This line, essentially a Bakerloo relief line, took over the Bakerloo line from Stanmore to Baker Street and continued in new tunnels south of Baker Street ending at a (temporary) terminus at Charing Cross, with a view to subsequently extending further eastwards.

The eventual extension was different from that originally planned and the new line branched off the existing one south of Green Park station in the Westminster direction. In doing so, it isolated the short section to Charing Cross station, which was closed at the same time as the new extension opened.

The escalators leading up to the Northern Line (Strand end). There are three escalators here.

The escalators leading up to the Bakerloo Line (Trafalgar Square end). Only two escalators were provided here; the centre flight is a fixed staircase.

Looking downward from the fixed staircase at the circulating area at the bottom of the Trafalgar Square end escalators. The escalators for the Northern Line can just about be made out at the far end of the circulating area.
