The British Rail Class 02 were a class of twenty 0-4-0 diesel-hydraulic shunting locomotives built by the Yorkshire Engine Company in 1960 (first ten, D2850-D2859) and 1961 (D2860-D2869) for service in areas of restricted loading gauge and curvature such as docks. They had the door to the cab at the rear, with a railed veranda behind the cab; this feature was unique to the Class 02 in the United Kingdom, although this layout is common in North American practice.
With the changes in the role of the British railway system and the closing of many of the facilities in which the Class 02 locomotives worked, they were increasingly surplus to requirements. The first locomotive was withdrawn from service in 1969 and the last one in 1973. Only three survived long enough to enter the BR TOPS computer system: 02 001 (formerly D2851), 02 003 (D2853), and 02 004 (D2856). Being only nine to fourteen years old when withdrawn, they still had a lot of life left in them, and the majority were sold to private industry. A large number (at least seven) are now in preservation, where their small size makes them perfect as a workshop shunter or for use in track maintenance work. One (D2860) is the works shunter for the National Railway Museum in York, where it is used to move much larger exhibits around.
In addition to these locomotives produced for British Railways, a good number of very similar locomotives were produced for industrial customers. Many of these can now be found in preservation also, since few industrial users have their own railways anymore. Quite a few are dressed up in ficticious British Railways livery and numbering.
The engine was a Rolls-Royce C6MFL176 6-cyl. in-line connected to a Rolls-Royce series 10,000 3-stage twin-disc torque converter and a manually operated YEC reduction and reversing final drive gearbox.
