LSWR T3 class

The LSWR T3 class was a class of express passenger 4-4-0 steam locomotives designed for the London and South Western Railway by William Adams. Twenty were constructed between 1892–1893. The class were numbered 557–576, and had been intended as a variant of the X2 class with slightly smaller driving wheels (6 ft 7 in or 2.007 m versus 7 ft 1 in or 2.159 m). In reality, the coupled wheelbase was lengthened by 6 inches (150 mm) and the locomotive was fitted with a firebox 6 feet 10 inches (2.08 m) deep – the largest firebox of any of Adams' designs.
