from 1972, morden depot ceased to be the preserve of just 1938 stock, and by 1978, there were five types of stock in use on the northern line and stabled at the depot. as part of a major programme of updating the rolling stock on the system, the piccadilly line was equpped with 1973 stock. this allowed the 1956 stock and 1959 stock on that line to be transferred to the northern line, and some of the 1938 stock to be scrapped. to make up the number of trains required, 30 trains of 1972 mark i stock were ordered, and subsequently, a second batch of 33 trains, known as 1972 mark ii stock, was ordered, for eventual equipping of the jubilee line, then under construction. they operated on the northern line from november 1973, to enable additional 1938 stock to be scrapped, and were gradually transferred to the bakerloo line, as more trains of 1959 stock were displaced from the piccadilly line. the first train of 1959 stock arrived in november 1975, and by 1 january 1978, 56 and a half trains had been transferred. the allocation at the beginning of 1978 comprised 10.5 trains of 1938 stock, three of 1956 stock, 56.5 of 1958 stock, 30 of 1972 mark i stock and 15 of 1972 mark ii stock, making 115 in total, although only 95 were required from day to day. morden depot was used to stable 39 trains to run the passenger service at that time, with golders green supplying 17, and the remaining 39 being stabled at highgate and edgware depots, and on sidings at high barnet, highgate woods, and golders green.
