The W class are a diesel-hydraulic shunting locomotive ordered and operated by the Victorian Railways of Australia.
In mid 1957, the Victorian Railways called for tenders for a fleet of 25 diesel-hydraulic locomotives rated at 500 hp (370 kW). Tulloch, based in Rhodes, New South Wales, won the contract with an offer for West German-style locomotives, using a Mercedes V12 diesel engine developing 660 hp (490 kW) which was coupled to a Krupp 2W1D46 hydraulic transmission powering the centre axle, with the leading and trailing axles powered via connecting rods. All 25 engines entered service in the year from December 1959. [2]
Tulloch expected a repeat order for a further 25 units from the Victorian Railways, and also built a standard gauge version numbered 7101 as a demonstrator unit for the New South Wales Railways. However, the latter system rejected the design as unsuitable, so that unit was sold to the Victorian Railways and used for construction trains on the Albury NSW to Melbourne standard gauge line. After that project was completed, it became one of the standard gauge shunting units operating between South Dynon and Spencer Street station. The final engine, W267, had been built in anticipation of the repeat order that never eventuated - while the contract was written, it was never signed. [3] Instead, the final engine was converted to standard gauge and shared duties with W266.
Engines were fitted with controls on both sides of the centre console, although that feature was removed not long after delivery. [4] [5] The engines were initially rostered on local passenger services to Werribee and trialled on Bacchus Marsh runs, but with the low speed limit of 40 mph (65 km/h) and relatively little power, they were unable to keep to the timetable to the latter.
The engines proved incredibly unpopular, due to problems with ride quality and engine reliability, and a transmission change needed to achieve mainline running speeds. The high gear setting was removed early on and the class relegated to shunting duties in an attempt to better utilise the fleet. However, the cab profile made visibility a problem in yards, and engine crews had to lean out the side to observe shunting instructions. The cab design also provided no shelter from the weather in storms or on hot days. Common failures included seized transmissions, oil leaking onto the shunters' steps creating a slip hazard, and failed engine blocks. [6]
Between 1973 and 1977, at least ten engines, starting with W249, [7] had the Mercedes engine removed and replaced with General Motors diesel units. Engines after the first had different exhaust arrangements, but all those refitted could be identified externally by a second exhaust stack at the end of the long hood, with the original adjacent to the driving cabin plated over. [8] The alterations raised the engine hood by 208mm but did not replace the original transmission or gearbox. [9]
The class was generally allocated to Ballarat, Geelong and Melbourne for short shunting trips, and one each at Ararat, Bendigo and Seymour, explicitly for yard work only. However, on the odd occasion, Seymour-based W241 was used on the Shepparton goods, and also ran out to Rushworth and Colbinabbin. It also made it to Benalla a few times. [10]

The 71 class was a class of diesel locomotive operated by the New South Wales Department of Railways in Australia.
The locomotive was of the 0-6-0 wheel arrangement, fitted with a 12-cylinder Mercedes-Benz engine, Krupp hydraulic transmission and axle-gear and Behr hydraulic cooling equipment.
Having just completed 25 1,600 mm (5 ft 3 in)650 hp (480 kW) diesel-hydraulic shunting W class locomotives for the Victorian Railways, Tulloch Limited, with a view to receiving an order for similar units, offered the NSW Department of Railways a similar 1,435 mm (4 ft 8+1⁄2 in) standard gauge version in 1960 for a 12-month testing period. The offer was accepted and the unit was taken into service on 11 November 1960, numbered 7101. Although allocated to Delec Locomotive Depot, all servicing was done at Tulloch Limited. No. 7101 was used on local transfer and shunting trips in the Sydney metropolitan area. It operated under conditions similar to the 70-class then in operation.
In mid-1961, Tulloch Limited was experiencing operating difficulties and was unable to fulfil its obligations in regard to the hiring. 7101 was returned on 21 June 1961 and sold to Victorian Railways, who used the locomotive from 4 July on the construction of the North East standard gauge line between Albury and Melbourne. [11] It was repainted in the same colours as the 25 broad gauge units and renumbered W266. [12]

A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.
The British Rail Class 52 is a class of 74 Type 4 diesel-hydraulic locomotives built for the Western Region of British Railways between 1961 and 1964. All were given two-word names, the first word being "Western" and thus the type became known as Westerns. They were also known as Wizzos and Thousands. The final Class 52 locomotives were withdrawn from service in 1977.
