NZR WF Class
The NZR WF class were steam locomotives designed, built and used by New Zealand Railways (NZR). Their wheel arrangement is described by the Whyte notation 2-6-4T and the first members of the class entered service in 1904. The locomotives were tank engines designed by the Railways Department's Chief Mechanical Engineer A. L. Beattie, and were mainly built for suburban duties such as those between Christchurch and Lyttelton. They also saw main-line service in the Taranaki region, but most of the class members were assigned to branch line and local services throughout the country. Two were experimentally converted to oil burners in 1909-1910. The tests were satisfactory, but as coal was much cheaper than oil at the time, no further conversions took place. There were 41 in the class; built by Addington Workshops (10), Hillside Workshops (16), and A & G Price of Thames (15). Construction and design In 1902, a drawing was made showing a 2-6-4T tank locomotive, based on a propos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NZR WA Class
The NZR WA class locomotives were a class of Tank locomotive built by New Zealand Railways (NZR). Eleven were built at NZR's own Addington Workshops in Christchurch and Hillside Workshops in Dunedin. Four more were converted from old J class 2-6-0 locomotives. Three were fitted with brakes to assist descent on the Fell-operated Rewanui and Roa inclines on the South Island's West Coast Region. These were among the last in use. Preservation Only one WA class has been preserved, number 165. The locomotive was restored by Gisborne City Vintage Railway in 2000.

New Zealand Railways Department
The New Zealand Railways Department, NZR or NZGR (New Zealand Government Railways) and often known as the "Railways", was a government department charged with owning and maintaining New Zealand's railway infrastructure and operating the railway system. The Department was created in 1880 and was corporatised on 1 April 1982 into the New Zealand Railways Corporation. Originally, railway construction and operation took place under the auspices of the former provincial governments and some private railways, before all of the provincial operations came under the central Public Works Department. The role of operating the rail network was subsequently separated from that of the network's construction. From 1895 to 1993 there was a responsible Minister, the Minister of Railways. He was often also the Minister of Public Works. Apart from four brief experiments with independent boards, NZR remained under direct ministerial control for most of its history.

Lyttelton, New Zealand
Lyttelton (Māori: ''Ōhinehou'') is a port town on the north shore of Lyttelton Harbour / Whakaraupō, at the northwestern end of Banks Peninsula and close to Christchurch, on the eastern coast of the South Island of New Zealand. As a landing point for Christchurch-bound seafarers, Lyttelton has historically been regarded as the "Gateway to Canterbury" for colonial settlers. Until the 2020 coronavirus pandemic, the port has been a regular destination for cruise ships. It is the South Island's principal goods-transport terminal, handling 34% of exports and 61% of imports by value. In 2009 Lyttelton was awarded Category I Historic Area status by the Historic Places Trust (NZHPT) defined as "an area of special or outstanding historical or cultural heritage significance or value", not long before much of the historic fabric was destroyed in the 2011 Christchurch earthquake. Location Lyttelton is the largest settlement on Lyttelton Harbour / Whakaraupō, an inlet on the northwes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emu Bay Railway
The Emu Bay Railway was a Tasmania, Australian railway company. The railway was significant during full operation, in that it linked the Tasmanian Government Railways system at Burnie with that at Zeehan that further linked to the Mount Lyell railway allowing connection through to Queenstown. It was listed on the Melbourne Stock Exchange. Following the closure of the Tasmanian government line at Zeehan railway station in 1960, until 1965, it operated the Melba Line on the West Coast of Tasmania following the closure of the Zeehan section until 1998. History The origins of the Emu Bay Railway can be traced back to February 1878 when the Van Diemen's Land Company opened a 71 kilometre, horse drawn wooden tramway line from Emu Bay (Burnie) to Rouse's Camp, near Waratah, to serve the Mount Bischoff tin mines. The line was surveyed by John C Climie. In 1887, the line was taken over by the Emu Bay to Mount Bischoff Railway Company and relaid with steel rails as a gauge ra ...

