JetTrain
The JetTrain was an experimental high-speed passenger train concept created by Bombardier Transportation in an attempt to make European-style high-speed service more financially appealing to passenger railways throughout North America. It was designed to use the same LRC-derived tilting carriages as the Acela Express trains that Bombardier built for Amtrak in the 1990s, which used all-electric locomotives. Unlike the Acela, powered electrically by overhead lines, the JetTrain would have used a combination of a gas-turbine engine, a low-power diesel engine, a reduction gearbox, and two alternators to power electric traction motors. This would have allowed it to run at high speeds on non-electrified lines. Description Gas turbine engines Turbine engines use as much as 65% of their overall generated power to run the compressor at the front of the engine. This means that when the engine is set to idle, with no net energy output, the engine is still burning 65% of the fuel it ...

Acela Express
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 ...

Turboliner
The Turboliners were a family of gas turbine trainsets built for Amtrak in the 1970s. They were among the first new equipment purchased by Amtrak to update its fleet with faster, more modern trains. The first batch, known as RTG, were built by the French firm ANF and entered service on multiple routes in the Midwestern United States in 1973. The new trains led to ridership increases wherever used, but the fixed consist proved a detriment as demand outstripped supply. The high cost of operating the trains led to their withdrawal from the Midwest in 1981. The second batch, known as RTL, were of a similar design but manufactured by Rohr Industries. These entered service on the Empire Corridor in the state of New York in 1976. The RTLs remained in service there through the 1990s, supplemented by several rebuilt RTGs. In the late 1990s and early 2000s, New York and Amtrak partnered to rebuild the RTLs for high-speed service; this project failed, and the last RTL trainsets left reven ...

Tilting Train
A tilting train is a train that has a mechanism enabling increased speed on regular rail tracks. As a train (or other vehicle) rounds a curve at speed, objects inside the train experience centrifugal force. This can cause packages to slide about or seated passengers to feel squashed by the outboard armrest, and standing passengers to lose their balance. Tilting trains are designed to counteract this by tilting the carriages towards the inside of the curve, thus compensating for the g-force. The train may be constructed such that inertial forces cause the tilting (''passive tilt''), or it may have a computer-controlled powered mechanism (''active tilt''). The first passive tilting car design was built in the US in 1937, and an improved version was built in 1939. The beginning of World War II ended development. Talgo introduced a version based on their articulated bogie design in 1950s, and this concept was used on a number of commercial services. Among these was the UAC Turbo ...

UAC TurboTrain
The UAC TurboTrain was an early high-speed, gas turbine train manufactured by United Aircraft that operated in Canada between 1968 and 1982 and in the United States between 1968 and 1976. Amtrak disposed of the trains in 1980. It was one of the first gas turbine powered trains to enter service for passenger traffic, and was also one of the first tilting trains to enter service in North America. Description Chesapeake & Ohio design study A series of design studies carried out by Chesapeake and Ohio Railway in the 1950s used the second-generation Talgo design for their car suspensions. The suspension arms for each neighboring pair of cars were attached to a common bogie ("truck") between them, as opposed to having a pair of separate bogies for each car. The bogies rode the common curve between the two cars, centered by traction springs that centered the axle between adjoining car bodies. TurboTrain cars are lower than conventional cars, to lower the center of gravity in rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney Canada PW100
The Pratt & Whitney Canada PW100 aircraft engine family is a series of turboprops manufactured by Pratt & Whitney Canada. Pratt & Whitney Canada dominates the turboprops market with 89% of the turboprop regional airliner installed base in 2016, leading GE Aviation and Allison Engine Company. Development The engine was first introduced as a technology demonstrator in 1977. The PW100 was first tested in March 1981, made its initial flight in February 1982 on a Vickers Viscount testbed aircraft, and then entered service in December 1984 on a Dash 8 regional aircraft for NorOntair. The PW150 engine was introduced on 24 April 1995, when Bombardier selected the engine for the launch of its de Havilland Dash 8-400 regional turboprop. The PW150 was a higher-power version of the PW100 series, with the low-pressure compressor changed from a single-stage centrifugal compressor to a three-stage axial compressor, and the turbine modified to have improved cooling. The power rating was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Florida High Speed Rail
The Florida High-Speed Corridor is a canceled high-speed rail project in the U.S. state of Florida. Initial service would have run between the cities of Tampa and Orlando, with plans to then extend service to South Florida, terminating in Miami. Trains with a top speed of to would run on dedicated rail lines alongside the state's existing highway network. Construction of the line was slated to begin in 2011, with the initial Tampa-Orlando phase completed by 2014. On February 16, 2011, Florida Governor Rick Scott formally announced that he would be rejecting federal funds to construct the high-speed railway, thereby killing the Florida High-Speed Rail project. Governor Scott said the project would be "far too costly to taxpayers" and that "the risk far outweigh the benefits". In the wake of the project's cancellation, a private sector express passenger service running across much of the proposed route has been proposed by All Aboard Florida, now known as Brightline.

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] |
ViaFast
ViaFast (corporately styled VIAFast) was an abandoned passenger rail plan that would have cut Via Rail's trip times throughout the Quebec City–Windsor Corridor. ViaFast did not propose true high-speed service throughout the service area, but a series of smaller upgrades to avoid known bottlenecks and provide improved performance at a fraction of the price of entirely new lines. It aimed to reduce the Toronto Toronto ( ; or ) is the capital city of the Canadian province of Ontario.

Referendum
A referendum (plural: referendums or less commonly referenda) is a direct vote by the electorate on a proposal, law, or political issue. This is in contrast to an issue being voted on by a representative. This may result in the adoption of a new policy or specific law, or the referendum may be only advisory. In some countries, it is synonymous with or commonly known by other names including plebiscite, votation, popular consultation, ballot question, ballot measure, or proposition. Some definitions of 'plebiscite' suggest it is a type of vote to change the constitution or government of a country. The word, 'referendum' is often a catchall, used for both legislative referrals and initiatives. Etymology 'Referendum' is the gerundive form of the Latin verb , literally "to carry back" (from the verb , "to bear, bring, carry" plus the inseparable prefix , here meaning "back"Marchant & Charles, Cassell's Latin Dictionary, 1928, p. 469.).
