Line 11 to boost safety with new signal system

METRO Line 11 will upgrade its signal system and use the most advanced technologies available to improve safety and prepare for shorter interval times between trains in the future, the city's subway operator said yesterday.

Testing will begin tomorrow and is expected to last 40 days, said Shanghai Shentong Metro Group, the operator.

Shentong said the communication based train control system, or CBTC, will help prevent accidents along the subway network, which will include 500 kilometers of track by 2012.

The city now has 420 kilometers of Metro track.

A signal glitch caused a train, which was full of passengers, to hit an empty one late last year. No one was injured.

Line 11 is the city's fastest with trains reaching a top speed of 100 kilometers per hour.

Lines 6, 7, 8 and 9 will also be upgraded to the CBTC platform soon.

The technology, which has been used on subways in New York and Paris, will enable Shentong to safely shorten intervals once more trains are added.

The operator also called for commuters to be patient as there may be delays during testing.

Meanwhile, thousands of armed police soldiers will no longer be stationed at the city's 200-plus Metro stations as of today. They were on duty at station entrances for the World Expo period. But bags will still be scanned, officials said.
