There is a 3D model of the travelator at Bank in the Depot* of London's
Transport Museum at Acton Town, showing it in relation to the W&C
platforms, the rest of Bank station, and the streets and buildings
above. It is evident that the W&C platforms are some way down Queen
Victoria Street, probably nearer to Mansion House station than Bank.

There's a map of the W&C at:

which shows them under Queen Victoria St, but at the Cheapside end.
