The LNWR 18-inch Goods was a class of 310 0-6-0 freight steam locomotives built by the London and North Western Railway at their Crewe Works between 1880 and 1902.

[2] The design featured a boiler pressed to 150 lbf/in2 (1.03 MPa) delivering saturated steam to two 18 by 24 in (457 by 610 mm) cylinders connected by Joy valve gear to the driving wheels.

The dimensions quoted in the class title could be misleading: several locomotives ran for a period with 17-or-17+1⁄2-inch (432 or 444 mm) cylinders; and the “5ft 0in” referred to the diameter of the wheel centres – measured of the tyres the diameter was 5 ft 2+1⁄2 in (1,588 mm).

Two locomotives were withdrawn before the 1923 Grouping, leaving 308 to pass to the London, Midland and Scottish Railway, who gave them power classification 2F, and renumbered them 8315–8624.
