Throughout the 1950s and 1960s the Northern line was worked exclusively by 1938/1949 Stock trains. They were starting to show their age by the late 1960s; the first withdrawals from the Northern line took place in the early 1970s with the introduction of the 1972 Stock trains.
With the 1959 Stock approaching life-expiry, five ex-Bakerloo line trains of 1938 Stock were given a further overhaul in the mid-1980s. These were then used on the Northern line for a further two years, the last day of passenger service was on 19 May 1988. They were then sold for further use on the Isle of Wight.
