A Sydney man has rescued his baby son from the path of a train after his pushchair rolled off a platform.

Mark Canty jumped on to the tracks at Riverwood station and threw the pushchair holding 10-week-old Conor back on to the platform.

He managed to wedge his body up against the platform as the eight-carriage train hurtled past centimetres from his head.

Both Mark and Conor emerged from their ordeal unscathed except for cuts and bruises, says the news.com website.

Mr Canty said: "I could see the train coming from a distance, and when I turned back around the stroller was rolling down towards the tracks. It landed upside down on the track closest to the platform after falling more than a metre.

"All that was going through my mind was that he was just a baby and I'm 41, so if anyone was going to die I wanted it to be me."

Mr Canty believes the strength of Conor's stroller was a factor in saving his son's life, as were the shoulder straps used to secure him. It was the first day Mark and his wife had used the shoulder straps.

ok, if i may give this one another shot...here we go:

I think it is so beutiful that a man would put his own life on the line to save a loved one. i wish that i could maybe do that for my child someday...not that i'd wish it would fall in front of a train or anything...

ok, that didnt go as well as i had planned...

Yeah,it was nice of him to save his child,notlike any other family would leave it there.....
