56073 Tremorfa Steelworks accelerates away from the Oxford pick up stop and crosses the Castle Mill Stream (a backwater of the River Thames) on 20 February 1994. It is working the Pathfinder Tours 1Z40 09:00 Reading to Sheffield 'Standedge Stomper' railtour. Amazingly, it has already had one change of traction, with 47823 working the short distance between Reading and Didcot Parkway. 56073 worked as far as Birmingham New Street, with 60066 onwards to Manchester Piccadilly, then 47356 to Wakefield Kirkgate, 58008 to Sheffield, 37358 to Derby, 31242 & 31285 to Crewe and 56033 back to Didcot Parkway, where 47823 (the only repetition of the day) was waiting to take the train back to Reading. Phew!
