Stock type Subsurface

The London Underground C69 and C77 Stock, commonly known as the C Stock, was a type of below ground rolling stock used on the Circle, District and Hammersmith & City (formerly Metropolitan) lines of the London Underground between 1970 and 2014. These were replaced with S stock trains, which also run routes on the District, Hammersmith and City, Circle and Metropolitan lines.

Stop of usage

The C Stock was replaced between 2012 and 2014 by S7 Stock.

A tour took place on 29 June 2014 showing a lot of the area covered by the stock during its time on the rails. One train (5721+5531+5578) was kept for this tour with one held as a reserve in case of breakdown (5533+5517+5592).

Post-withdrawal use

Transport for London has given away two C77 driving motors to educational establishments, and another from the same sub-series to the London Transport Museum: these are 5701, 5720 and 5721.
