The Western Australian Government Railways L-Class were designed as an Australian version of the US SD40 model. They emerged from the Clyde Engineering plant at Sydney between 1967 and 1969. 23 were initially built, followed by an extra two for Western Mining in 1973. In 1972, two similar locos were built for Comalco's railway at Weipa on Cape York Peninsula. These were not fitted with dynamic brakes, and weighed 148 tonnes. The WAGR fleet were purchased to operate the new standard gauge railway from Perth to Kalgoorlie, which replaced the narrow gauge route in 1970.

Today, the L-Class operate industrial and general freight traffic in WA, with three operating in NSW for grain traffic. They are prefixed L, LQ (QTRAC traction control) or LZ (ZTR traction control).
