The LSWR X2 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 at Nine Elms Locomotive Works between 1890 and 1892.

The class were numbered 577–596, and were an enlarged version of the 460 class. Adams had designed his 7-foot-1-inch (2.159 m) drivered locomotives for the London to Bournemouth route, while the 6-foot-7-inch (2.007 m) drivered locomotives were intended for the London to Salisbury route which had more severe gradients.
