Victorian Railways Y Class 0-6-0 Standard Locomotives comprised a group of 31 engines destined for mainline goods traffic. These were of impressive size for it's day, in fact no bigger 0-6-0 was ever built for an Australian railway. The initial pattern engine (# 445), named ' Victoria' was built to their own design by Kitson & Co Leeds Engineering England in 1887 and carried builder's number 3089. The remainder were built at Ballaarat by the Phoenix Foundry and given road numbers, in odd notation, 383 to 441 (builder's no. 220 - 249). The early activities of the class were generally restricted to mainline goods traffic, as the high axle loading precluded their use on the light lines which were generally laid with 60lb rails. These locomotives were fitted with two inside cylinders, 18in x 26in, the slide valves being actuated by Stephenson's valve gear. Each of the six coupled driving wheels measured 4ft 6in, with the axles equally spaced at 7ft 6in centres. Cast-iron sandboxes were mounted on the running plates adjacent to the smokebox and incorporated the leading splashers.
Boilers were frequently interchanged with the 'New A' class 4-4-0's and had a total heating surface of 1151.00 sq ft, of which the tubes contributed 1056.00 sq ft. The firebox of 95.00 sq ft had a fire grate area of 21.0 sq ft. The working boiler pressure was 140lbs, which gave a tractive effort of 17,472lbs. The 6 wheel tender which was standard on the 'New A', 'New R' and 'D' classes carried 10,001 litres of water and 70cwt of coal.
In 1890 they were allocated as follows: Melbourne (22), Ballaarat (8) and Bendigo (1). The Engines allocated to Ballaarat and Melbourne saw use on the Geelong, Ararat and Seymour Lines.
Numbers 387, 413 and 445 was used on contruction trains from 1889 to 1900
Troughout the years the class was used in many experiments, No.389 was fitted with a Knorr's feed water heater 1895~97, No.409 was fitted for Oil Burning 1904~1905, No.433 fitted with a Norwegian spark arrester 1895~96.
Some of the class where also involved in accidents, 413 ran into track laying equipment building the Outer Circle in 1889, 385 Derailed at North Geelong in 1895 and again with a collision into a ballast train at Fairfield 1900, 383 had a collision at Somerton 1890, 387 damaged in accident 1892, 395 in ballast train accident Fairfield 1900.
