History

The LBSCR Engineer Lawson Billinton in 1912 designed a new powerful goods locomotive that coped with heavy loads at speed. No 337 appeared the following year (1913) and by 1921 a total of 17 had been constructed at Brighton works. They proved to be very successful providing invaluable support during WW1 when very large freight movements were required.

The locomotives also coped well with passenger services providing a good all-round service to the railway. Billinton was not afraid to improve the steaming characteristics to help reduce coal running costs and the design innovations included an additional dome and top feed. This feature was improved and the last seven locomotives left Brighton works including this feature which lasted through to the end of the 1920’s before all were modified back to one dome.

More would have been built but for the fact that the LBSCR was merged into the larger SR in 1923 and the new company appointed a new Engineer Richard. E. L. Maunsell. He favoured his own N and U class designs so no more K Class locomotives were built.

In the 1930’s Maunsell improved the cab design and lowered the height as well as the dome and chimney to operate to the composite loading gauge.

Under BR ownership only minor changes were made. Removal of the LHS Weir Water Heaters in the early 1950’s and later modifications to the tender to include water treatment. Interestingly at the end of all their working lives the N and U designs cost far more to maintain with serious design faults in the frames and cylinders.

The K Class design proved reliable right to the end. One locomotive No 32353 was offered to the Bluebell Railway for preservation but unfortunately the society was struggling in 1962/3 to raise money to buy the track and infrastructure and could not afford the extra expense. (It is surprising the locomotive was not offered to the National Collection)

The LB&SCR K Class 2-6-0 steam locomotive was designed by Robert Billinton in 1912 for the London, Brighton and South Coast Railway. This powerful goods locomotive was capable of hauling heavy loads at speed and proved to be highly successful during World War I. A total of 17 locomotives were built at Brighton works between 1913 and 1921, with the design being improved over time to reduce coal running costs.

The locomotives also performed well on passenger services, providing a good all-round service to the railway. The design innovations included an additional dome and top feed, which was later modified back to a single dome in the 1920s. The LBSCR was merged into the Southern Railway in 1923, and the new company, under Engineer Richard E. L. Maunsell, favoured his own N and U class designs, resulting in no further K Class locomotives being built.

The K Class design was later modified by Maunsell in the 1930s, with improvements to the cab design and lowering of the height, dome, and chimney to operate within the composite loading gauge. Under British Railways ownership, minor changes were made, including the removal of the LHS Weir water heaters in the early 1950s and modifications to the tender to include water treatment.

The model of the LB&SCR K Class 2-6-0 steam locomotive, available exclusively from Rails of Sheffield, features detailed prototypical original and later body and tender details, including chimneys, domes, cabs, safety valves, Westinghouse pump, water heater, and AWS equipment. The model is equipped with a smooth 12V powerful motor, flywheel, and factory-fitted DCC sound sugar cube speaker. The model also features NEM couplings, hand-assembled detailing parts, and a fireman's shovel and firebox tools.
