Class 385
The British Rail Class 385 ''AT200'' is a type of electric multiple unit built by Hitachi Rail for Abellio ScotRail. A total of 70 units have been built, divided into 46 three-car and 24 four-car sets. Based on the design of the Hitachi A-train, they are part of the Hitachi AT200 product family. The trains were built to operate services on newly electrified lines in the Central Belt on a mixture of both suburban and inter-urban routes. Having been ordered by Abellio ScotRail during April 2015, the first trainsets entered service during late July 2018. Their introduction was somewhat delayed due to the need for infrastructure works to be completed, as well as minor technical issues with the trainsets being uncovered. By December 2019, all 70 of the Class 385 trainsets had been delivered. Hitachi has proposed developing a battery electric multiple unit (BEMU) variant of the Class 385, allowing such a trainset to traverse lines that aren't electrified at present. History In Oc ...

Abellio ScotRail, operating services under the name ScotRail, was the national train operating company of Scotland. A subsidiary of Abellio, it operated the ScotRail franchise from 1 April 2015, taking over from predecessor First ScotRail. The franchise ended on 31 March 2022 and was replaced by ScotRail, an operator of last resort owned by the Scottish Government. History In November 2013, Transport Scotland announced that Abellio, Arriva, FirstGroup, MTR Corporation and National Express had been shortlisted to bid for the new ScotRail franchise. In October 2014, the franchise was awarded to Abellio."Abellio awarded ScotRail franchise" '' [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Berwick Line
The North Berwick Branch is a short railway branch line built by the North British Railway to connect North Berwick, in East Lothian, Scotland to the East Coast Main Line (at Drem). It was built as a tactical means of excluding competitors from the area, and when it opened in 1850 it was loss making. The later development of North Berwick as a resort and a golfing centre transformed the branch line. Goods train operation on the branch ceased in 1968, but the line was electrified in 1991 and now enjoys a regular interval passenger service to Edinburgh. Authorisation and construction The North British Railway obtained its authorising Act of Parliament in the 1844 session, to build a line from Edinburgh to Berwick (later known as Berwick-upon-Tweed. From the outset this was to be a trunk railway, connecting at Berwick with the Newcastle and Berwick Railway and onwards to the growing English railway network. A Scottish network was forming too, and the competition between the promot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disc Brake
A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulically actuated disc brakes are the most commonly used form of brake for motor vehicles, but the principles of a disc brake are applicable to almost any rotating shaft. The components include the disc, master cylinder, and caliper (which contains a cylinder and two brake pads) on both sides of the disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated in a similar way to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. Other designs were not practical or widely available in cars for anot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electro-pneumatic Brake System On British Railway Trains
The electro-pneumatic brake system on British mainline railway trains was introduced in 1950 and remains the primary braking system for multiple units in service today, although London Transport underground trains had been fitted with EP brakes since the 1920s. The Southern Region of British Railways operated a self-contained fleet of electric multiple units for suburban and middle-distance passenger trains. From 1950, an expansion of the fleet was undertaken and the new build adopted a braking system that was novel in the UK, the electro-pneumatic brake in which compressed air brake operation was controlled electrically by the driver. This was a considerable and successful technical advance, enabling a quicker and more sensitive response to the driver's operation of brake controls. Origins From the 1920s, the Southern Railway of the UK and its predecessor companies had adopted electrification and multiple-unit train operation as a solution for dense and intensive passenger se ...

Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised an ...

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current colle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable-frequency Drive
A variable-frequency drive (VFD) is a type of motor drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and, depending on topology, to control associated voltage or current variation., quote is per definition on p. 4 of NEMA Standards Publication ICS 7.2-2021. VFDs may also be known as 'AFDs' (adjustable-frequency drives), 'ASDs' (adjustable-speed drives), 'VSDs' (variable-speed drives), 'AC drives', 'micro drives', 'inverter drives' or, simply, 'drives'. VFDs are used in applications ranging from small appliances to large compressors. An increasing number of end users are showing greater interest in electric drive systems due to more stringent emission standards and demand for increased reliability and better availability. Systems using VFDs can be more efficient than those using throttling control of fluid flow, such as in systems with pumps and damper control for fans. However, the global market pene ...

Insulated-gate Bipolar Transistor
An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch, which, as it was developed, came to combine high efficiency and fast switching. It consists of four alternating layers (P–N–P–N) that are controlled by a metal–oxide–semiconductor (MOS) gate structure. Although the structure of the IGBT is topologically the same as a thyristor with a "MOS" gate ( MOS-gate thyristor), the thyristor action is completely suppressed, and only the transistor action is permitted in the entire device operation range. It is used in switching power supplies in high-power applications: variable-frequency drives (VFDs), electric cars, trains, variable-speed refrigerators, lamp ballasts, arc-welding machines, induction hobs, and air conditioners. Since it is designed to turn on and off rapidly, the IGBT can synthesize complex waveforms with pulse-width modulation and low-pass filters, so it is also used in switchi ...

Edinburgh Waverley Railway Station
Edinburgh Waverley railway station (also known simply as Waverley; gd, Waverley Dhùn Èideann) is the principal railway station serving Edinburgh, Scotland. It is the second busiest station in Scotland, after Glasgow Central. It is the northern terminus of the East Coast Main Line, from , although some trains operated by London North Eastern Railway continue to other Scottish destinations beyond Edinburgh. Location Waverley station is situated in a steep, narrow valley between the medieval Old Town and the 18th century New Town. Princes Street, the premier shopping street, runs close to its north side. The valley is bridged by the North Bridge, rebuilt in 1897 as a three-span iron and steel bridge, on huge sandstone piers. This passes high above the station's central section, with the greater half of the station being west of North Bridge. The central booking hall is just west of the northern massive stone pier of the bridge and cleverly hides it within its bulk. Wa ...
