ITV said:There's warnings about the dangers of messing around near Greater Manchester's Metrolink after a boy was caught on camera lying down on the track.
A concerned passenger took the photo outside Wythenshawe Park station on the Manchester Airport line last month.
Metrolink say the boys stunt could have been potentially fatal and that his friends also risked serious injury by sitting on the platform edge with their legs hanging out.

I wonder if on the non-street running sections they should have a ban from people crossing the track and put bridges/underpasses in instead to be more like National Rail.
