More than a 1,000 protesters demonstrated Sunday against the planned extension of the transrapid train system in Shanghai.
The protesters, demonstrating in the city centre near a popular shopping district, were finally dispersed by police.
Sunday marked the second day of protests by residents living near the proposed extension route of the "magnetic levitation" or maglev train, which they fear would cause health problems from electromagnetism, as well as noise and tremors.
Local officials deny any possible health risks from the maglev.
In addition, residents fear the maglev train would lower the value of property near the route.
On Saturday, a larger number of demonstrators picketed in front the city hall. In this incident as well, police dispersed the protesters, piling them into buses.
The planned extension is for a 31.8-kilometre stretch to connect with Shanghai's second airport Hongqiao. Currently the world's first commercial transrapid connects the Pudong airport with Shanghai city centre. ( Dpa )
