Rail Transport In New Zealand
Rail transport in New Zealand is an integral part of Transport in New Zealand, New Zealand's transport network, with a nationwide network of of track linking most major cities in the North and South Islands, connected by inter-island rail and road ferries. Rail transport in New Zealand has a particular focus on bulk freight exports and imports, with 19 million net tonnes moved by rail annually, accounting for more than half of rail revenue. Rail transport played an important role in the opening up and development of the hinterland outside of New Zealand's predominantly dispersed and coastal settlements. Starting with the Ferrymead Railway in 1863, most public railway lines were short, built by Provinces of New Zealand, provincial governments and connected major centres to their nearest seaport (such as Christchurch and its port at Lyttelton Harbour). From the 1870s, the focus shifted to building a nationwide network linking major centres, especially during the The Vogel Era, ...

Waikanae
Waikanae (, ) is a town on the Kāpiti Coast, north of the Wellington, New Zealand. The name is a Māori language, Māori word meaning "waters" (''wai'') "of the flathead grey mullet, grey mullet". The area surrounding the town is notable for its beach, the Waikanae River estuary, the Kapiti Marine Reserve, and Kapiti Island, which lies offshore in the Tasman Sea. The town is considered one of the top retirement destinations in the Wellington Region, because of it having year-round mild temperatures, moderate rainfall, and less wind than Wellington. The town is northeast of Paraparaumu, and southwest of Ōtaki, New Zealand, Ōtaki. The Waikanae railway station is the northernmost station in the Public transport in the Wellington Region, Metlink passenger rail network, linking with Wellington railway station in Central Wellington. Geography Waikanae lies in a setting of open farmland and forest between the Tasman Sea and the rugged Tararua Range. Prior to human settlemen ...

Passing Loop
A passing loop (UK usage) or passing siding (North America) (also called a crossing loop, crossing place, refuge loop or, colloquially, a hole) is a place on a single line railway or tramway, often located at or near a station, where trains or trams travelling in opposite directions can pass each other. Trains/trams going in the same direction can also overtake, provided that the signalling arrangement allows it. A passing loop is double-ended and connected to the main track at both ends, though a dead end siding known as a refuge siding, which is much less convenient, can be used. A similar arrangement is used on the gauntlet track of cable railways and funiculars, and in passing places on single-track roads. Ideally, the loop should be longer than all trains needing to cross at that point. Unless the loop is of sufficient length to be dynamic, the first train to arrive must stop or move very slowly, while the second to arrive may pass at speed. If one train is too lo ...

Single Track (rail)
A single-track railway is a railway where trains traveling in both directions share the same track. Single track is usually found on lesser-used rail lines, often branch lines, where the level of traffic is not high enough to justify the cost of constructing and maintaining a second track. Advantages and disadvantages Single track is significantly cheaper to build and maintain, but has operational and safety disadvantages. For example, a single-track line that takes 15 minutes to travel through would have capacity for only two trains per hour in each direction safely. By contrast, a double track with signal boxes four minutes apart can allow up to 15 trains per hour in each direction safely, provided all the trains travel at the same speed. This hindrance on the capacity of a single track may be partly overcome by making the track one-way on alternate days. Long freight trains are a problem if the passing stretches are not long enough. Other disadvantages include the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

25 KV AC Railway Electrification
Railway electrification systems using alternating current (AC) at are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60Hz), which simplifies traction substations. The development of 25kV AC electrification is closely connected with that of successfully using utility frequency. This electrification is ideal for railways that cover long distances or carry heavy traffic. After some experimentation before World War II in Hungary and in the Black Forest in Germany, it came into widespread use in the 1950s. One of the reasons it was not introduced earlier was the lack of suitable small and lightweight control and rectification equipment before the development of solid-state rectifiers and related technology. Another reason was the increased clearance required under bridges and in tunnels, which would have required major civil engineering in order to provide the increased clearance to live parts.

Kapiti Line
Metlink's Kapiti Line is the Railway electrification system, electrified southern portion of the North Island Main Trunk railway between New Zealand's capital city, Wellington, and Waikanae on the Kāpiti Coast, operated by Transdev Wellington on behalf of Greater Wellington Regional Council. Trains run frequently every day, with stops at 16 stations. Until 20 February 2011 it was known as the Paraparaumu Line. Construction The Kapiti Line was constructed by the Wellington and Manawatu Railway Company (W&MR) as part of its line between Wellington and Longburn, south of Palmerston North. It was built by a group of Wellington businessmen frustrated with the indecision of the government about the construction of a west coast route out of Wellington. Construction of the line began in September 1882 and followed a circuitous, steep route via Johnsonville, New Zealand, Johnsonville. It was opened to Plimmerton in October 1885 and completed on 3 November 1886. The final spike was dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, Electric multiple unit, electric multiple units, trolleybuses or trams. The generic term used by the International Union of Railways for the technology is ''overhead line''. It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire. An overhead line consists of one or more wires (or Overhead conductor rail, rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a High voltage, high-voltage Electricity distribution, electrical grid. Overview Electric trains that collect their current from overhead lines use a de ...

Direct Current
Direct current (DC) is one-directional electric current, flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor (material), conductor such as a wire, but can also flow through semiconductors, electrical insulation, insulators, or even through a vacuum as in electron beam, electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A archaism, 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 ''Electric current, current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains Electronics, electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
