- The SECR N class was a type of 2-6-0 ("mogul") steam locomotive designed in 1914 by Richard Maunsell for mixed-traffic duties on the South Eastern and Chatham Railway (SECR). Built between 1917 and 1934, it was the first non-Great Western Railway (GWR) type to use and improve upon the basic design principles established by GWR Chief Mechanical Engineer (CME) George Jackson Churchward. The N class was based on the GWR 4300 Class design, improved with Midland Railway concepts. The N class was mechanically similar to the SECR K class 2-6-4 passenger tank engine, also by Maunsell. It influenced future 2-6-0 development in Britain and provided the basis for the 3 cylinder N1 class of 1922. Production was delayed by the outbreak of the First World War in 1914, and the first N class rolled out of Ashford Works in 1917, three years after design work was completed. The class replaced obsolete 0-6-0s as part of the SECR's fleet standardisation, as they used parts interchangeable with those of other classes. Eighty N class locomotives were built in three batches between the First and Second World Wars. Fifty were assembled from kits of parts made at the Royal Arsenal, Woolwich, giving rise to the nickname of "Woolworths". They worked over most of the Southern Railway (SR) network, and were used by the Southern Region of British Railways (BR) until the last was withdrawn in 1966. One N class locomotive is preserved on the Swanage Railway in Dorset, undergoing overhaul. (en)
- La SECR classe N era una locomotiva a vapore di tipo "Mogul" progettata nel 1914 da Richard Maunsell per trasporto misto sulla South Eastern and Chatham Railway (SECR). Costruita tra il 1917 e il 1934, è stato il primo tipo di locomotiva non-Great Western Railway (GWR) a utilizzare e migliorare i principi costruttivi sviluppati da George Jackson Churchward, il capo ingegnere meccanico della GWR. La classe N era basata sul progetto della GWR classe 4300, migliorato con alcune caratteristiche della Midland Railway. Simile da un punto di vista meccanico alla precedente Classe K pure progettata da Maunsell, la Classe N ha a sua volta influenzato lo sviluppo di locomotive dello stesso tipo nel Regno Unito.La produzione, ritardata dallo scoppio della prima guerra mondiale, tra le due guerre è stata di 131 locomotive in tutto. Dalla sua introduzione nel 1917 la classe N è stata utilizzata per il trasporto sia merci che passeggeri sulla SECR.Ritenuta affidabile e robusta, presentava tuttavia l'inconveniente di eccessive vibrazioni sotto sforzo. Le locomotive classe N furono usate estensivamente dalle ferrovie britanniche, tanto che a 29 fu necessario cambiare il cilindro. L'elettrificazione delle linee portò a una graduale sostituzione di queste locomotive a vapore nella prima metà degli anni sessanta del Novecento. L'ultimo esemplare è stato ritirato nel 1966. L'unica locomotiva classe N ancora esistente, la n. 31874, sulla Mid Hants Railway, aprile 1978 (it)
