Graham Farish Class 31
263 members of the class were built between 1957 and 1962 and were intended for mixed traffic duties, originally on the Eastern Region. They were built at the Brush Electrical Engineering Company plant at Loughborough, originally with Mirrlees engines which were later replaced by English Electric ones between 1964 and 1969. They had a maximum speed of 90mph. Some with dual air/vacuum braking became subclass 31/1 and a further development of these created the subclass 31/4. A large number of retired members of the class have been preserved, including D5500 by the National Railway Museum.
The model was introduced by Graham Farish in 1995 and reintroduced by Bachmann in 2004. It has an upgraded mechanism with a twin flywheel 5-pole skew wound motor. This is the 7th version of the model to be produced by Bachmann and is in Network Rail yellow livery as 31602 Driver Dave Green (371-105).
