43139 leads the 1A25 11:00 Bristol Temple Meads to Paddington service past South Moreton (Didcot East) on 1 December 1983. For a change, I decided to go for a wider shot, and include the rustic wooden fence in the foreground. This, along with virtually everything else in this picture, has now disappeared. The iconic HSTs have been replaced by Class 800 EMUs, Didcot Power Station and the gasholder in the background have been demolished, and even this viewpoint no longer exists, due to the electfrication of the route.
