The Bombardier JetTrain was a project by Bombardier Transportation for a high-speed train that could be used in North America and that was based on the Acela Express and could have been used on routes without contact wires . It was the only vehicle the traction unit constructed of a gas turbine has as main drive. After a few demonstration drives at the beginning of the 2000s, the power car was moved to the Transportation Technology Center in Pueblo (Colorado) .

history

In the late 1990s, the United States Department of Transportation wanted to identify technological opportunities that would allow the gradual introduction of high-speed travel in the country. In addition to the development of a train control system , suitable level crossings and track systems , the Next Generation High-Speed ​​Rail Technology project also included the construction of a catenary-independent locomotive for high-speed traffic . The PPP project had $ 26 million available for research and development, half of which was taken over by Bombardier. The cooperation was agreed in October 1998.

In late 2003, a consortium of Bombardier and Fluor Corporation was named the preferred bidder for the development, construction, operation, maintenance and financing of the first phase of the high-speed network in Florida. From 2009, JetTrain trains should run between Tampa and Orlando.

technology

The JetTrain could have been used in various configurations that would have been equipped with one or two power cars and with cars with active tilting technology . Both trains with one powered end car and four to seven cars, as well as trains with two powered end cars and up to eleven intermediate cars were planned. The vehicles were based on those of the Acela Express.

Power end

Driver's table of the JetTrain power car

The power car is the only vehicle that was built. The car body and bogies were taken over by the Acela Express. The drive was provided by a ST20- gas turbine from Pratt & Whitney . The turbine was derived from the PW150 type used in regional aircraft , with diesel being used as fuel. The turbine drove a generator via a gearbox, which supplied the water-cooled IGBT converters with energy. At low speeds, the turbine was switched off and the power was supplied by an auxiliary diesel engine that drove the generator via the gearbox shared with the turbine.

dare

The cars would have been similar to those of the Acela Express and would have had hydraulically operated tilting technology, which would have inclined the car body in the curves by 6 ° to the inside. First ( business car ) and second class ( coach car ) cars as well as a bistro car ( business car ) were planned. The cars would have had a uniform length of 26,645 mm and would have weighed between 57.6 and 59.9 t.

Trial and demonstration drives

The power car with the number 2002 was completed in summer 2000 and reached a speed of 251 km / h in summer 2001 on the test track of the Transportation Technology Center . On October 15, 2001, the JetTrain was unveiled to the public at Union Station in Washington, DC . After an advertising tour through Canada in the spring of 2003, a demonstration drive to Florida followed in October 2003 , where the power car was presented in Miami by the Finnish racing driver Mika Salo . After the project in Florida failed in a referendum and the project in Canada also did not make progress for financial reasons, the JetTrain disappeared into oblivion.
