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.

No. 563 was retired in August 1945 and set aside for preservation. Its permanent home is the Shildon Locomotion Museum in England, but it was in Toronto, Ontario, from May to October, 2011, on loan for use in a theatrical production of The Railway Children at Roundhouse Park.
