The WAGR E class were a class of 4-6-2 steam locomotives built for the Western Australian Government Railways (WAGR) by English manufacturers Nasmyth, Wilson & Co, Vulcan Foundry and North British Locomotive Company, from 1902. The locomotives provided a huge increase in locomotive power available to the WAGR and were the mainstay traction of WAGR passenger services for two decades. The Es class was the name given to a reconstruction of all but four of the class carried out between 1924 and 1925.
