The London Underground 1960 Stock was a class of electric multiple unit for the London Underground Central line. Twelve motor cars were supplied by Cravens, and pairs were made up to four cars by the addition of two converted standard stock trailers. A production run of 338 motor cars was shelved, due to the time needed to assess the new features and the cost of converting the trailer cars. Some of the pre-1938 trailers were later replaced by 1938 stock trailers.
