British Railways shed codes were used to identify the engine sheds

Motive power depot

Motive power depot, usually abbreviated to MPD, is a name given to places where locomotives are stored when not being used, and also repaired and maintained. They were originally known as "running sheds", "engine sheds", or, for short, just sheds. Facilities are provided for refuelling and...

The London Midland and Scottish Railway was a British railway company. It was formed on 1 January 1923 under the Railways Act of 1921, which required the grouping of over 120 separate railway companies into just four...

 (LMS) alpha-numeric system was extended to cover all regions and used until replaced by alphabetic codes in 1973.

System of codes

The coding system had its origins in a reorganisation of locomotive operation and maintenance on the LMS in the 1933-35 period. It grouped all sheds into districts with a main shed, given the district number followed by the letter A as its code, and subsidiary sheds with the same number followed by B, C, or D etc. Many sheds were also responsible for sub-sheds where day-to-day servicing could be carried out but which lacked the facilities for intermediate or heavy overhauls. The extension of the system to all regions was brought into use in 1950, each region being given a block of district numbers:

• 1 – 28 London Midland Region
  London Midland Region of British Railways
  The London Midland Region was one of the six regions created on the formation of the nationalised British Railways and consisted of ex-London, Midland and Scottish Railway lines in England and Wales. The region was managed first from buildings adjacent to Euston Station and later from Stanier...
  
  
• 30 – 41 Eastern Region
  Eastern Region of British Railways
  The Eastern Region was a region of British Railways from 1948. The region ceased to be an operating unit in its own right in the 1980s and was wound up at the end of 1992...
  
  
• 50 – 56 North Eastern Region
  North Eastern Region of British Railways
  The North Eastern Region was a region of British Railways from 1948. It was merged with the Eastern Region in 1967. It was the near direct post-nationalisation descendant of the North Eastern Railway, that had merged with the LNER just over 20 years early....

  The Southern Region was a region of British Railways from 1948. The region ceased to be an operating unit in its own right in the 1980s and was wound up at the end of 1992. The region covered south London, southern England and the south coast, including the busy commuter belt areas of Kent, Sussex...

Many codes changed as districts were re-organised and as regional boundaries changed over the years. For example, the former LMS shed at Goole was initially 25C as part of the Wakefield District. In September 1956 the district was transferred to the North Eastern Region and split between districts 53, 55 and 56; Goole became 53E in the Hull District. This district was itself merged with the York District in January 1960 and so Goole was re-coded again to become 50D. The changes accelerated with the contraction of the railway network and modernisation, both of which reduced the number of locomotives in use. For example, the Inverness district had five sheds and seven sub-sheds in 1950 but these had been reduced to a single shed by 1967.

On 6 May 1973 all the remaining depot codes were replaced by new two-letter codes. These no longer included any kind of district hierarchy, but were more suitable for use with the TOPS

 was allocated to a particular shed and an oval, cast metal plate with the depot code was bolted to the smokebox on the front of the locomotive. When locomotives were transferred between sheds the plate was taken off and replaced with one from the new shed. Locomotives moved between a parent depot and its sub-sheds did not need this change as they shared the same code.

With the introduction of diesel and electric motive power the system of allocation became changed. Main line locomotives were capable of operating greater distances between servicing and, very often, depots only held the equipment and spare parts for servicing a limited range of locomotive classes. This resulted in them being allocated to a smaller number of depots and reallocations became less common. For instance, the 309 Western Region
