With me foolishly taking no notes on this trip of

the numbers and workings very few have been identifiable. However, there is no doubt as to which Class 50 this one is with its nameplate being clear read. 50007 'Hercules' approaches Bradford-on-Avon from the Bath direction working an unidentified up working for Paddington composed of largely Mk. IIC non-air-conditioned stock with its pressure ventilation system instead. 50007 had just over a year in this guise before entering Doncaster for its much-needed complete rebuild emerging in large logo livery during February 1983. Of course, this would mean significant alterations to the filtration system and a new scavenger induction fan with the consequential loss of its charismatic 'hoover' soundtrack!
