50023 Howe passes Blackthorn on 30 April 1990 with the 1G58 18:12 Paddington to Banbury Network SouthEast service. This, and an early morning up train, were the only loco hauled services over the Chiltern Line at this time. Unfortunately, for some reason I very rarely photographed the evening working. This was possibly because the Chiltern Line was even then quite overgrown in places, and as can be seen here, the late evening shadows could be quite a problem. This poor quality image will have to serve as record, because I never got around to improving on it before the Class 50s all departed for the West of England line a few months later.
