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 ventilation shaft that serves the Jubilee line platforms. The perspective is hard to fathom but this view is looking directly downward. A higher view showing the gantry from which this photo was taken, was featured in the 2008 film The Escapist.

The light coming through the windows on the left is from the southern of the two Jubilee platforms.
