South Australian Railways K Class (broad Gauge)
Eighteen South Australian Railways K class (broad-gauge) locomotives were built by Beyer, Peacock and Company for the South Australian Railways (SAR) between 1878 and 1884. Despite having a fundamental design flaw that affected their original role as light-line passenger locomotives, they eventually performed switcher, shunting duties exclusively. They operated for six decades. Need At a time of fierce competition between the Australian colonies, a Morgan railway line, railway line was extended from Kapunda to Morgan, South Australia, MorganThen known as North West Bend. on the Murray River, River Murray, opening in 1878. The link allowed goods brought downstream on riverboats from New South Wales and Victoria (Australia), Victoria to reach Port Adelaide for export more quickly and safely than by continuing on the river to the sea, since Morgan was only by rail to Adelaide but to the mouth of the river. Until the spread of other railway lines cut out most of the river traffic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. ...

0-6-4
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of no leading wheels, six powered and coupled driving wheels on three axles, and four trailing wheels on two axles. Overview The 0-6-4 wheel arrangement appears to have only been used on tank engines and Single Fairlies. The earliest known example was the Moel Tryfan narrow gauge locomotive, built for use on the North Wales Narrow Gauge Railways. It was a Single Fairlie type, built by the Vulcan Foundry near Manchester in 1875. It was followed by the R class and S class, built by the Avonside Engine Company of England for the New Zealand Railways Department between 1878 and 1881. Usage Australia The South Australian Railways K class locomotives were introduced in 1884, designed by William Thow. They were noted to run more smoothly bunker-first. After the electrification of the Mersey Railway in England, four of its 0-6-4T locomotives were sold to J & A Brown of New South ...

Terowie Railway Station
Terowie railway station was located on the Roseworthy–Peterborough line in the South Australian town of Terowie. History Terowie station opened in 1880 when the broad gauge line from Adelaide was completed. In 1881, it became a junction station when the narrow gauge line from Peterborough opened. This resulted in Terowie becoming an important transshipment point on the South Australian Railways network. The opening of the Trans-Australian Railway in 1917 further increased the amount of traffic, this ceased operating via Terowie in 1937 when the Adelaide to Redhill line was extended to Port Pirie. With the opening of the Leigh Creek Coalfield in the 1940s, the volume of freight transhipped increased again. This ceased with the opening of the Stirling North to Marree line on 27 July 1957. As part of the conversion of the Port Augusta to Broken Hill line to standard gauge, the line north of Terowie to Peterborough was converted to broad gauge on 12 January 1970, thus makin ...

Outer Harbor Railway Line
The Outer Harbor railway line is a suburban branch line in Adelaide, South Australia. It runs from Adelaide station through the north western suburbs to Port Adelaide and Outer Harbor. It is 21.9 kilometres in length, and shares part of its run with the Grange line. It is operated by Adelaide Metro. Since 2016, the line has been used as a shuttle for cruise liner passengers heading for Adelaide, with additional services provided. History Opening in 1856, the inaugural railway between Adelaide and Port Dock railway station was the second railway in the colony of South Australia, and the first government-owned railway in the British Empire. Port Adelaide junction was created when the railway was extended to cross the Port River to Le Fevre Peninsula. As industry developed on the west side of the Port River, and deeper harbour was required. Initially, this was at Semaphore, with the railway extended in 1882 as the now-closed Semaphore railway line to service the overseas ship ...

South Australian Railways K Class (narrow Gauge)
The South Australian Railways K class (narrow gauge) comprised a single locomotive. The design, by South Australian Railways Locomotive Engineer William Thow, was very similar to that of the broad-gauge K class, but it was smaller and lighter. It was allocated number 52 within the sequence allocated to the larger locomotives. The locomotive was built in 1883, five years after the first broad-gauge K class locomotive and a year before the last of the 18 such locomotives entered service. No. 52 was built by Dübs and Company of Glasgow, whereas Beyer, Peacock and Company, of Manchester, built all the broad-gauge class. The broad-gauge design was moderately "shrunk" to meet the smaller loading gauge of lines and the lower load-bearing capacity of track compared with the broad gauge. Some key specifications are compared in the table below. A major design weakness of the broad-gauge K class was the lack of a leading bogie (pilot truck), which led to frequent derailm ...

