There is a low speed maglev train in Nagoya Japan called the Linimo, as well as a high-speed maglev train called the Shanghai Transrapid which links Shanghai International Airport and a transit station in Shanghai, China. There are also experimental maglev test lines in Daejeon, South Korea; Yamanashi, Japan; and Power Springs, Georgia, United States. A test facility in Emsland, Germany also just recently closed.

The maximum speed of a Maglev (magnetic levitation) train on a test track in japan was 581km/h.

In Shanghai, a Maglev train routinely runs to the airport at 431km/h.

Maglev by far, based in shanghai china

It's in China! Basically it' s a maglev train going up to 431 km/h in service and hitting 501 km/h on tests! It's a 30.5 km line between Shanghai and Shanghai airport. ;)

The Chinese city of Shanghai is reported to have a Maglev train in commercial use. The Japanese and Germans are working on Maglevs so are the USA.
