The London, Brighton and South Coast Railway E4 class is a class of 0-6-2T side tank steam locomotive designed by Robert Billinton. They were introduced in 1897 and were essentially a larger version of the E3 Class. The cylinder diameter was reduced from 18 to 17.5 inches (457 to 444 mm) by the Southern Railway.