Tasmanian Rail News
The Australian Railway Historical Society (ARHS) aims to foster an interest in the railways, and record and preserve many facets of railway operations. It had divisions in every state and the Australian Capital Territory, although the ACT division was wound up in 2016, along with the Victorian division in 2020. Since 1967, when each division incorporated, the state divisions have operated as separate entities. Each still trades under the ARHS brand, except in Western Australia, where the division is called Rail Heritage WA. Individual membership exceeds 2,500. Background The ARHS was founded in Sydney in 1933 as The Railway Circle, becoming the Australasian Railway and Locomotive Historical Society shortly afterwards. The society's name was changed to the present form in 1952. Divisions were later formed in most states, most of which established a railway museum, namely: *ACT - Canberra Railway Museum, Kingston *Queensland - Rosewood Railway Museum *South Australia - SteamRan ...

NZR EC Class
The NZR EC class was a class of electric locomotive used in Christchurch, New Zealand. They replaced steam locomotives on trains through the Lyttelton rail tunnel between Lyttelton and Christchurch. Introduction Since its opening in 1867, the Christchurch to Lyttelton line had become extremely busy with both suburban and goods trains passing through the Lyttelton Tunnel, which had been opened in 1867. Smoke accumulating in the tunnel from each successive train became a nuisance for train crews and passengers travelling through the tunnel. Although trials were conducted in 1909 using steam locomotive WF 436 which had been converted to oil firing, the cost of oil alone meant that no further work was done. In 1925, the English consultancy of Merz & McLellan was commissioned by then Minister of Railways, Gordon Coates, to report on electrifying the suburban networks in Auckland, Wellington, Christchurch and Dunedin. The report, released in August 1925, recommended that of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walschaerts Valve Gear
The Walschaerts valve gear is a type of valve gear used to regulate the flow of steam to the pistons in steam locomotives, invented by Belgian railway engineer Egide Walschaerts in 1844. The gear is sometimes named without the final "s", since it was incorrectly patented under that name. It was extensively used in steam locomotives from the late 19th century until the end of the steam era. History The Walschaerts valve gear was slow to gain popularity. The Stephenson valve gear remained the most commonly used valve gear on 19th-century locomotives. However, the Walschaerts valve gear had the advantage that it could be mounted entirely on the outside of the locomotives, leaving the space between the frames clear and allowing easy access for service and adjustment, which resulted in it being adopted in some articulated locomotives. The first locomotive fitted with the Walschaerts valve gear was built at the Belgian Tubize workshops, and was awarded a gold medal at the 1873 Univ ...

Stephenson Link Motion
The Stephenson valve gear or Stephenson link or shifting link is a simple design of valve gear that was widely used throughout the world for various kinds of steam engines. It is named after Robert Stephenson but was invented by his employees. Historical background During the 1830s, the most popular valve drive for steam locomotives was known as '' gab motion'' in the United Kingdom and'' V-hook motion'' in the United States. The gab motion incorporated two sets of eccentrics and rods for each cylinder; one eccentric was set to give forward and the other backwards motion to the engine and one or the other could accordingly engage with a pin driving the distribution valve by means of the gabs: - vee-shaped ends to the eccentric rods supposed to catch the rocker driving the valve rod whatever its position. It was a clumsy mechanism, difficult to operate, and only gave fixed valve events. In 1841, two employees of Robert Stephenson and Company, draughtsman William Howe and ...

Tractive Effort
As used in mechanical engineering, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total traction that is parallel to the direction of motion. In railway engineering, the term tractive effort is often used synonymously with tractive force to describe the pulling or pushing capability of a locomotive. In automotive engineering, the terms are distinctive: tractive effort is generally higher than tractive force by the amount of rolling resistance present, and both terms are higher than the amount of drawbar pull by the total resistance present (including air resistance and grade). The published tractive force value for any vehicle may be theoretical—that is, calculated from known or implied mechanical properties—or obtained via testing under controlled conditions. The discussion herein covers the term's usage in mechanical applications in which the final stage of the power transmission system is ...
