The Chiltern Line, when it was still a rural backwater, complete with semaphore signalling. The 2G34 08:25 Banbury to Marylebone Network SouthEast service leaves Princes Risborough station on 29 August 1987, led by 51665. Despite this line being relatively local to me, I took very few photos of the route in the days when the staple traction was these Class 115 four car DMUs.
