The London Underground A60 and A62 Stock,[2] commonly referred to as A Stock, was a type of sub-surface rolling stock which operated on the Metropolitan line of the London Underground from 12 June 1961[3][4][5] to 26 September 2012, and on the East London line from 1977 until 22 December 2007, when it closed to be converted into London Overground (except in 1986, when one-man operation conversion of the fleet took place).

The stock was built in two batches (A60 and A62) by Cravens of Sheffield in the early 1960s, and replaced all other trains on the line.

At the time of its withdrawal in September 2012, the stock was the oldest on the Underground, having been in service for over 50 years. It was the only stock to have luggage racks, umbrella hooks and separate power and braking controls, and the last stock not to feature any automated announcements.
