The Class 01/5 designation is used for a multitude of privately owned diesel shunters which are cleared to operate on the mainline rail network. Class 01/5 includes shunters used by the Ministry of Defence, Train Operating Companies (TOCs) and other railway support companies. The designation has nothing to do with the original
Class 01.

An example of one of these locomotives is 01 509 which is a 1963 built Ruston & Hornsby 0-6-0DH shunter operated by Chiltern Railways at their
Aylesbury depot. The designation can also cover shunters which belonged to other TOPS classes in their original BR service. 01 553 is a
Class 11 which also became a Class 01/5 for mainline use, it has now been preserved again.
