The Eastern and North Eastern Regions (E&NER) originally classified them DJ14 under a scheme devised in 1954 where "D" denoted Diesel, and "J" denoted the 0-6-0 wheel arrangement.[1][2][3] They were subsequently reclassified by the E&NER D2/5 (February 1960) and then 2/12A (June 1962).[4][2][3] They were reported in several sources as having received the TOPS classification Class 05, along with Hunslet shunter D2554 (the last surviving member of Class D2/8 (2/15A from 1962)),[5][3][2] though this was in error, and the D2/5 machines are not listed as such in the latest works by Marsden, 2011.[6][7]