Pilot (locomotive)
A cowcatcher, also known as a pilot, is the device mounted at the front of a locomotive to deflect obstacles on the track that might otherwise damage or Derailment, derail it or the train. In the UK small metal bars called ''life-guards'', ''rail guards'' or ''guard irons'' are provided immediately in front of the wheels. They knock away smaller obstacles lying directly on the running surface of the railhead. Historically, fenced-off railway systems in Europe relied exclusively on those devices and cowcatchers were not required, but in modern systems cowcatchers have generally superseded them. Instead of a cowcatcher, trams use a device called a fender. Objects lying on the tram track come in contact with a sensor bracket, which triggers the lowering of a basket-shaped device to the ground, preventing the overrunning of the obstacles and dragging them along the road surface in front of the wheels. In snowy areas the cowcatcher also has the function of a Snowplow#Railway sno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driving Wheel
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. On diesel and electric locomotives, the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft drive and coupling rods were used in the past (e.g. in the Swiss Crocodile locomotive) but their use is now confined to shunting locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets which are linked together within the set. Diameter Driving wheels ...

Trailing Wheel
On a steam locomotive, a trailing wheel or trailing axle is generally an unpowered wheel or axle ( wheelset) located behind the driving wheels. The axle of the trailing wheels is usually located in a trailing truck. On some large locomotives, a booster engine was mounted on the trailing truck to provide extra tractive effort when starting a heavy train and at low speeds on gradients. Trailing wheels were used in some early locomotives but fell out of favor for a time during the latter 19th century. As demand for more powerful locomotives increased, trailing wheels began to be used to support the crew cab and rear firebox area. Trailing wheels first appeared on American locomotives between 1890 and 1895, but their axle worked in rigid pedestals. It enabled boilers to be lowered, since the top of the main frames was dropped down behind the driving wheels and under the firebox. The firebox could also be longer and wider, increasing the heating surface area and steam generation c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leading Wheel
The leading wheel or leading axle or pilot wheel of a steam locomotive is an unpowered wheel or axle located in front of the driving wheels. The axle or axles of the leading wheels are normally located on a leading truck. Leading wheels are used to help the locomotive negotiate curves and to support the front portion of the boiler. Overview Importantly, the leading bogie does not have simple rotational motion about a vertical pivot, as might first be thought. It must also be free to slip sideways to a small extent, otherwise the locomotive is unable to follow curves accurately, and some kind of springing mechanism is normally included to control that movement and provide a tendency to return to centre. A sliding bogie of that type was patented by William Adams in 1865. The first use of leading wheels is commonly attributed to John B. Jervis, who employed them in his 1832 design for a locomotive with four leading wheels and two driving wheels (a type that became known as the '' ...

List Of Railroad Truck Parts
A bogie or railroad truck holds the wheel sets of a rail vehicle. Axlebox An ''axle box'', also known as a ''journal box'' in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock. Plain bearings are now illegal for interchange service in North America. As early as 1908 axle boxes contained a set of long cylindrical rollers allowing the axle to rotate. It was also used on steam locomotives such as the Victorian Railways A2 class, the LMS Garratt, the LSWR 415 class, and the GCR Class 1. Center pin A large steel pin—or rod—which passes through the center plates on the body bolster and truck bolster. The truck turns about the pin, and stress is taken by the center plates.

Gunmetal
Gun metal, also known as red brass in the United States, is a type of bronze; an alloy of copper, tin and zinc. Proportions vary but 88% copper, 8–10% tin, and 2–4% zinc is an approximation. Originally used chiefly for making guns, it has largely been replaced by steel for that purpose. Gunmetal, which casts and machines well and is resistant to corrosion from steam and salt water, is used to make steam and hydraulic castings, valves, gears, statues and various small objects, such as buttons. It has a tensile strength of to , a specific gravity of 8.7, a Brinell hardness of 65 to 74, and a melting point of around 1,000 degrees Celsius The degree Celsius is the unit of temperature on the Celsius scale (originally known as the centigrade scale outside Sweden), one of two temperature scales used in the International System of Units (SI), the other being the Kelvin scale.
