Acela Express (trainset)
The first-generation Acela Express trainset is a unique set of vehicles used on the ''Acela'', Amtrak's flagship High-speed rail#Americas, high-speed service along the Northeast Corridor (NEC) in the Northeastern United States. When they debuted in 2000, the sets were the fastest in the Americas; reaching on of the route. They were built between 1998 and 2001 by a consortium of Alstom and Bombardier Transportation, Bombardier. Each set has two power cars derived from units that Alstom built for the Train a grande vitesse, TGV, and six passenger cars derived from the LRC (train), LRC that Bombardier built for Via Rail. While the Acela sets were based on TGV equipment, the power cars and passenger cars are much heavier in order to meet the Federal Railroad Administration's crash standards. The extra weight leads to the Acela's power-to-weight ratio being about per tonne, compared to for a SNCF TGV Réseau trainset. Unlike the TGV, the Acela sets employ Tilting train, active til ...

Pantograph (transport)
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 and patented b ...

LRC (train)
The LRC (a bilingual acronym: in English: ''Light, Rapid, Comfortable''; in french: Léger, Rapide, et ) is a series of lightweight diesel-powered passenger trains that were used on short- to medium-distance inter-city service in the Canadian Provinces of Ontario and Quebec. LRC was designed to run with locomotives, or power cars, at both ends and provide service on non-upgraded railway routes. To accomplish this, the LRC Passenger car (rail), passenger cars feature tilting train, active-tilt technology to reduce the forces on the passengers when a train travels at high speeds through curves. LRCs have reached speeds as high as on test runs. On its only regular service route, on the Québec City–Windsor Corridor (Via Rail), Quebec City–Windsor Corridor, wear concerns, signalling issues and conflicts with slower-moving freight trains limit this to or less. For service at these speeds, a single power car was used. Special signage allowed the LRC to run at higher speeds than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train A Grande Vitesse
The TGV (french: Train à Grande Vitesse, "high-speed train"; previously french: TurboTrain à Grande Vitesse, label=none) is France's intercity high-speed rail service, operated by SNCF. SNCF worked on a high-speed rail network from 1966 to 1974 and presented the project to President Georges Pompidou who approved it. Originally designed as turbotrains to be powered by gas turbines, TGV prototypes evolved into electric trains with the 1973 oil crisis. In 1976 the SNCF ordered 87 high-speed trains from Alstom. Following the inaugural service between Paris and Lyon in 1981 on the LGV Sud-Est (LGV for ''Ligne à Grande Vitesse''; "high-speed line"), the network, centered on Paris, has expanded to connect major cities across France (including Marseille, Lille, Bordeaux, Strasbourg, Rennes and Montpellier) and in neighbouring countries on a combination of high-speed and conventional lines. The TGV network in France carries about 110 million passengers a year. The high-speed tracks, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Car
In rail transport, the expression power car may refer to either of two distinct types of rail vehicle: *a vehicle that propels, and commonly also controls, a passenger train, multiple unit or tram, often as the lead vehicle; *a vehicle equipped with machinery for supplying heat or electrical power to other parts of a train. The first of these types of vehicle is closely related to the locomotive. What differentiates the locomotive and the first type of power car is their construction or use. A locomotive can be physically separated from its train and does nothing but provide propulsion and control (and heat or electricity for passenger trains). On the other hand, a power car of the first type is frequently an integral part of its train, and if the train uses distributed traction, some of the car's interior space may be used for carrying passengers or cargo. Examples United States Nearly all high speed trains use power cars, frequently at both ends. An example of these are the A ...

Americas
The Americas, which are sometimes collectively called America, are a landmass comprising the totality of North and South America. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon, St. Lawrence River–Great Lakes basin, Mississippi, and La Plata. Since the Americas extend from north to south, the climate and ecology vary widely, from the arctic tundra of Northern Canada, Greenland, and Alaska, to the tropical rain forests in Central America and South America. Humans first settled the Americas from Asia between 42,000 and 17,000 years ago. A second migration of Na-Dene speakers followed later ...

