LIST OF BRITISH RAIL POWER CLASSIFICATIONS

British Railways, later British Rail, used a list of power classifications in order to categorise its main line diesel locomotive fleet. This list depended on the power output of the locomotive, and classes are listed below. A common misconception is that the first digit of the class number shows the type. This is usually correct (e.g. a Class 47 is a Type 4) but occasionally incorrect (e.g. a Class 31 is a Type 2).
