Victorian Railways S Class (diesel)

The S class are a class of diesel locomotives built by Clyde Engineering, Granville for the Victorian Railways between 1957 and 1961.

History

The S class was based on the Electro-Motive Diesel F7 design and were very similar to the GM12 class then being built by Clyde Engineering for the Commonwealth Railways. They were mechanically similar to the 1952 built double ended B class.

The first order for 10 locomotives were progressively delivered between August 1957 and February 1958. The first four took the names and numbers of the recently scrapped S class steam locomotives, with all being named after prominent Victorians. An additional eight locomotives were ordered for use on the new North East standard gauge line and delivered between November 1960 and December 1961.

The class were initially used on express passenger trains such as the '' Intercapital Daylight'', ''Southern Aurora'', ''Spirit of Progress'' and ''The Overland'', but were also used on fast freights. On the broad gauge, they often operated in pairs, while on the standard gauge they usually ran solo.S class diesel electric locomotives

In February 1969, two were destroyed in the Violet Town railway disaster, and were deemed uneconomical to repair and scrapped. In January 1967 S317 was badly damaged in a head-on collision with X33 south of Broadford Loop and was returned to Clyde Engineering for rebuilding. In June 1982, S317 was again involved in a fatal accident when it ran into the rear of the ''Spirit of Progress'' at Barnawartha, killing the crew.

As more modern locomotives were introduced, those on the standard gauge moved to the broad gauge. Examples would periodically appear on the standard gauge.

When the G Class engines entered service, the railways declared that no more S Class engines would undergo major overhauls. The last two had been S301 in 1985 and S307 in 1986; as of July 1987, engines S303, 304, 305 and 309 were withdrawn, 308 banned as a leading unit and 306 was under minor repair but still in the VR Blue livery. In February 1994, four (300, 302, 311, 312) were sold to West Coast Railway for use on their Melbourne to Warrnambool passenger service. By April 1999, only four remained in the V/Line fleet and even these were only used during periods of high demand. A few have been preserved.

Privatisation brought an upturn in the class' fortunes with some overhauled and as at May 2014, they remain in service with CFCL Australia, Pacific National and Southern Shorthaul Railroad. In 2019, S300 and S311 were purchased privately from CFCLA. S311 was purchased from its private owner by SSR in mid 2020 and was promptly returned to service, still on standard gauge operating primarily in NSW. Pacific National donated S307 to the Seymour Railway Heritage Centre on 17 March 2023. Pacific National donated S301 to Steamrail Victoria on 7th March 2024, and it is now used on heritage operations.
