BUILDERS of the city's Metro system said they are using a new power-supply technology for smoother subway operations on the under-construction Metro Line 16 stretching into the suburban Pudong New Area.
Unlike the overhead grid network commonly seen at other Metro lines in the city, Line 16 will have an extra contact track used to supply power to the subway trains.
Dubbed as the "third track" paralleling the train track, the grid track is easier to install and maintain, according to the local Metro authority, Shanghai Shentong Metro Group.
"It can also stand outside environmental influences like winds, thus decreasing the threats of power glitches," said Metro officials. The track mainly works on high-speed subway lines.
Line 16 trains will travel at speeds up to 120 kilometers per hour, which would be the fastest in the city. The first train will be delivered to the city for testing soon and the line is expected to go into trial operation next year.
Shentong said that "during daily operation the speed will not reach the top out of safety concerns."
Most of the construction work of the 59-kilometer line has been finished, with station equipment installation underway. The line, with its 13 stations, including 10 at ground level, will link Longyang Road in Pudong with the seaside town of Lingang in the southern edge of the district along the coast.
The train's seats will be set in rows like those on railway trains, which will add about 20 seats on each carriage compared with the configuration on other lines.
By 2014, the city, with world's longest subway network, should have 14 lines with a network extending to more than 500 kilometers of track.
