Site: Maida Vale station (1 memorial)
W9, Elgin Avenue
The plaque is at the foot of the staircase leading down to the escalators. The ugly concrete lump that you see in our photo, to the left, is actually the building behind. That to the right does seem to be within the footprint of the station but we don't know what it might be. The station has no lifts so it can't be a lift head.
