The Standard Stock ran as 6-car trains until 1947, when 8-car trains became possible after Wood Lane was replaced by a new station at White City. More cars were transferred from other lines as they were replaced by 1938 Stock. In the early 1960s there was a plan to re-equip the Piccadilly line with new trains and transfer its newer Standard Stock to the Central line to replace the older cars there, some of which had been stored in the open during the Second World War and were becoming increasingly unreliable. However, after the first deliveries of 1959 Stock were running on the Piccadilly it was decided to divert this stock to the Central line, together with extra non-driving motor cars to lengthen the trains from 7-car to 8-car. 1962 Stock was ordered to release the 1959 Stock for the Piccadilly line. The last Standard Stock train ran on the Central line in 1963, and by May 1964 all 1959 Stock had been released to the Piccadilly line.
