The X class were built by [[Beyer, Peacock and Company|Beyer, Peacock & Coy]] of [[Manchester]], [[England]] and [[Metropolitan-Vickers]] of [[Stockton-on-Tees]], [[England]] from 1954 to 1956. Due to their light axle loads, they were immediately pressed into service around the entire network, they were allocated to express trains despite being designed for goods traffic. Their rigid frames made them rough riders, but because didn't require turning around they were still considered more efficient. The engine used in the X class initially was untested and had various faults, issues and problems causing severe reliability concerns with resulting failures causing a Royal Commission into the matter which recommended the complete replacement of the X class. [[Midland Railway Workshops]] managed to continually repair, alter, and rebuild the X class to make them serviceable. Some members of the class became the [[WAGR Xa class|Xa class]] due to being fitted with twin/dual air (vacuum) braking. Withdrawals of the X class started in 1973, with the X class relegated to working [[grain]] [[Train|trains]] on the [[South Western Railway (Western Australia)|South Western mainline]] in their dwindling years along with serving the [[Fremantle railway line, Perth|Fremantle to Perth section]] of the [[Eastern Railway (Western Australia)|Eastern Railway]] when it reopened. In 1988 the last of the X class was withdrawn. One of the X class is preserved on display at the [[Australian Railway Historical Society|ARHS]] [[Rail Heritage W.A.]] [[Bassendean Railway Museum]], and another five Xa class are also preserved.
