The history of London Underground's rolling stock is as complex as the history of the network itself. A wide variety of types have been operated, from the early days of steam locomotives and carriages through to today's electric multiple units. The different types used are listed here.

Note: Stock shown in red has been withdrawn from traffic.

[edit] Tube Stock

This is the general designation applied to the trains specially designed to run in the restricted space available in the tunnels used on part or all of the Bakerloo, Central, Northern, Piccadilly, Victoria and Jubilee Lines. The dimensions vary between individual designs but the common feature is the ability to run through a circular tunnel of approximately 13ft/4m diameter (the precise tunnel size varying between lines).

[edit] Sub-Surface Stock

This is the general designation (also known more simply as "Surface Stock") of the Underground trains constructed to width and height dimensions closer to those commonly used for railway vehicles in Great Britain, although in some cases (e.g. A60/62 stock) they slightly exceed various standard dimensions or clearances. They are used for services on lines which currently share, or have previously shared, use with non-Underground trains and where no section required the use of smaller diameter "tube" tunnels.
