The British Rail Class 07 diesel locomotive is an off-centre cab dock shunter used in Southampton Docks, to replace SR USA Class steam locomotives. It is a 0-6-0 diesel-electric shunter built by Ruston & Hornsby in 1962. They were originally numbered D2985-D2998 and later given the TOPS numbers 07001(D2985)-07013(D2997), D2998.

[edit] Operation
The remaining members of the class that had TOPS style numbering applied, were also equipped with high-level air brake pipes - allowing them to move Southern Region Electric Multiple Units. This was not their principal work but they were greatly employed around their home-depot on general shunting duties. They were relatively high-speed for shunters and it was envisaged they would be used to trip local traffic to/from Southampton docks. In practice, they were seldom used for this because they suffered from hot axle boxes when used for extended periods of "high-speed" running. This was also a problem if they had to work to an area away from Eastleigh so they were moved by road when attending BREL for heavy work. Other shunter classes would commonly have their side-rods removed and traction motors isolated and would then form part of a train heading in the appropriate direction. Class 08s were commonly moved in this fashion at up to 35mph - overnight wagon-load trains being utilised if possible.
[edit] Post-BR use
The locomotives were short-lived and this class had been withdrawn by British Rail by 1977. Several were bought for industrial use and have subsequently passed into preservation. One locomotive, no. 07001, is mainline registered and is owned by Harry Needle Railroad Company (HNRC). All surviving locomotives are listed below.
- 07001 / D2985 - Owned by HNRC based at Barrow Hill
- 07005 / D2989 - Owned by HNRC - stored on Battlefield Line
- 07007 / D2991 - Preserved on Kent and East Sussex Railway
- 07010 / D2994 - Preserved on Avon Valley Railway
- 07011 / D2995 - Privately owned at St Leonards-on-Sea
- 07012 / D2996 - Preserved on Lavender Line
- 07013 / D2997 - Preserved by Heritage Shunters Trust
[edit] Technical details
- Engine: Ruston/Paxman 6 cylinder, 4-stroke, 6RPHL
- Main Generator: AEI RTB6652
- Traction motor: AEI RTA6652, spigot mounted on a double reduction, axle-hung, final drive gearbox
Locomotive (air) and train (vacuum) brakes were fitted from new. Air train braking was added later, in some cases with high-level air brake pipes for use with Southern Region electric multiple units.
[edit] Industrial locomotives
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, none had the same engine output, train brakes or other 'mainline' features.
[edit] In fiction
An example of this class of diesel can be seen on the Thomas the Tank Engine and Friends TV Series, in the form of Salty the Dockyard Diesel.
