Thunderstorm knocks out Metro stretch

A THUNDERSTORM yesterday caused a power glitch in the city Metro system that disrupted services on one line, the operator said.

A section of Metro Line 3, in the southwest of the city, lost power about 4:40pm during the rain and lightning, said officials with the Shanghai Shentong Metro Group.

The incident came just eight days after lightning cause a signaling malfunction that led to a collision between two high-speed trains in neighboring Zhejiang Province that left 40 people dead.

Although congestion was not serious yesterday, some passengers expressed their concerns online.

"Now small problems can unnerve passengers," said one rider. "It seems that the weather can beat any sophisticated technology."

Four stations, including terminal stop Shanghai South Railway Station, were affected, said the operator.

Metro officials said the trains "had to ride at a slower speed and the interval times were extended."

Passengers were advised to take other modes of transport. Services gradually resumed after the problem was fixed at 7pm, said Metro officials.

The Metro section that experienced the power cut yesterday is above ground, making it vulnerable to lightning and rain.

The power supply to the Metro system works in a similar way to that to bullet trains, although Metro trains travel much slower.

In 2008, services on Line 3 were halted for an hour after the line was hit by lightning.
