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.^[1][2][3] The first six (XR550 - XR555) were converted from X38, X35, X40, X33, X34 and X32 respectively. A seventh (XR556) was planned to be converted from X36 but never eventuated.^[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.^[5][6] As at October 2022, all nine were active, seven on the broad gauge and two (XR558 and XR559) on standard gauge. As of November 2024 all are on BG except XR555 (Stored) & XR559 ^[7]

The class are mechanically similar to the later XRB class B units.^[4]
