The XR class are a class of diesel locomotives built by Pacific National at South Dynon Locomotive Depot.

Between 2002 and 2006, Pacific National rebuilt six X class locomotives with engines cascaded from G class locomotives, larger radiators, and a new cab to provide better driver visibility.

[4] A further three (XR557 - XR559) were built in 2004/05 by Freight Australia's successor, Pacific National, as new-builds.

[4] In 2020, several were placed in storage due to a poor grain harvest.
