The 5101 class of large prairie locomotives were updated versions of the 3100 class and built between 1929 and 1939 which included the 6100 series, with a higher boiler pressure and designed for London suburban services. The final built between 1946 and 1949 with the last twenty not receiving Great Western livery.
During December 1965 the last eleven locomotives were withdrawn all being from the 6100 batch. Dapol shall be manufacturing these models from the early 1930’s when cab side shutters were added.
The locomotive has a diecast chassis with a five pole motor driving the rear wheel. To add compensation the centre driving wheels are sprung, the front pony truck is also sprung and operates on a cam so the model will negotiate R2 curves with ease.
The locomotive has electrical pick-up on all driving and tender wheels
