The government was able to renegotiate the contract, with only twenty built. Ten were taken by the Commonwealth Railways as the L class, with the other ten going to the South Australian Railways as the 740 class after being converted for broad gauge operation. The 740 class remained in service until the early 1960s when replaced by diesels. The last was condemned in November 1965.[1]
