HIGH-SPEED Metro trains - more than three times as fast as existing services - will start running in November, a local constructor said yesterday.
The new Line 22 will connect downtown Xuhui District to suburban Jinshan District with trains running as fast as 160 kilometers per hour, said officials with Shanghai Mechanized Construction Co.
At present, Metro trains travel at between 50 and 70km/h.
Line 22 will run overground, and the constructor also announced that it will build dozens of underpasses beneath the Metro tracks for pedestrians and vehicles.
The 56.4-kilometer-long Metro line will start at the Shanghai South Railway Station, one of the city's major transport hubs shared by Metro Line 1 and 3, railway services and coaches. It will run past Minhang and Songjiang districts, with the final stop at Jinshan New Town, which neighbors Zhejiang Province.
The Metro project will make use of the current single-track Jinshan railway, an underused cargo rail line. Constructors will revamp this and add a parallel new track.
It is planned that future Metro rails will facilitate Shanghai-Hangzhou high-speed trains running between the Shanghai South Railway Station and Hangzhou in Zhejiang Province.
"Instead of having to use level crossings, people will find enough underpasses to easily and safely cross Metro Line 22," said Sun Jihui, a senior engineer with the constructor.
One recently completed underpass, near Jinshan New Town, is only 59 centimeters below the rail track. "We have applied state-of-the-art technology to excavate the underpass with no need to suspend the train traffic above," Sun said.
The new technology reduces subsidence and the impact on nearby buildings, the engineer added.
In a drive to boost public transport, by 2015 Shanghai aims to have a total Metro network of 600 kilometers. The current network is around 400 kilometers.
