British Rail Class 07

The BR Class 07 was a class of fourteen 0-6-0 diesel-electric shunting locomotives built in 1962 by Ruston & Hornsby of Lincoln, specifically for shunting duties at Southampton Docks. Unlike the general-purpose Class 08 and Class 09 shunters that worked freight yards across the BR network, the Class 07 was designed to meet the particular requirements of the docks environment: tight curves, mixed rail and road surfaces in the dock estate, and the need to handle wagons being loaded and unloaded from ships on the quayside.

The locomotives were powered by a Paxman 6RPH six-cylinder diesel engine producing 275 hp, driving through a diesel-electric transmission to the three coupled axles. The 0-6-0 wheel arrangement was standard for shunters of the period, giving good adhesion at the low speeds required for dock work. The relatively modest power output was sufficient for the short, heavy shunting moves that dock working demanded.

The Class 07s spent their entire BR careers at Southampton, replacing earlier steam shunters that had worked the docks. As freight handling at Southampton changed through the 1970s and container traffic grew, the traditional wagon-by-wagon dock shunting that the Class 07s had been built for became less prevalent. Withdrawals began in 1973 and the class was entirely retired by 1977. Several examples passed into industrial and preserved railway use; a number survive today on heritage railways.
