how many underground stations are there that are no longer used on london underground?

Answer 1

Probably the asker wishes to know about abandoned, derelict stations, rather than stations that have transferred out of LU's use.

1. Abandoned stations. This is what the BBC claim is a comprehensive list.

2. Transferred stations. There are many other former underground stations that are now used by the railway network. Many have been mentioned before (e.g. the Bakerloo Line reached Watford, and there was a Central Line extension beyond Epping) but I won't repeat any of the station names. However, no-one has mentioned the former branch of the Northern Line, which connected Finsbury Park to Moorgate, but was handed over to (then) British Rail, following the Moorgate Tube Crash of 1975. As a result two of the six stations on the branch (Essex Road and Drayton Park) are no longer served by London Underground.

3. Name changes. I remember Trafalgar Square (Bakerloo Line) and Strand (Northern Line) stations being merged into one station called Charing Cross, and the station that was called Charing Cross was renamed Embankment. However the full story of these particular station name changes is far more complex than that.

4. The Post Office also had a driverless underground railway system which transported post across London and had nine stations. It closed in 2003.

I hope this is interesting.

Answer 2

Quite a few - the ones i can think of are Post Office (near bank) and Aldwych (closed in the late eighties). I am sure that one was also closed up as a grave for the dead who perished down there when sheltering in WW2.

Answer 3

York Road, between Kings X and Caledonian Road, you can see the lights and platform as you go through it. Think there used to be one in Muswell Hill too.

Answer 4

There are about 40 - including a whole additional section of the (Bakerloo?) line that was built but never used.

Gloucester Road (one unused platform originally used by the Metropolitan Railway)
