I haven't used Bank for a while but it
was always overcrowded in the rush hour on the northern line platforms. Can't
see how they can improve that short of tunnelling a new diversion tube tunnel
like they did at Angel.

That's what they are doing, a new Northern line southbound tunnel.

is probably a better page.

"More than 200 engineers and staff will work on site at Bank 24 hours a
day until 2021."

Opted out of the working time directive, clearly.
