The Y class are a class of diesel locomotives built by Clyde Engineering, Granville for the Victorian Railways between 1963 and 1968.


In 1963 the first of 25 diesel shunters was delivered by Clyde Engineering. Two further orders saw the class total 75 by 1968. Although built to dieselise Victoria's shunting operations. they were also used on mainline freight and passenger services including between Spencer Street and Werribee.[1]

After closure of branch lines across the state and the end of short pick-up goods trains, use of the class dropped.[2]

In the 1980's it is thought that four Y Class locomotives were on standard gauge, typically no's 101-104.

Withdrawals commenced from 1985 and large-scale scrappings commenced during 1991 and 1992.[2]

After the mass-withdrawls of the Y fleet up to 1992, engines 101, 102, 104, 150 and 151 were on standard gauge, as 103 had been withdrawn in the late 1980's. Y101 followed in the early 90's after suffering a collision, but it was not directly replaced.

From 1995, under the newly formed V/Line Freight division, engines Y115, Y151, Y152 and Y169 were running trains on standard gauge, and locomotives Y124 and Y142 were confined to shunting at South Dynon. Within a few years Y150 had replaced Y115 on standard gauge, with the latter engine shifting to Ballarat as a yard pilot. Around the same time, Y169 replaced Y102, and Y152 replaced Y104. These two engines were stored at Newport workshops, then transferred to South Dynon's "rotten row" where they sat for about a decade.

Today four are in service with V/Line as carriage yard shunters, with others owned by freight operator Pacific National.[3][4][5]
