quote: Even though a French train holds the world speed record on rails -- 357.2 m.p.h. -- the Maglev holds the current overall record -- a maximum speed of 361 m.p.h. The only fully operational Maglev line is operating on almost 20 miles of rails in Shanghai.
quote: how there can be 20 miles of rails in Shanghai Maglev line?
quote: It'll be good to have these all over the world soon so planes don't need to be used so much.
quote: In the US we already have an electrified corridor (DC-Boston). However the problem isn't the speed of the trains: it's the congestion on the rails. The high-speed Acela spends most of its trip between DC-NYC well-below its top speed due to the rail congestion.
quote: The shinkansen lines are completely separate from other tracks although they often use the same right-of-way. In the Northeast corridor you will have the Acela, the Metroliners, regional rail, and freight running on the same rails and often at the same time. Again, the problem is not the quality of the rails, it's the congestion. The Acela, which can operate at well over 80 MPH often pokes along at less than 40 waiting for signals to change and other trains to free up the blocks.
