The British Rail Class D2/5 was a special type of diesel locomotive. It was built for British Rail in England during the 1950s. These locomotives were designed to move things around train yards, like shunting wagons.
Only ten of these locomotives were ever made. They were built by a company called Andrew Barclay Sons & Co. and used engines from Gardner.

What Was the Class D2/5?
The Class D2/5 was a small but strong locomotive. It was powered by a diesel engine, which means it ran on fuel, not steam. It also had a mechanical gearbox, similar to a car.
These locomotives were given numbers like 11177 to 11186 at first. Later, their numbers changed to D2400 to D2409. This happened between 1959 and 1961.
Building These Locomotives
Andrew Barclay Sons & Co. built all ten of these locomotives. This company was known for making industrial locomotives. They built these specific ones between 1956 and 1957.
Each locomotive had a special serial number from 402 to 411. This helped keep track of them during their construction.
How They Worked
The Class D2/5 had a Gardner 8L3 engine. This engine gave the locomotive about 204 horsepower. That's a good amount of power for moving heavy loads over short distances.
It used a Wilson four-speed mechanical gearbox. This allowed the driver to change gears, just like in a car, to control its speed and power.
Speed and Power
These locomotives were not built for high speeds. Their top speed was around 17.75 miles per hour (28.5 kilometers per hour). This was fast enough for moving wagons in a yard.
They had a strong pulling power, known as tractive effort. This was about 15,340 pounds of force. This power helped them push and pull heavy train cars.
Weight and Size
Each Class D2/5 locomotive weighed about 32 tons. This weight helped them stay stable and get good grip on the tracks.
They had six wheels, all connected, which is why they are called an 0-6-0 type. The wheels were about 3 feet 6 inches (1.07 meters) across.
Life on the Rails
The Class D2/5 locomotives worked for British Rail. They were mainly used for shunting duties. This means they moved wagons around train yards and sidings. They helped organize trains before they left for long journeys.
They were also used for light freight duties. This involved moving goods trains over shorter distances.
Retirement
These locomotives served British Rail for about ten to twelve years. They started to be retired from service in 1967. The last ones were taken out of service by 1969.
After retirement, most of these locomotives were scrapped. This means they were taken apart and their materials were recycled.
