The North Staffordshire Railway (NSR) New L Class was a class of 0-6-2 steam locomotive designed by John H. Adams, third son of William Adams. They were designed as a development as the previous L Class, adding a boiler common to the M Class and differed from the L Class with, amongst other things higher bunker sides and new cab roofs, and the abandonment of the cast safety valve cover. 28 were built between 1908 and 1923, with the final four constructed under the auspices of the newly formed LMS.

All were withdrawn by the end of 1937; one was sold to the Longmoor Military Railway whilst four more were sold to Manchester Collieries Ltd. The rest were scrapped. NSR 2 was one of the locomotives sold to the Manchester Collieries Ltd and worked at Walkden where it received the name Princess. It was eventually rebuilt with a new saturated boiler and new tanks, bunker and cylinders in 1946.

It was subsequently saved for preservation by being placed in the Staffordshire County Council Museum at Shugborough Hall. In 1984 it was moved to Chatterley Whitfield Mining Museum, and at some point, it moved into the National collection. In April 2016 the National Railway Museum gifted the locomotive to the Foxfield Railway.
