WAGR E class
Upon the E classes' entry into service, they were an immediate success and from 1924 to 1925 most were superheated, becoming the Es class. In 1934 two E class locos had their weight reduced becoming the Ea class, and several more were converted while being superheated and classified Eas. The last E class was withdrawn in 1963. No. 308 is preserved at the Bassendean Railway Museum.
