50015 Valiant arrives at Moreton-in-Marsh on 16 August 1987 with the 1B40 16:10 Paddington to Hereford service. Note the semaphore signals. On the original 6x7 slide all four separate posts can be clearly seen. Unfortunately this picture was taken on one of the few Agfachrome 100RS films that I tried around this time. Agfa promised that they had conquered their transparency film's infamous tendency to turn a funny colour with age (1960s CT18 being a prime example). I can now confirm that they hadn't! This picture has been salvaged with Photoshop from a fogged purple mess! Kodachromes from the same period still look as good as they day they came back from Kodak.
