The planners of the Shanghai-Hangzhou magnetic levitation (maglev) rail project will design the proposed route to avoid residential buildings and lessen the impact of radiation upon people, according to a municipal government official.
“The maglev project has basically two environmental effects: noise and magnetic radiation,” said Zhang Quan, deputy director of the Shanghai Environmental Bureau.
A maglev train generates high levels of noise at speeds exceeding 200 kilometers per hour. “A possible solution for the noise problem may be slowing the train in downtown areas and speeding it up when it leaves urban districts,” said Zhang.
Approved by the central government in March 2006, the 175-km Shanghai-Hangzhou maglev rail project is estimated to cost 35 billion yuan (4.5 billion U.S. dollars). Trains will be able to reach a speed of 450 km per hour.
