In 1968, Commonwealth Railways (CR) placed an order for five 2237kW locomotives with Clyde Engineering to operate services on the Trans-Australian Railway from Port Pirie to Kalgoorlie. The first locomotive was completed in January 1970. CR placed two additional orders to result in a total of 17 CL Class locomotives being built, CL17 being delivered to CR in October of 1972.

In 1992, Australian National (AN) awarded a contract to Morrison-Knudsen Australia (MKA) to rebuild all of the CL Class Locomotives to two different versions of locomotive. Seven CLs were rebuilt into CLF Class Locomotives, and the remaining ten were rebuilt into CLP Class Locomotives.

The CLF and CLP Classes were rebuilt as 3,300hp locomotives, with an EMD V16-645E3C engine. Their starting tractive effort is 98,700lbs, with a continuous tractive effort of 60,634lbs at 14.9mph.

In mid 2019, the private operator known as Southern Shorthaul Railroad had purchased 4 locomotives; these being CLF1, CLF3, CLP9 and CLP12. They were all in service by 2023.
