NOTES: * Later in their working life a number of the BR/Swindon locomotives were fitted with air-brake equipment to work air-braked trains. TOPS codes were 03 for the BR shunters and 04 for the Drewry locomotives. None of the Class 04 received or carried TOPS numbers and only 123 of the 03 class were allocated a new number in the range 03004 - 03399. Two of these, 03370 and 03371 were formerly Departmental locomotives 91 and 92.

NOTES: No Hudswell-Clarke locomotive survived to be reclassified in 1968. Of the Hunslet designs, only the 0-6-0s were classified as 05 in 1968, including Nos. D2550-2618. TOPS numbers were given to one locomotive, No.D2554, which became 05001 in 1973.
