The North Staffordshire Railway (NSR) New L Class was a class of 0-6-2T steam locomotives 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between 1908 and 1923, with the final four constructed under the auspices of the newly formed LMS with the whole class withdrawn by the end of 1937. There is one survivor.

The North Staffordshire Railway (NSR) was a British railway company formed in 1845 to promote a number of lines in the Staffordshire Potteries and surrounding areas in Staffordshire, Cheshire, Derbyshire and Shropshire.
