The BR class 28 was a diesel - electric general-purpose locomotive.
History and technology
The locomotives of this series were classified as Type 2 locomotives according to their performance . The wheel arrangement of the locomotives supplied by Metropolitan Vickers was unusual . One bogie had three axles, the other two. The diesel engine was a Crossley - two-strokes with a patented exhaust gas pressure charging system. The exhaust gases escaping at high pressure should increase the pressure of the incoming fresh air.
The 20 locomotives drove out of Barrow-in-Furness for almost their entire service life .
It was not so much the asymmetrical Co'Bo 'wheel arrangement, but rather the technical problems of the Crossley two-stroke diesel engine that caused the Metropolitan Vickers Type 2 to be retired early. The use of the Metropolitan Vickers Type 2 locomotives ended by 1968 and by 1969 all but one of the locomotives had been scrapped.
The D5705 has been preserved as a museum.
Others
The locomotives were painted in the so-called "Brunswick green". The bogies were painted silver gray.
