50046 Ajax passes Hay Lane, just to the west of Swindon, with the Thursdays only 1A71 09:00 Penzance to Paddington service on 16 June 1983. This seems to be a very little photographed train, which is not really surprising, as it only ran on ten days during the 1983 summer timetable. Passengers from Penzance could leave half an hour later on the 1A49 09:33 HST departure, and arrive in London an hour and half before this train got there, after its long jaunt via Bristol.
