Lioness Line
The Watford DC line is a suburban line from London Euston to Watford Junction in Watford, Hertfordshire. Its services are operated by London Overground. The line runs beside the West Coast Main Line (WCML) for most of its length. The London Underground Bakerloo line shares the section of the line from Queen's Park to Harrow & Wealdstone. The rolling stock used on the line are Class 710 "Aventras" made by Bombardier. The "DC" in the title refers to line being electrified using direct current. This was done in the early twentieth century with conductor rails (for compatibility with the London Underground's four-rail system and the now AC/DC-split semi-orbital North London Line). By contrast, the WCML uses overhead alternating current. History Services on this line began when London and North Western Railway (LNWR) completed the Camden to Watford Junction ''new line'' in 1912, to provide additional suburban capacity and more outer-suburban services running non-stop ...

Commuter Rail
Commuter rail, or suburban rail, is a passenger rail transport service that primarily operates within a metropolitan area, connecting commuters to a central city from adjacent suburbs or commuter towns. Generally commuter rail systems are considered heavy rail, using electrified or diesel trains. Distance charges or zone pricing may be used. The term can refer to systems with a wide variety of different features and service frequencies, but is often used in contrast to rapid transit or light rail. Similar non-English terms include ''Treno suburbano'' in Italian, ''Cercanías'' in Spanish, Aldiriak in Basque, Rodalia in Catalan/Valencian, Proximidades in Galician, ''Proastiakos'' in Greek, ''Train de banlieue'' in French, '' Banliyö treni '' in Turkish, ''Příměstský vlak'' or ''Esko'' in Czech, ''Elektrichka'' in Russian, ''Pociąg podmiejski '' in Polish and ''Pendeltåg'' in Swedish. Some services share similarities with both commuter rail and high-frequency rapid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

London And North Western Railway
The London and North Western Railway (LNWR, L&NWR) was a British railway company between 1846 and 1922. In the late 19th century, the L&NWR was the largest joint stock company in the United Kingdom. In 1923, it became a constituent of the London, Midland and Scottish (LMS) railway, and, in 1948, the London Midland Region of British Railways: the LNWR is effectively an ancestor of today's West Coast Main Line. History The company was formed on 16 July 1846 by the amalgamation of the Grand Junction Railway, London and Birmingham Railway and the Manchester and Birmingham Railway. This move was prompted, in part, by the Great Western Railway's plans for a railway north from Oxford to Birmingham. The company initially had a network of approximately , connecting London with Birmingham, Crewe, Chester, Liverpool and Manchester. The headquarters were at Euston railway station. As traffic increased, it was greatly expanded with the opening in 1849 of the Great Hall, designed by P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

North London Line
The North London line (NLL) is a railway line which passes through the inner suburbs of west, north-west, north, and east London, England between Richmond in the south-west and Stratford in the east, avoiding central London. Its route is a rough semicircle. Although much of it originated as part of the North London Railway, the current route is the result of a series of amalgamations, closures and reopenings, and has a mix of third-rail and overhead electrical power supply. It remains heavily used by freight services in addition to the main London Overground (LO) service. Between Richmond and Gunnersbury, London Underground's District line shares tracks with London Overground services; the entire route is owned and maintained by Network Rail. TfL took over the line in 2007 and introduced new stock as well as putting the line on the Tube map. It closed for four months in 2010 between and and had a reduced service for another year to allow platform extensions and signalling u ...

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 ...

Third Rail
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third rail systems are usually supplied from direct current electricity. Modern tram systems, street-running, avoid the risk of electrocution by the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge railways. Description Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") fo ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Harrow & Wealdstone Station
Harrow & Wealdstone is a London Underground and railway station on the Watford DC line and West Coast Main Line in Harrow and Wealdstone in the London Borough of Harrow. It is on the line from London Euston station. It is also the northern terminus of the Bakerloo line and the next station towards south is Kenton. It is served by London Underground (Bakerloo line), London Overground, London Northwestern Railway, and Southern services. The station is located between The Bridge (which joins the southern end of High Street) and Sandridge Close, with entrances leading to both. It is one of the oldest stations in the London region in existence. The Harrow and Wealdstone rail crash of 1952, which killed 112 people, occurred at the station. It remains Britain's worst peacetime rail disaster. History The station was opened by the London and Birmingham Railway (L&BR) as Harrow on 20 July 1837 in what was then rural Middlesex. At the time the station was built, the area was fields an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen's Park (London) Station
Queen's Park is an interchange station on the Watford DC line and Bakerloo line served by London Overground and London Underground respectively. It lies at the southern end of Salusbury Road, near the south-east corner of the public park from which the area now known as Queens Park has taken its modern name. The station is in Travelcard Zone 2. History The station was first opened by the London and North Western Railway (LNWR) on 2 June 1879, on the main line from London to Birmingham. Services on the Bakerloo line were extended from Kilburn Park to Queen's Park on 11 February 1915. On 10 May 1915, Bakerloo services began to operate north of Queen's Park as far as Willesden Junction over the recently built Watford DC line tracks shared with the LNWR. London Midland previously made three operational calls daily, which were not found in public timetables. As of the December 2013 timetable these stops no longer exist, with no main line services calling at the station.GB Nation ...

West Coast Main Line
The West Coast Main Line (WCML) is one of the most important railway corridors in the United Kingdom, connecting the major cities of London and Glasgow with branches to Birmingham, Liverpool, Manchester and Edinburgh. It is one of the busiest mixed-traffic railway routes in Europe, carrying a mixture of intercity rail, regional rail, commuter rail and rail freight traffic. The core route of the WCML runs from London to Glasgow for and was opened from 1837 to 1869. With additional lines deviating to Northampton, Birmingham, Manchester, Liverpool and Edinburgh, this totals a route mileage of . The Glasgow–Edinburgh via Carstairs line connects the WCML to Edinburgh, however the main London–Edinburgh route is the East Coast Main Line. Several sections of the WCML form part of the suburban railway systems in London, Coventry, Birmingham, Liverpool, Manchester and Glasgow, with many more smaller commuter stations, as well as providing links to more rural towns. It is one of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watford
Watford () is a town and borough in Hertfordshire, England, 15 miles northwest of Central London, on the River Colne. Initially a small market town, the Grand Junction Canal encouraged the construction of paper-making mills, print works, and breweries. While industry has declined in Watford, its location near London and transport links has attracted several companies to site their headquarters in the town. Cassiobury Park is a public park that was once the manor estate of the Earls of Essex. The town developed next to the River Colne on land belonging to St Albans Abbey. In the 12th century, a charter was granted allowing a market, and the building of St Mary's Church began. The town grew partly due to travellers going to Berkhamsted Castle and the royal palace at Kings Langley. A mansion was built at Cassiobury in the 16th century. This was partly rebuilt in the 17th century and another country house was built at The Grove. The Grand Junction Canal in 1798 and th ...
