PLEASE NOTE THIS IS AN AS NEW MODEL WITH A DAMAGED BOX Exclusive Model, Produced by Dapol.

Brief History:

After 1901 the D class locomotive fast became the mainline locomotive of choice on the south coast, (making the SE&CR’s first mainline express formation) further (for the time) powerful locomotives were investigated by the companies. After Richard Maunsell took the reigns from Harry Wainwright in 1913 he worked on a series of new locomotives which were intended for a long service life, this involved the conversion and upgrade of 11 E class locomotives, resulting in the E1 class. This proved very successful and led directly to the conversion of 21 D class into the D1 class between 1921 and 1927. Though arguably, not as elegant as the D class equipped with a larger boiler, a belpaire firebox and longer travel cylinders the D1 was able to produce a considerable haulage and power increase over its predecessors.

Initially allocated to Ashford shed, this class was to be found all over the south-eastern division from London to the south.

Withdrawn in November 1961, no preserved examples exist.
