LB&SCR K Class 2-6-0 LBSC Black No.346 Unlined Steam Locomotive

History

The LBSCR Engineer Robert 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)
