43023 passes Hay Lane (near Swindon) with the 1A63 12:45 Swansea to Paddington service on 15 September 1979. Apologies for the poor quality, but in addition to be taken on a Praktica, I took the picture slightly early, so some cropping has been required. At least I had the good sense to use Kodachrome 64, which allows considerable magnification, without showing any grain. Note the row of dead elm trees in the background. This was a common sight at the time, following the ravages of Dutch Elm Disease.
