The British Rail Class 07 locomotive is an off-centre cab shunter for use in Southampton Docks, to replace steam locomotives. A 0-6-0 diesel-electrical shunter built by Ruston & Hornsby, 1962. Numbered D2985-D2998 and given the TOPS numbers 07001(D2985)-07013(D2997), D2998.

Engine is a Ruston/Paxman 6 cylinder, 4-stroke, 6RPHL. Traction motor is an AEI RTA6652, spigot mounted on a double reduction axle-hung final drive gearbox. Main Generator is an AEI RTB6652. Train air and vacuum brakes were fitted and these included high level air brake pipes to match the Southern region electric multiple units.

The builders classified these locomotives as LSSE and although other locomotives were built for industrial use to this (and the similarly styled LSSH diesel-hydraulic) specification, non had the same engine output, train brakes or other 'mainline' features.

This class was withdrawn by British Rail by 1977. Several were bought for industrial use, and have subsequently passed into preservation. In addition, one loco is mainline registered, no. 07001, which is owned by HNRC. All surviving locomotives are listed below.

An example of this Class of diesel can be seen on the Thomas the Tank Engine and Friends TV Series, where there is a diesel called Salty the Dockyard Diesel, based on one of these types.
