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 can be supplied 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 continuous infrastructure like electric third rail or overhead catenary. On the down side is the weight of the batteries, which raises the vehicle weight, affecting the range before recharging of between . Currently, battery electric units have a higher purchase price and running costs 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, broad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Little River Branch
The Little River Branch was a branch line railway that formed part of New Zealand's national rail network. It diverged from the Southbridge Branch in Lincoln and ran down to Banks Peninsula in the Canterbury region of the South Island. It was opened to Little River on 11 March 1886 and operated until 1 July 1962. Construction Little River contained one of only two significant stands of timber in the Canterbury region (the other, near Oxford, was serviced by the Oxford Branch), and accordingly, plans were made to build a line to provide convenient transportation and stimulate economic activity. These were finalised in 1879, and construction was under way by the next year. On 16 May 1882, the first 27.44 km of the line were opened to Birdling's Flat, and almost four years later, the next nine kilometres were opened to Little River. There were proposals to extend the line as far as Akaroa, but these did not eventuate and Little River remained the terminus. Ope ...

Railway Electrification System
Railway electrification is the use of electric power for the propulsion of rail transport. 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 and contacted by a pantograph, or a third rail mounted at track level and contacted by a sliding " pickup ...

DB Class ETA 150
The accumulator cars of Class ETA 150 (Class 515 from 1968) were German railcars used extensively by Deutsche Bundesbahn (DB) for 40 years. They ran on both main and branch lines. By comparison with the Uerdingen railbus, the railcars were quieter (despite the typical whine of their DC motors), rode more smoothly on the rails owing to the weight of the batteries, and were pollution-free (no smoke or fumes). They were very popular with passengers, who nicknamed them ''Akkublitz'' (''Battery Lightning''), ''Säurebomber'' (''Acid Bombers''), ''Steckdosen-InterCity'' (''Socket InterCitys''), ''Taschenlampen-Express'' (''Pocket Torch Express''), or ''Biene Maja'' (''Maya the Bee'' – because of the sound they made when at speed). 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 become Deutsche Reichsbahn's Class ET ...

Scotland
Scotland is a Countries of the United Kingdom, country that is part of the United Kingdom. It contains nearly one-third of the United Kingdom's land area, consisting of the northern part of the island of Great Britain and more than 790 adjacent Islands of Scotland, islands, principally in the archipelagos of the Hebrides and the Northern Isles. To the south-east, Scotland has its Anglo-Scottish border, only land border, which is long and shared with England; the country is surrounded by the Atlantic Ocean to the north and west, the North Sea to the north-east and east, and the Irish Sea to the south. The population in 2022 was 5,439,842. Edinburgh is the capital and Glasgow is the most populous of the cities of Scotland. The Kingdom of Scotland emerged as an independent sovereign state in the 9th century. In 1603, James VI succeeded to the thrones of Kingdom of England, England and Kingdom of Ireland, Ireland, forming a personal union of the Union of the Crowns, three kingdo ...

Ballater
Ballater (, ) 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.

British Rail BEMU
The British Rail BEMU was an experimental two-car battery electric multiple unit (BEMU), converted from the prototype Derby Lightweight Diesel multiple units. The train was powered by many lead-acid batteries, and was used on the Deeside Railway from Aberdeen to Ballater in Scotland from April 1958 until it was finally withdrawn in December 1966. The North of Scotland Hydro-Electric Board initiated the design and was a joint sponsor. The board promised to supply power at three farthings per unit for a fixed two-year period. It provided an 11kV supply to a charger at Aberdeen's platform 1 and a 6.6kV supply to a charger at Ballater. Career The estimated cost of the fit-out was £50,000, with the two coaches accounting for almost half of that. Because each set of batteries weighed about eight tons, the underframe of the carriages needed strengthening, at a budgeted cost of £2,000. Motors, conduits and cabling were costed at £5,000. Power was provided from two Siemens-Schucke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Railways
British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most rail transport in Great Britain from 1948 to 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in January 1963, when it was formally renamed the British Railways Board. British Railways was formed on 1 January 1948 as a result of the Transport Act 1947, which nationalisation, nationalised the Big Four (British railway companies), Big Four British railway companies along with some other (but not all) smaller railways. Profitability of the railways became a pressing concern during the 1950s, leading to multiple efforts to bolster performance, including some line closures. The History of rail transport in Great Britain 1948–1994#The Modernisation Plan, 1955 Modernisation Plan formally directed a process of dieselisation and Railway electrification in Great Britain, electrification ...
