A 14-year-old boy suffered serious injuries when he jumped onto a railway line at a Midland station yesterday.
The teenager triggered delays of 90 minutes as the line was closed and paramedics were called to Lea Hall station, Birmingham, at 4.30pm.
The youngster, who has not been named, was taken to Heartlands Hospital.
Virgin Trains, which travel through Lea Hall on their way from London to Birmingham, said the teenager was lucky not to have been killed.
Jim Rowe, from Virgin Trains, said: " This was disruptive to our trains and our service in general.
" We apologise for the inconvenience caused. We would issue a warning not to go near railway lines. It is very dangerous.
"Many people are killed every year playing on railway tracks. It is tragic for their family members, those who have to deal with them afterwards and for the drivers of our trains.
" This youngster was extremely lucky not to have been killed. His experience serves as a warning to the general public to stay away from railway lines."
