What Was the D2/1 Class?
The D2/1 class was a special kind of locomotive that ran on diesel fuel. It was designed to move trains around, especially for shunting (moving wagons in a yard). Only eight of these engines were ever made, making them quite rare.
Who Built These Engines?
The D2/1 locomotives were built by the North British Locomotive Company. This company was a well-known builder of trains in Scotland. They made these engines between 1953 and 1956.
How Powerful Were They?
These diesel engines had a Paxman 6RPH engine, which gave them about 200 horsepower. This was enough power to pull heavy loads, especially for their main job of shunting.
Speed and Strength
The D2/1 class could reach a top speed of about 14.5 miles per hour (23.3 km/h). While this might not sound fast, it was perfect for moving trains slowly and carefully in busy railway yards. They also had a strong pulling force, known as tractive effort, of 21,500 pounds-force (95.6 kN).
When Were They Used?
The D2/1 locomotives started working for British Rail in 1953. They served for several years, helping to move goods and trains across the railway network.
When Did They Retire?
These engines were retired from service between 1963 and 1968. After their working lives, they were taken out of use.
