Four sets of depot codes are presented here. The first is the post-1973 TOPS two character depot codes, together with CRS codes where appropriate and known. The second is an older list of four digit numbers that look at first like NLCs, but are unrelated. The post-nationalisation, pre-TOPS alphanumeric codes are shown and finally, the Great Western Railway alphabetical and numerical codes are listed.
