English Electric Type 3B Battery Electric Locomotive

English Electric built hundreds of small electric locomotives for industrial service shunting from 1920 to 1951. Many were the Type 3B which were mostly built at the Dick Kerr works in Preston. While the basic configuration and bodyshell was the same the traction equipment and power collection setup depended on the customer's requirements and could vary greatly. Power collection could be via pantograph, tram pole or third rail. Some also had batteries though depending on the size of battery needed this could require the body being extended.

Coal power stations such as Spondon in Derby were often enthusiastic users of electric shunters [1]. The Derbyshire & Nottinghamshire Electric Power Company bought 3 of these locomotives for the Spondon power station. They were used on a mile long branch line to the power station. They remained in service until the mid-1980s when they were replaced by diesel locomotives. Two of the three locomotives have been preserved. Other examples of this type of electric locomotive have also been preserved.
