Maglev
The world's first commercial maglev system was a low-speed maglev shuttle that ran between the airport terminal of Birmingham International Airport and the nearby Birmingham International railway station between 1984 and 1995. Its track length was , and trains levitated at an altitude of , levitated by electromagnets, and propelled with linear induction motors. It operated for 11 years and was initially very popular with passengers, but obsolescence problems with the electronic systems made it progressively unreliable as years passed, leading to its closure in 1995. One of the original cars is now on display at Railworld in Peterborough, together with the RTV31 hover train vehicle. Another is on display at the National Railway Museum in York.
List of maglev train proposals
San Juan – Caguas: A maglev project has been proposed linking Tren Urbano's Cupey Station in San Juan with two proposed stations to be built in the city of Caguas, south of San Juan. The maglev line would run along Highway PR-52 connecting both cities. According to American Maglev Technology (AMT), who is the company in charge of the construction of this train, the cost of this project is approximately US$380 million.
