Victorian Railways O class

The Victorian Railways O class was a class of 0-6-0 goods locomotives operated by the Victorian Railways between 1862 and 1922, built by various builders. The first order was placed in April 1861 with Slaughter, Gruning and Company for six locomotives, and in January 1862 for twelve locomotives with Robert Stephenson and Company, whose engines arrived in October 1862. Later orders went to Beyer, Peacock and Company and the Yorkshire Engine Company, and seven were built locally by the Phoenix Foundry of Ballarat and two by the Victorian Railways at Williamstown Workshops. The locomotives were allocated to Class O in 1886 and were reboilered to raise the working pressure to 140 and then 160 psi, and the remainder were withdrawn between 1904 and 1921, some being used as stationary engines at the Newport Workshops.
