The DH class is a class of diesel-hydraulic locomotives built by Walkers Limited, Maryborough for Queensland Railways between 1966 and 1974.
In 1966, Queensland Railways tested a Walkers Limited built diesel-hydraulic shunting locomotive. This was later purchased and by 1974, the 73 DH class locomotives had taken over shunting duties in most Queensland yards. [1] They were also used on short-distance freight services. With the closure of many freight yards and the move to longer trains, withdrawals started in the 1980s. Many were sold for further use on Queensland sugar cane railways. [2] [3]
DH2 is retained by the Queensland Rail Heritage division. Privately owned DH71 is also on site.
DH14 was used at Old Ghan Heritage Railway and Museum, near Alice Springs, Northern Territory. Is stored due to trains not running.
In 1995, DH59 was purchased by the Puffing Billy Railway, which operates in Victoria. It was re-gauged to 762 mm (2 ft 6 in), reclassified as DH31, and is used as a replacement for steam locomotives on days of total fire ban. [4] It has since been joined by DH5.
As of 2017, DH31 is currently re-numbered back to its original DH59.
In 2010, the Walhalla Goldfields Railway in Victoria purchased DH37. The locomotive is stored on a section of 1,067 mm (3 ft 6 in) track in the Walhalla yard, awaiting re-gauging to the Walhalla Railway's 762 mm (2 ft 6 in) gauge. In June 2012, the Walhalla Goldfields Railway also bought DH72, which will also be stored until funds are available to re-gauge it to 762 mm. [5]
DH38 spent the majority of its working life in the Northern part of the state, especially around the Mackay area. Following a major failure – notably a large hole blown in the engine block following a crankcase explosion – the locomotive was withdrawn on 5 July 1991. After purchase by the ARHS Qld, DH38 underwent a major restoration involving rebuilding the engine and electrical system as well as having all axles and wheels replaced due to cracks.
Privately owned DH45 is currently leased, since 2015, to Southern Downs Steam Railway as a backup for SDSR's C17 steam locomotive. [6]
DH73 has been acquired by DownerEDi Marybrough to be used as a shunting locomotive. It is named Hugh Boge. [7] dead link

A geared steam locomotive is a type of steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design.
0-6-0 is the Whyte notation designation for steam locomotives with a wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles, and no trailing wheels. Historically, this was the most common wheel arrangement used on both tender and tank locomotives in versions with both inside and outside cylinders.
The Puffing Billy Railway is a 2 ft 6 in narrow gauge heritage railway in the southern foothills of the Dandenong Ranges in Melbourne, Australia. The railway was one of the five narrow gauge lines of the Victorian Railways which opened around the beginning of the 20th century. It is close to the city of Melbourne and is one of the most popular steam heritage railways in the world, attracting tourists from Australia and overseas. The railway aims to preserve and restore the line as near as possible to how it was in the first three decades of its existence, but with particular emphasis on the early 1920s.
The Walhalla Goldfields Railway is a 2 ft 6 in narrow gauge tourist railway located in the Thomson River and Stringers Creek valleys in Gippsland, Victoria, Australia, near the former gold-mining town and tourist destination of Walhalla.
The New Zealand DH class locomotive is a type of diesel-electric heavy transfer and shunting locomotive in New Zealand's national railway network. The class consists of six heavy shunt U10B type locomotives built by General Electric United States at their Erie, Pennsylvania plant in 1978. Five of the class are used in the Auckland area for heavy shunting duties, including services around Auckland and the Port of Auckland, while one is based at the Port of Tauranga in Mount Maunganui.
The rail network in Queensland, Australia, was the first in the world to adopt 1,067 mm narrow gauge for a main line, and, in 2013, was claimed to the second largest narrow gauge network in the world, consists of:
The former Victorian Railways, the state railway authority in Victoria, Australia, built a number of experimental 2 ft 6 in narrow-gauge lines around the beginning of the 20th century. Although all were closed by the early 1960s, parts of two have been reopened as heritage railways.
The Tyers Valley tramway was a 2 ft 6 in narrow-gauge timber tramway built by the Forests Commission of Victoria to exploit timber resources on the slopes of Mount Baw Baw, Victoria. At Collins Siding the tramway linked with the Victorian Railways' narrow-gauge line from Moe to Walhalla, and was built to the same 2 ft 6 in gauge.
Rail transport in Australia involves a number of narrow-gauge railways. In some states they formed the core statewide network, but in the others they were either a few government branch lines, or privately owned and operated branch lines, often for mining, logging or industrial use.
Walkers Limited was an Australian engineering company, based in Maryborough, Queensland. It built ships and railway locomotives. The Walkers factory still produces railway locomotives and rolling stock as part of Downer Rail.
The Victorian Railways G class is a class of steam locomotives built for the Victorian Railways 2 ft 6 in gauge branch lines by Beyer, Peacock & Company. They were introduced in 1926 to increase train sizes, eliminate the practice of double heading NA locomotives and reduce losses on these lines. Their tractive effort was comparable to the most powerful branch line locomotives on the Victorian Railways 5 ft 3 in, the K class.
The Victorian Railways NA class is a 2-6-2 tank locomotive built for their four 2 ft 6 in gauge branch lines.
The 73 class is a diesel-hydraulic locomotive built by Walkers Limited, Maryborough for the New South Wales Department of Railways between 1970 and 1973.
The W class are a diesel-hydraulic shunting locomotive ordered and operated by the Victorian Railways of Australia.
The GT42CU AC is a model of diesel electric locomotives manufactured by EDi Rail, Maryborough between 1999 and 2005 under licence from Electro-Motive Diesel, for use on narrow gauge railways in Queensland.
The Kamaishi Line is a 90.2 km (56.0 mi) rural railway line in Iwate Prefecture, Japan, operated by the East Japan Railway Company. It connects Hanamaki Station in the city of Hanamaki with Kamaishi Station in the city of Kamaishi.
The GT42CU ACe is a model of diesel electric locomotives manufactured by EDi Rail, Maryborough between 2007 and 2013 under licence from Electro-Motive Diesel, for use on narrow gauge railways in Queensland, South Australia and Western Australia.
The M/MA class are a class of diesel-hydraulic locomotives built by Walkers Limited, Maryborough for the Western Australian Government Railways in 1972–1973.
In the rail transport system of Bangladesh, diesel locomotives are used by Bangladesh Railway (BR). Among diesel locos, there are diesel-electric and diesel-hydraulic locos. Besides diesel locos, steam locos were used in the past, but now they are no longer used. By gauge, there are narrow-gauge (762 mm), meter-gauge (1,000 mm) and broad-gauge (1,676 mm) locos in Bangladesh. Among them, as no narrow-gauge railroads are active, so the narrow-gauge locos are not used anymore.
