LSWR H16 class

The LSWR H16 class were five 4-6-2T tank locomotives designed by Robert Urie for the London and South Western Railway (LSWR) in 1921–1922.

As part of the project to construct a marshalling yard at Feltham in West London, Urie produced two locomotive designs, the G16 "Black Tanks" to shunt the new yard, and the H16 "Green Tanks" to work transfer freights to the London area yards of the other railway companies.

On passing to the Southern Railway, they had their LSWR numbers prefixed with an 'E'.

Under the new locomotive classification system for constituent companies of the SR,[3] they were classified as G6/7/1+1⁄4 for Goods, Grade (hauling power), Power and Range (route availability).

[5] All five engines were passed to British Railways, who renumbered them 30516–30520.
