A class 55 'Deltic' diesel electric locomotive pulling into Winchcombe station. The driver has just applied a bit of throttle to keep up momentum into the station. The locomotive is No. 55 019 Royal Highland Fusilier.

The Deltics were named after their power plant. The Napier Deltic is a triangular (delta shaped) two stroke diesel with 18 cylinders,36 pistons and three crankshafts developing 1650 horsepower and driving a DC dynamo to feed traction motors in a Co-Co configuration. Each locomotive has two engines, although only one was in use on this lightly stressed run.

A total of 22 were built and they were rated at a top speed of 100 mph (but apparently one once hit 125 mph downhill). They have quite an enthusiast following and this was a well attended event to celebrate 40 years of Deltic preservation.
