50013 Agincourt passes Walton Well Road, Oxford, on 21 May 1983 with the 1A75 07:05 Hereford to Paddington service. Apart from 50014 Warspite, which arrived at Doncaster Works two days after this picture was taken, the only Class 50s still in plain blue livery at this time were the first six refurbished machines. It is noteworthy that I saw half of this batch with two hours on this morning. 50017 Royal Oak was on the 1S61 06:45 Paddington to Edinburgh, an 50019 Ramillies worked the 1A25 08:05 Hereford to Paddington.
