text: GB Railfreight use re-engined Class 73/9 locomotives to haul the Caledonian Sleeper. They are used for the non-electrified sections of the route, running from Edinburgh to Aberdeen, Inverness and Fort William.
  Merseyrail Electrics
  Merseyrail Electrics had a fleet of four Class 73/0 locomotives (numbers 73001/2/5/6), based at Birkenhead North TMD, for use on shunting and other departmental duties. Two, numbers 73001 and 73006, were repainted into Merseyrail's yellow livery; they were later fitted with sandite discharging equipment and reclassified as Class 73/9. All four locomotives were withdrawn from traffic by 2002, and all were later sold for preservation.
  73004 was also owned by Merseyrail during this period. It was used as a source of spare parts and was the first to be cut up.
  Network Rail
  Network Rail inherited two redundant Gatwick Express locomotives, numbers 73212 and 73213, from its predecessor Railtrack. These were overhauled and painted in Railtrack's company's blue and green livery. They were used on engineering trains associated with an upgrade of electrical supply systems on the former Southern Region.
  A third locomotive, number 73141, was originally bought for spare parts, but was returned to traffic in case of failure of one of the other two locomotives. The locomotives were later repainted into Network Rail all-over-yellow with red buffer beams.
