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 locomotives were 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 During December 1965 the last eleven locomotives were withdrawn all being from the 6100 batch.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 has now added extra tooling to allow us to model all variants of these locomotives.
