This is, as far as is known, a full list of post-1973 codes used to identify train maintenance depots. Depot codes were applied as stickers to rolling stock, usually (but not always) underneath the data panel; an example on a class 73 is shown below; the observant will note that these form the inspiration for this site's logo.

Some codes changed over the years and some were reused, so there are depots and codes listed more than once. Where known, when each code was used is shown, together with whether a depot is still in use (with operator) or has closed. For NLC, TIPLOC and Stanox codes for depots, the reader is referred to this page. CRS codes, where allocated, are shown here.

Several codes on this list do not appear on other equivalent lists. They mostly represent stations at which basic maintenance could take place by mobile fitter (e.g. PD, Paddington). These were derived from this British Rail Business Systems pocket guide 2.2Mb file starting on page 8. Such codes existed even if not used on trains or the 'depot' didn't have an allocation. Further through you can enjoy various codes including repair and faults, train heat and, at the very back, liveries. Note that pages 17, 20, 34-36 and back cover had no content and are not included here. There are a couple of known transcribing errors: depot HG is shown as Hastings (should be Hither Green) and depot PO is shown as 07627 (should be 07267).

Codes with comments in bold red type are believed to be correct, but require confirmation from a separate source to verify.

Depot operators are given, where possible, for those sites operational since privatisation in 1994. Much information is available via the ORR's licencing regime (including from exemptions granted). However, this primarily focusses on the passenger operators. Detail is in many cases limited or entirely absent for non-passenger sites, especially large works and heritage sites.

Many sites, for example Oxford, are officially considered to be sidings rather than depots so do not have an operator. Pre-privatisation, such distinctions were largely irrelevant. Depot codes were allocated as convenient and are not reliant on any given operator or legal status.

The operator should therefore be considered to be the responsible company as far as the ORR is concerned. Some sites are split with different companies responsible for different parts (though in practice working in cooperation). Equally, some sites are treated as a unified whole by the regulator but are split into multiple depot code areas. Note that the depot operator is not necessarily the same as the primary user. Additionally, on occasion company A carries out maintenance on company B's trains at company C's depot; this list only names the latter.
