The Victorian Railways X class was a mainline goods locomotive of the 2-8-2 'Mikado' type operated by the Victorian Railways (VR) between 1929 and 1960. They were the most powerful goods locomotive on the VR, aside from the single H class, H220, which was confined to the North East line, until the advent of diesel-electric traction, and operated over the key Bendigo, Wodonga, and Gippsland mainlines.
