Shanghai mayor warns for subway safety

Shanghai's mayor Han Zheng is warning for safety problems at the local subway, says Reuters, quoting the China Daily.

With work scheduled this year on seven new and existing subway lines, the city's traffic would face "tough times", the China Daily quoted Mayor Han Zheng as saying.
"With so much work being carried out at the same time and long lengths of new tracks being put into use, both the construction and operation of Shanghai's subway have reached an extreme level," Han said.

In a country where government officials mostly do not say anything or when they talk often downplay potential dangers for its citizens, this is a bit of a troublesome message. Wonder what the fallout is.
