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.

History

Victorian Railways initially numbered passenger and goods locomotives separately, the engines were delivered with numbers 26–31, 52–63, 70–81, 88–89. This system was changed before these locos entered service to odd numbers for goods locomotives and even numbers for passenger locos with these locomotives taking the odd numbers 19–81, 127–149. This odd and even system remained in use until 1912. In 1886, they were allocated to Class O.

Production

The first order for six locomotives was placed with Slaughter, Gruning & Co. (builder's numbers 460–465) in April 1861 and twelve locomotives with Robert Stephenson & Company (B/n 1441–1452) in January 1862. The locomotives built by Slaughter, Grüning (B/n 231–237, 261–266) arrived in Port Phillip June 1862, and the Robert Stephenson ones in October 1862.
In June 1865, an order for six more locomotives was placed with Beyer, Peacock & Company (B/n 553–558) which arrived May 1966. In 1870, a further order for six more locomotives was placed with Yorkshire Engine Company (B/n 153–158) which arrived March 1971. The last imports were ordered from Beyer Peacock, two in July 1871 (B/n 1040–1041) and three in 1878 (B/n 1709–1711). The imported locos had an average cost of £3919-14-10 for each.
Seven locomotives were locally built by the Phoenix Foundry of Ballarat in 1878/9 (B/n 48–54) and a further two by the Victorian Railways at the Williamstown Workshops in 1879 and 1881 at an average cost of £4142-15-0 for each local loco.

Regular service

Before entering regular service, O129 was exhibited at the Melbourne International Exhibition in 1880.
In 1894, they were allocated; ten at Melbourne; fourteen at Bendigo; ten at Ballarat and ten at Benalla.

Design improvements

Over the years they were fitted with various alterations to the cabs. There were also various upgrades over the years; with constant improvements to safety — these including things like updates to safety valves (and domes), smokeboxs and chimneys (with spark arrestors), cowcatchers, and brakes.
There were subsequent reboilerings which raised the working pressure to 140 psi (970 kPa) then to 160 psi (1,100 kPa), while their cylinder bore was increased from 17 to 17.5 inches (430 to 440 mm) when rebuilt after 1896. These changes led to considerably increased tractive effort.

Demise

Some were used as a stationary engines at Newport Workshops; O31 from 24 December 1908, five (O35, O39, O41, O53, O61) from 19 May 1909, and finally the boiler from O149 was used in a forge at Newport from 21 August 1916.
In 1912, O57's frames were sold to Mr Freeman of Echuca for £423, while it's tender was sold to Kerang & Koondrook Tramway for £60. On 19 May 1909, O63 converted to stationary engine and sold to Mr Arbuthnott of Koondrook (along with the boiler of R173) and was used in PS Arbuthnot.
.
The remainder were withdrawn between 1904 and 1921.
An unknown boiler from either a O or B class was used until 1941 to power refrigeration plant at Spencer Street where ice was made for T vans.
