Police in Shanghai have broken up two days of protests against the extension of the city's showpiece magnetic levitation - or maglev - railway (links below.)
http://news.bbc.co.uk/1/hi/business/7186924.stmhttp://news.bbc.co.uk/1/hi/world/asia-pacific/7188122.stmThe demonstrations were held by residents living near the planned extension, who are concerned at the possible noise and magnetic radiation.
Shanghai authorities have already revised the route to avoid the most densely-populated areas.
Super-fast Maglev trains use electric magnets to float above their tracks.
This allows for speeds substantially higher than standard railway lines, as there is no friction between the train and the track.
Last year, Germany said it had come up with the funds to launch its own maglev rail service.
The state of Bavaria is to build the high-speed railway line from Munich city centre to its airport.
The announcement sparked protests in Munich against the giant cost of the scheme.
Japan is also now actively exploring the introduction of maglev services.
