History
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.Here & There Australian Railway History issue 774 April 2002 page 154X class rebuilding project Railway Digest October 2003 pages 29-32Locomotive Upgrading by the Operator Railway Digest July 2004 page 39 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.{{cite book|last=Oberg|first=Leon|title=Locomotives of Australia 1850s - 2010|date=2010|publisher=Rosenberg Publishing|isbn=9781921719011|page=345}}
A further three (XR557 - XR559) were built in 2004/05 by Freight Australia's successor, Pacific National, as new-builds.
In 2020, several were placed in storage due to a poor grain harvest.Four stored XR Class locos moved - two for further storage and two for reactivation Newsrail September 2020 page 255MotivePower Roundup Motive Power issue 133 January 2021 page 116 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 Australia Wide Fleet List Motive Power issue 144 November 2022 page 69
The class are mechanically similar to the later XRB class B units.
