The SECR N class was a steam locomotive designed by Richard Maunsell for mixed-traffic duties on the South Eastern and Chatham Railway (SECR) in London and south-east England. This locomotive class, with two leading wheels and no trailing wheels (2-6-0), was mechanically similar to the SECR K class 2-6-4 passenger tank engine, also by Maunsell. Built at Ashford Works and the Royal Arsenal, Woolwich, between 1917 and 1934, the N class was based on the GWR 4300 Class design, improved with Midland Railway concepts. The class replaced obsolete 0-6-0s as part of the SECR's fleet standardisation, using parts interchangeable with those of other classes. Eighty N class locomotives were built in three batches between the First and Second World Wars. They worked over most of the Southern Railway network, and were used by the Southern Region of British Railways until the last was withdrawn in 1966. One locomotive is preserved on the Swanage Railway in Dorset, undergoing overhaul.
