I believe that the Class 73s' diesel engine was used by some drivers when arrving at/departing from the airport, to give a smoother ride when crossing gaps in the third rail as the train switched tracks.When used for more than a brief period on diesel power - particularly when driven hard as would be necessary on the Gatwick Express - 73s are well known for overheating. Apparently the diesel engine is only intended for minimal use, and the cooling system is low capacity. |
