The five-months-pregnant woman said: 'It seemed to take ages for the train to arrivea nd when I thought I heard something, I leaned out onto the platform to see if I could see it in the tunnel. I just toppled over.'
'It was a combination of being tired and having more weight than I'm used to - and suddenly I found myself lying in front of the train. To say it was terrifying would be an understatement.'

Mai managed to crawl out from under the train unharmed, and was helped back onto the platform by other commuters. Her and her baby were later given the all clear at a hospital in Beijing.
A spokesperson for the Chinese metro system praised the driver for managing to stop the train so fast. 'I dread to think what would have happened if the driver had not acted so quickly,' they said.
