility and transfer of stock. Camden still might be the best place for that due to proximity of the split branches.

    Oh for sure. They'll definitely leave the connection in place; it just won't be a major stress on the tracks any more.
