Bank (Walbrook) to Cannon Street OSIsDec 19, 2018
Now that the new entrance to Bank Station, within the Bloomberg building on Walbrook, has opened, TfL have added a new OSI between Bank and Cannon Street LU. The OSI still works with any entrance to Bank station, but the Walbrook exit is far and away the nearest. This entrance takes you down to the Waterloo and City line platforms and has access to the rest of the station from there.
The details have been added to my OSI list, and to the map page for Bank to Cannon Street.