The Yorkshire Engine Company Janus is a line of 0-6-0 wheel arrangement, diesel-electric locomotives that weighed 48 long tons and had a maximum speed of 23 mph (37 km/h). The two Rolls-Royce C6SFL diesel engines gave a total power output of 400 hp (300 kW). Each engine had its cooling system at the outer end, and its generator at the inner end. There were two traction motors, each being powered by one generator, thus simplifying the electrical system.
The EMD G8 is a model of diesel-electric locomotive of which 382 were built between 1954 and 1965 for both export and domestic use. They were built by both Electro-Motive Division in the United States and by General Motors Diesel Division in Canada for use in ten countries, being equipped to operate on several different track gauges.
The N class was a branch line steam locomotive that ran on the Victorian Railways (VR) from 1925 to 1966. A development of the successful K class 2-8-0, it was the first VR locomotive class designed for possible conversion from 5 ft 3 in to 4 ft 8+1⁄2 instandard gauge.
The Victorian Railways J class was a branch line steam locomotive operated by the Victorian Railways (VR) between 1954 and 1972. A development of the successful Victorian Railways K class 2-8-0, it was the last new class of steam locomotive introduced on the VR. Introduced almost concurrently with the diesel-electric locomotives that ultimately superseded them, the locomotives were only in service for a relatively short time.
The railways of New South Wales, Australia, use a large variety of passenger and freight rolling stock. The first railway in Sydney was opened in 1855 between Sydney and Granville, now a suburb of Sydney but then a major agricultural centre. The railway formed the basis of the New South Wales Government Railways. Passenger and freight services were operated from the beginning. By 1880, there was a half hourly service to Homebush.
The C Class are a class of diesel locomotive built by Clyde Engineering, Rosewater for the Victorian Railways in 1977–1978.
German Kleinlokomotiven like the DRG Kö II were developed as locomotives with a low weight and driving power for light shunting duties. There were two classes, based on engine power. The Class II were engines which developed more than 40 HP.
Gmeinder GmbH was a German locomotive and engineering company based in Mosbach. Its products included diesel engines, small locomotives (shunters) and other railway locomotive parts. Much of its business came through the German railways, though it also exported to the rest of Europe and the rest of the world.
A Kleinlokomotive or Kleinlok is a German locomotive of small size and low power for light shunting duties at railway stations and on industrial railways. Most are powered by diesel engines, but Kleinloks with steam, petrol, or electric engines were also produced.
The Victorian Railways M class are a diesel-hydraulic powered railway shunting locomotive, based at the Newport workshops of the Victorian Railways in Victoria, Australia.
The China Railways DFH1 was a type of 4-axle B'B' single-cab diesel-hydraulic locomotive used on mainline passenger services; the DFH3 was a later development of a similar design but with two driving cabs.
The China Railways "Dongfang Hong" diesel-hydraulic locomotive classes DFH2, DFH5, DFH6, and DFH7, built from the 1970s to 1990s, were all used as shunters on the Chinese railway network.
The BHP Newcastle 37 class were a class of diesel locomotives built by A Goninan & Co, Broadmeadow for the BHP's, Newcastle Steelworks between 1960 and 1983.
The South African Railways Class 61-000 of 1959 was a diesel-hydraulic locomotive.
Tulloch Limited was an Australian engineering and railway rolling stock manufacturer, located at Rhodes, New South Wales.
The 400/500 class rail motors are diesel trains built by New South Wales Government Railways primarily for use on regional lines throughout NSW. The trains have since been phased out following a rationalisation of country branch line rail services in November 1983. The 400 Class power cars were built in 1938 at the Eveleigh Carriage Workshops, while the 500 Class trailer cars were built by Ritchie Brothers at Auburn.
The South Maitland Railways railcar was a class of diesel railcar built by Tulloch Limited for the South Maitland Railway (SMR) in 1961.
The class WDS-3 was a diesel-hydraulic locomotive used by Indian Railways for shunting and doing departmental works. The model name stands for broad gauge (W), diesel (D), shunting (S) 3rd generation (3). The WDS-3 is used mostly in the Northern Railway Zone (NR). All these locomotives were withdrawn and scrapped by the late 1990s.
