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 locomotive was a powerful goods engine designed by Robert Billinton in 1912. Seventeen examples were built at Brighton works between 1913 and 1921, with the last seven featuring an additional dome and top feed. The locomotives proved to be highly successful, providing invaluable support during World War One and also performing well on passenger services.

In 1923, the LB&SCR was merged into the Southern Railway, and the new company's engineer, Richard Maunsell, favoured his own designs, resulting in no further K Class locomotives being built. Maunsell did, however, make improvements to the design in the 1930s, including lowering the height of the cab and dome, and modifying the loading gauge.

Under British Railways ownership, only minor changes were made to the locomotives, including the removal of the left-hand side Weir Water Heaters in the early 1950s and modifications to the tender to include water treatment. The K Class design proved reliable throughout its working life, but the N and U class designs, favoured by Maunsell, were found to have serious design faults in the frames and cylinders.

The model of the LB&SCR K Class 2-6-0 locomotive is a limited edition produced by Sonic Models, exclusively available from Rails of Sheffield. The model features a range of prototypical details, including chimneys, domes, cabs, safety valves, and Westinghouse pump, as well as AWS equipment and lamp/disc detail bracket variations. The model is powered by a smooth 12V motor with a flywheel and features a factory-fitted DCC sound system and a fully adjustable loco/tender linkage. The model's electrical pick-up is via all six driving and tender wheels, and it is packed in a strong outer box and mounted on a secure moulded transit plate to ensure safe transit.
