Battery Electric Multiple Unit
A battery electric multiple unit (BEMU), battery electric railcar or accumulator railcar is an electrically driven multiple unit or railcar whose energy is derived from rechargeable batteries driving the traction motors. Prime advantages of these vehicles is that they do not use fossil fuels such as coal or diesel fuel, emit no exhaust gases and do not require the railway to have expensive infrastructure like electric ground rails or overhead catenary. On the down side is the weight of the batteries, which raises the vehicle weight, and their range before recharging of between . Currently, battery electric units have a higher purchase price and running cost than petrol or diesel railcars. One or more charging stations are required along the routes they operate, unless operation is on a mixture of electrified and unelectrified track, with the batteries being charged from the electrified track. Battery technology has greatly improved over the past 20 years broadening the scope of u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acumulador De Carga Rápida
Acumulador de Carga Rápida (ACR) () is a battery electric tram system marketed by Construcciones y Auxiliar de Ferrocarriles (CAF) of Spain. Trams equipped with ACR are fast-charged while at stops; elsewhere they require no overhead line, which is desirable for reasons of safety, reliability, cost, and aesthetics. It also allows regenerative braking where direct current electrification systems cannot return (much) energy to the grid. Operation ACR-equipped trams are powered between stops by discharging a rooftop supercapacitor battery, weighing around , which gives a range of around . The battery is partially recharged between stops by regenerative braking; at stops, it is completely recharged in around thirty seconds by current drawn via pantograph from a short section of overhead line. Marketing CAF offers ACR as an option on its Urbos 3 tram; for retrofitting on trams built by CAF or other manufacturers; and for standard gauge and metre gauge tram systems. ACR’s most ...

Urbos 3
The CAF Urbos is a family of trams, streetcars, and light rail vehicles built by CAF. The Basque manufacturer CAF previously manufactured locomotives, passenger cars, regional, and underground trains. In 1993, CAF started building trams for Metrovalencia, with the delivery of 16 trams until 1999. This was a variant of a Siemens design and some components were delivered by Siemens, including bogies and traction motors. This design was also sold to Lisbon Trams in 1995; CAF then decided to design and build the Urbos in-house. There are three generations of the CAF Urbos, namely the Urbos 1, Urbos 2, and Urbos 3. The first generation was ordered by the Bilbao tram operator, who received eight trams between 2002 and 2004. The second generation was sold to other operators in Spain, and the third generation is sold in Spain, elsewhere in Europe, the United States, Australia and in the UK. Manufacturing locations include Beasain, Zaragoza and Linares, Spain; Elmira, New York, USA; Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Electrification System
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units (passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by a s ...

DB Class ETA 150
The accumulator cars of Class ETA 150 (Class 515 from 1968) were German railbuses used extensively by Deutsche Bundesbahn (DB) for 40 years. The railcars were very comfortable to travel in because they were quiet (despite the typical Dc_motors#Noise, whine of their DC motors), rode well on the rails owing to the weight of the batteries, and were pollution-free (no smoke or fumes). They ran on both main and branch lines. They were very popular with passengers, who nicknamed them ''Akkublitz'' (''Battery Lightning''), ''Säurebomber'' (''Acid Bombers''), ''Steckdosen-Intercity (Deutsche Bahn), InterCity'' (''Socket InterCitys''), ''Taschenlampen-Express'' (''Pocket Torch Express''), or ''Biene Maja'' (''Maya the Bee'' – because of the sound they made when under way). History As a result of many years of favourable experience with this type of vehicle (the Prussian state railways had placed accumulator railcars in service as early as 1907 – these would later becom ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Ballater
Ballater (, gd, Bealadair) is a village in Aberdeenshire, Scotland, on the River Dee, immediately east of the Cairngorm Mountains. Situated at an elevation of , Ballater is a centre for hikers and known for its spring water, once said to cure scrofula. It is home to more than 1400 inhabitants and has had a long connection with the British Royal Family. History The medieval pattern of development along this reach of the River Dee was influenced by the ancient trackways across the Grampian Mounth, which determined strategic locations of castles and other Deeside settlements of the Middle Ages. In the early 14th century, the area was part of the estates of the Knights of St John, but the settlement did not develop until around 1770; first as a spa resort to accommodate visitors to the Pannanich Mineral Well, then later upon the arrival of the railway in 1866 it was visited by many tourists taking advantage of the easier access thus afforded.
