The Class 07 0-6-0 diesel-electric shunter was built in 1962 to replace aging SR USA dock tanks at Southampton Docks. They were steadily withdrawn between May 1973 - July 1977, most of which were scrapped with some finding further uses as privately owned industrial shunters. Seven Class 07s have since been preserved.

A Class 07 was introduced in the Phorum Peninsula route. A derelict Class 07 is somewhat macabarely included in the Doncaster Works add-on as movable stock.
