One thinks of the IC125 units as DMU's but in reality they are permenantly coupled locomotives. As such the Class deisgination is Class 43. The only locomotive, it seems, able to replace a Class 43 is another Class 43. At the moment it is proposed to refurbish the Great Western and GNER Fleets. Seen outside Doncaster Works early February 2005. Copyright belongs to Andrew Ducker and South West Trains photographs used with permission. Photographs taken by Andrew Ducker on Canon EOS10D.
