Victorian Railways E Class (electric)
The Victorian Railways E class was a class of electric locomotive that ran on the Victorian Railways from 1923 until 1984. Introduced shortly after the electrification of the suburban rail system in Melbourne, Australia, and based on the same electrical and traction equipment as Melbourne's early suburban electric multiple unit fleet, they provided power for suburban goods services and shunting for six decades. History With the rapid expansion of Melbourne's suburban electrification scheme, becoming by 1924 the largest in the world at 346 miles (557 km), the Victorian Railways decided to utilise the advantages of electric traction for suburban goods services, which until then had been hauled by steam locomotives such as the Y class 0-6-0, E class 2-4-2T and later Dde class 4-6-2T. In 1923 it introduced two electric locomotives of 620 hp (460 kW), built at VR's Newport and Jolimont Workshops with the same General Electric traction motors and related electrical ...

Electric
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

Victorian Railways Y Class
The Victorian Railways Y class was a class of 0-6-0 steam locomotives. The Y class was an example of the new policy of standard design principles being adopted by the railways of the time. The original pattern locomotive (an 0-6-0 tender engine) was built by Kitson & Co. at Leeds in England in 1885, and was exhibited, along with E426, in 1888 at the Melbourne Centennial Exhibition, held in the Melbourne Exhibition Building. The other 30 locomotives of this type were built by the Phoenix Foundry at Ballarat in 1888-1889. They were given road numbers 383 to 441 (odd numbers only), and the pattern engine 445, 443 having been allotted to an "Old" R class. They were big locomotives for their time—in fact the largest and most powerful 0-6-0s to run in Australia. The class excelled in their performance and acceptance by crews. They were often seen on suburban passenger trains prior to electrification, finishing their lives as yard shunters. Withdrawal of the Y class began in 1926 ...

Victorian Railways C Class
The C class was a mainline goods locomotive of the 2-8-0 'Consolidation' type that ran on the Victorian Railways between 1918 and 1962. Although its original design had some key shortcomings, a number of improvements were made over the class' long career on the VR, many of which were subsequently applied to other locomotive classes on the system. History Designed by Chief Mechanical Engineer W. M. Shannon, the C class was the first goods locomotive designed and built entirely in-house by the Victorian Railways Newport Workshops, following on from the successful Dd and A2 class passenger locomotives. When class leader C 1 was introduced in 1918, it was the heaviest and most powerful steam locomotive in Australia. It had been necessary for Victorian Railways to strengthen bridges at Dudley Street, North Melbourne and along the lines to Woodend and Seymour on which the new locomotive was expected to run. Production The prototype locomotive C 1 was the only one of the cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 one ...

Multiple-unit Train Control
Multiple-unit train control, sometimes abbreviated to multiple-unit or MU, is a method of simultaneously controlling all the traction equipment in a train from a single location—whether it is a multiple unit comprising a number of self-powered passenger cars or a set of locomotives—with only a control signal transmitted to each unit. This contrasts with arrangements where electric motors in different units are connected directly to the power supply switched by a single control mechanism, thus requiring the full traction power to be transmitted through the train. A set of vehicles under multiple unit control is referred to as a consist in the United States. Origins Multiple unit train control was first used in electric multiple units in the 1890s. The Liverpool Overhead Railway The Liverpool Overhead Railway opened in 1893 with two-car electric multiple units, controllers in cabs at both ends directly controlling the traction current to motors on both cars.

Victorian Railways L Class
The Victorian Railways L class was a class of electric locomotives built by English Electric and operated by the Victorian Railways and later V/Line from 1953 until 1987 primarily on the Gippsland line. They were the only class of main line electric locomotive operated in Victoria. History Australia was a relatively early adopter of electric traction and Electric Multiple Unit trains, with a General Electric advertisement in ''Railway Age'' magazine of 1924 claiming that Melbourne had the largest suburban electrification scheme in the world at 346 miles (557 km). However, electrification in Victoria had until the 1950s been restricted to the Melbourne suburban network. Apart from the EMU fleet the only electric locomotives operated by the Victorian Railways (VR) were a fleet of 12 small 620 hp (460 kW) types (two steeple cabs 1100 and 1101 plus ten box cabs 1102 to 1111). In the 1960s the latter became classified E class. They were all built in the 1920s at VR's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Chair
An electric chair is a device used to execute an individual by electrocution. When used, the condemned person is strapped to a specially built wooden chair and electrocuted through electrodes fastened on the head and leg. This execution method, conceived in 1881 by a Buffalo, New York dentist named Alfred P. Southwick, was developed throughout the 1880s as a supposed humane alternative to hanging, and first used in 1890. The electric chair has been used in the United States and, for several decades, in the Philippines. While death was originally theorized to result from damage to the brain, it was shown in 1899 that it primarily results from ventricular fibrillation and eventual cardiac arrest. Although the electric chair has long been a symbol of the death penalty in the United States, its use is in decline due to the rise of lethal injection, which is widely believed to be a more humane method of execution. While some states still maintain electrocution as a legal method of ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swing Door (train)
Swing Door trains, commonly known as "Dogboxes" or "Doggies", were wooden-bodied electric multiple unit (EMU) trains that operated on the suburban railway network of Melbourne, Victoria, Australia. Swing Door cars had outward-opening doors. They were reasonably narrow, to ensure that two passing trains could not foul each other if doors were accidentally left open. At certain locations clearances were tight and there are stories of Swing Door cars losing doors that were not closed. The fleet could be seen running in any arrangement, from one car (using a double-ended M car), up to seven cars. History The Swing Door trains were originally and steam-hauled bogie passenger cars, the majority of which had been built between 1887 and 1893. When converted to electric traction between 1917 and 1924, the cars were extended by two compartments to a total length of , and then fitted onto new under-frames and bogies.S.E. Dornan and R.G.

Tait (train)
The Tait trains were a wooden bodied Electric Multiple Unit train that operated on the suburban railway network of Melbourne, Victoria, Australia. They were introduced in 1910 by the Victorian Railways as steam locomotive hauled cars, and converted to electric traction from 1919 when the Melbourne electrification project was underway. The trains derived their name from Sir Thomas James Tait, the chairman of commissioners of the Victorian Railways from 1903 to 1910. The first cars were built during 1909 with the last entering service in 1952. Tait trains were initially referred to as "Sliding Door" trains, as opposed to the Swing Door trains then in service. From the 1950s, they became known as Reds or Red Rattlers, following the introduction of the blue-painted Harris trains. Layout Tait trains had a partly open saloon layout, with bench seats running across the train, the saloon being divided by partitions into a number of smaller areas. Each seating aisle was provided wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-6-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The locomotive became almost globally known as a Pacific type. Overview The introduction of the design in 1901 has been described as "a veritable milestone in locomotive progress". On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric locomotive, electric or diesel locomotive, diesel-electric locomotives during the 1950s and 1960s. Nevertheless, new Pacific designs continued to be built until the mid-1950s. The type is generally considered to be an enlargement of the 4-4-2 (locomotive), Atlantic type, although its NZR Q class (1901), prototype had ...
