A Shanghai subway train has hit the rear end of another train, injuring at least 200 passengers, the train company says.

Most of the injuries were slight, Shanghai Shentong Metro Group Company said after the incident on Line 10.

It happened after signal system failure at one station, China's official Xinhua news agency reported.

The city has rapidly expanded its subway system in recent years and some lines have seen recurring problems.

Tuesday's incident happened near Yu Yuan station in central Shanghai at 14:51 - about 40 minutes after Shanghai Metro reported equipment failures on a train.

At the time of the crash, staff were directing trains manually, Reuters news agency reported.

One passenger said there was a lot of blood in the first carriage of the train.

Streets around the station were cordoned off to allow ambulances through.

A collision between two high-speed overground trains in Wenzhou, eastern China, in July killed 40 people and provoked public outrage about safety standards.

The country's safety chief said serious design flaws were to blame in that case.
