Bank/City/Monument/KWS/Cannon St.

A few questions about the complex.

The Met R proposal of 1914 had the slope to the W&C platforms replaced by an escalator. Has anyone come across any drawings of how this would have worked?

There seems to be a very strongly held consensus that the area is extremely crowded, which undoubtably it is. However the red herring of the BoE's vaults always comes up. The various proposals over the years seem to suggest that there is a bit more (not much though) room down there than the popular opinion seems to indicate.

Leading on from this, what exactly will the current works deliver in terms of enlargement? Has a JLE style enlargement of the entire complex not been examinied, and if so was it political, ecconomic (lack of spondoola) or useage reasons, or site limitations, health & saftey requirements for reconstruction, modern construction restrictions/requirements/standards or a poor CBR (or a combination of all of these) that killed off any such aspiration?

I was under the impression that the DLR would be relocated eventually as part of a rebuild, however this TfL document (http://www.tfl.gov.uk/assets/downloads/corporate/5-Investment-Programme-Report.pdf page 9) shows that the southbound running tunnel of the Northern line would also be moved?

What happened to the Walbrook square enterance of the W&C (http://www.tfl.gov.uk/corporate/media/newscentre/archive/7631.aspx); recession cut back? Pity as it seemed TfL had put some effort into it. Why though was a connection to Cannon Street not investigated; they are extremely close to each other there.

Lastly, where would one obtain a station plan of the indicative layout of the station post upgrades, rebuilds, expansions, relocations and Step-Free works? Such a document must surely exist somewhere? FoI request to TfL perhaps?

Thanks to all who can respond.

I'd be interested in why it's necessary to move the DLR and the Northern s/b. And you're right - what has happened to the Walbrook St entrance?

[Chris M]

AIUI the movement of the southbound Northern Line platform is part of an Angel Islington (the station)-style rebuild to improve platform safety. Without looking at any official diagrams, I'm guessing this is what the plan might possible be (maroon represents track, yellow platforms and passenger tunnels.

I would expect people the central walkway would get quite busy as people would start using it to bypass the DLR platforms when interchanging from Monument.

[Ben]

If they had another segregated walkway they could make each one way only, perhaps doubling capacity? Bit of postulation, but why cant the central line platforms be moved eastward aswell to straighten them? Not a clue whats going on there; whats the masterplan for the station?

I believe the answer to that is in the name of the station. The vaults of the bank of England are quite close.

Certainly on the east side of Bank, legend claims that the Central curves to avoid the vaults...

I thought that was because of some law requiring it to go under the streets?

Yes, that had a lot to do with early tube building schemes aswell!

The law didn't require the lines to go under the streets, that was just a consquence of the law meaning that the railway companies get permission of the owners of the land they tunnelled under. To save dealing with (and paying lots of money to) hundreds or thousands of property owners they generally built the lines under the streets. I think there was also compensation for vibration that needed to be paid as well. In some cases they did deal with one or two land owners to go under their property, but it was the exception rather than the rule.
Obviously, it's also much easier (and cheaper) to build cut and cover tunnels under streets than under houses.