Northeastern United States
The Northeastern United States, also referred to as the Northeast, the East Coast, or the American Northeast, is a geographic region of the United States. It is located on the Atlantic coast of North America, with Canada to its north, the Southern United States to its south, and the Midwestern United States to its west. The Northeast is one of the four regions defined by the U.S. Census Bureau for the collection and analysis of statistics. The region is usually defined as including nine U.S. states: Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont. The U.S. Census Bureau–defined region of the Northeastern United States has a total area of with of that being land mass, making it the smallest region of the United States by both land mass and total area. The Northeastern region is the nation's most economically developed, densely populated, and culturally diverse region. Of the nation's four census regions, the No ...

High-speed Rail
High-speed rail (HSR) is a type of rail system that runs significantly faster than traditional rail, using an integrated system of specialised rolling stock and dedicated tracks. While there is no single standard that applies worldwide, lines built to handle speeds above or upgraded lines in excess of are widely considered to be high-speed. The first high-speed rail system, the Tōkaidō Shinkansen, began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains mostly operate on standard gauge tracks of continuously welded rail on grade-separated rights of way with large radii. However, certain regions with wider legacy railways, including Russia and Uzbekistan, have sought to develop a high speed railway network in Russian gauge. There are no narrow gauge high-speed trains; the fastest is the Cape gauge Spirit of Queensland at . Many countries have developed, or are currently building, high-speed rail infrastructure to connect major citie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acela
The ''Acela'' ( ; originally the ''Acela Express'' until September 2019) is Amtrak's flagship service along the Northeast Corridor (NEC) in the Northeastern United States between Washington, D.C. and Boston via 13 intermediate stops, including Baltimore, New York City and Philadelphia. ''Acela'' trains are the fastest in the Americas, reaching (qualifying as high-speed rail), but only over of the route. ''Acela'' carried more than 3.4 million passengers in fiscal year 2016; second only to the slower and less expensive ''Northeast Regional'', which had over 8 million passengers. Its 2016 revenue of $585 million was 25% of Amtrak's total. ''Acela'' operates along routes that are used by freight and slower regional passenger traffic, and reaches the maximum allowed speed of the tracks only along some sections, with the fastest peak speed along segments between Mansfield, Massachusetts and Richmond, Rhode Island, and New Brunswick and South Brunswick (Trenton in 2024), New Je ...

Advanced Civil Speed Enforcement System
Advanced Civil Speed Enforcement System (ACSES) is a positive train control cab signaling system developed by Alstom. The system is designed to prevent train-to-train collisions, protect against overspeed, and protect work crews with temporary speed restrictions. The information about permanent and temporary speed restrictions is transmitted to the train by transponders (Balises) lying in the track, coded track circuits and digital radio. It was installed beginning in 2000 on all of Amtrak's Northeast Corridor (except MTA territory) between Washington and Boston, and has been fully active since December 2015, a few months after the 2015 Philadelphia train derailment which it would have prevented. General system design ACSES provides railway trains with positive enforcement of "civil" speed restrictions (those based on the physical characteristics of the line). The on-board components keep track of a train's position and continuously calculates a maximum safe braking curve for u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brake Shoe
A brake shoe is the part of a braking system which carries the brake lining in the drum brakes used on automobiles, or the brake block in train brakes and bicycle brakes. A device that is put on a track to slow down railroad cars is also called brake shoe. Automobile drum brake The brake shoe carries the brake lining, which is riveted or glued to the shoe. When the brake is applied, the shoe moves and presses the lining against the inside of the drum. The friction between lining and drum provides the braking effort. Energy is dissipated as heat. Modern cars have disc brakes all round, or discs at the front and drums at the rear. An advantage of discs is that they can dissipate heat more quickly than drums so there is less risk of overheating. The reason for retaining drums at the rear is that a drum is more effective than a disc as a parking brake. Railway tread brake The brake shoe carries the brake block. The block was originally made of wood, then usage of cast iron ... [...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 another 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
