At Cheltenham Racecourse Station. The locomotive is No 55 019 Royal Highland Fusilier. There was a good 30 minute layover so the engine was stopped and people were allowed in the cabs and to have a peek through the doors into the engine compartment. I was surprised at just how limited the view forward is - like looking through a letterbox.

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.

A total of 22 were built and they were rated at a top speed of 100 mph. They have quite an enthusiast following and this was a well attended event to celebrate 40 years of Deltic preservation.
