Dozens hurt in China subway crash

Dozens of people have been injured in a subway train crash in China’s commercial centre of Shanghai.

The accident happened when one train rammed into the back of another on Line 10, one of the city’s newest lines.

Local reports said it may have been caused by problems with the signalling system, similar to a crash in July on one of China’s high-speed train lines.

Shanghai TV said more than 100 people were taken to hospitals for treatment. The exact number of injuries could not be immediately confirmed.

Shanghai, a city of 23 million, has rapidly expanded its subway system in recent years. Some lines have had problems with faulty signalling, doors not opening properly and poorly trained operators.
