Manufacturer description

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Withdrawn in November 1961, no preserved examples exist.

Prototype information

^* Class names often change over the lifespan of a locomotive, so this is not necessarily the class name used by the operator in the period modelled.

The Dapol SECR Maunsell D1 Class locomotive is a limited edition model produced by Dapol, available exclusively through Rails of Sheffield. This model represents locomotive No. 735, a member of the SECR Grey 4-4-0 steam locomotive class.

Built by Ashford Works and other manufacturers between 1901 and 1907, the D1 class was a significant upgrade to the earlier D class locomotives. The class was rebuilt between 1921 and 1927, with 21 D class locomotives being converted into the D1 class. The D1 class was designed to provide a considerable increase in haulage and power over its predecessors.

The model features a diecast chassis, low centre of gravity, and NEM couplings with a removable coupling pocket. It also includes sprung buffers, a powerful 5 pole motor, and a pull-out PCB for DCC and speaker fitting. Additionally, the model features a 'snap-fit' conductive tender drawbar, options for a bass reflex speaker, firebox glow, and profiled wheels.

The model will be available in various configurations, including two frame variations, two cab types, and multiple chimney, smokebox, and dome styles. The model will also feature different safety valve and lubricator options, as well as 'high capacity' tenders and manual and automatic lubricators.
