New A60 stock on the Metropolitan line
A northbound four car train of new A60 stock on the Underground's Metropolitan line. The first two cars are Nos. 5002 and 6002 respectively. Built by Cravens of Sheffield and delivered in 1961, the A60 stock was produced to coincide with the electrification of the line to Amersham and Chesham (previously the Metropolitan had been electrified only as far as Rickmansworth). As journey times on the Metropolitan take invariably longer than on other Underground lines (Amersham to Algate being 47 km), the A60 stock was designed to improve passenger comfort and reduce the amount of standing.
