From Wikipedia, the free encyclopedia
The London Post Office Railway 1930 Stock and 1936 Stock was built by English Electric. These units comprised the bulk of the fleet from the 1930s until the introduction of the 1980 Stock. The articulated units were designed to replace the earlier unsuccessful 1927 Stock, which were prone to derailments.
An initial 50 units were ordered, being built in two batches from 1930-1931. They reused electrical equipment from withdrawn 1927 Stock units. Due to an increase in traffic levels, ten further units were built in 1936. The numbering details of units is shown in the table below:

After the introduction of the 1980 Stock, some units were retained, being renumbered into the range 35-51 in 1984. All remaining units were withdrawn in 2003 when the system closed.
Several units have been preserved, all of which are from the second batch of 1930 Stock. These are listed below:
