Until the 1980s, the Bakerloo line was mainly worked by 1938 stock. 1972 stock operated briefly on the line during the late 1970s until it was transferred to the Jubilee line when it opened in 1979. From 1983, the 1938 stock began to be replaced by trains of 1959 stock from the Northern line, but this was a temporary measure until 1972 stock became available. The last 1938 stock train was withdrawn on 20 November 1985. From 1986, the 1959 stock was transferred back to the Northern line and was replaced by the current 1972 stock.
