BANK STATION: During escalator replacement work there is no step-free access to the Docklands Light Railway (DLR) and a reduced escalator service between the DLR and Northern/Central/Waterloo & City lines at Bank. A one-way system, via the staircase from the Northern line platforms, will operate for customers accessing the DLR from Bank station. Allow extra time to change between the DLR and Bank station in either direction.
