  Description
  This class of 49 locomotives were built in two batches using English Electric components. The first six locomotives were built by BR at Eastleigh Carriage and Wagon Works and introduced to service during 1962; they were built to the Hastings Line gauge, numbered E6001-E6006 and classified as type JA. With the introduction of TOPS in 1968 they were to have been classified as Class 72, to differentiate from the later built units. However, instead they became Class 73/0. In the early 1970s the locomotives were renumbered 73001-73006.
