A teenage girl was killed by a freight train as she tried to take a selfie at the side of the tracks .
Karina Baymukhambetova, 15, was struck by the train at the weekend in Orsk, Russia.
She was reportedly "cut into pieces" in the horror.
An unnamed boy with her - a relative - managed to jump free from the track.
"The train driver spotted people on the railway line and sounded his horn,” said a local media report.
"He applied the train’s emergency brakes but failed to stop the train in time to avoid a tragedy.
"The boy managed to jump away.
"But the girl was not so lucky and was hit by the train which cut her body into pieces."

Devastated friends have paid tribute to Karina online.
"We remember, we love, we grieve," wrote one pal.
"Such grief. How her mother cried, my heart almost broke into pieces, so awful," added another.
Karina's heartbroken mum Natalia, 39, has received an outpouring of messages of support on social media.

A decision is to be made soon on opening a criminal case into Karina’s death.
Since the tragedy, Denis Khnykin, transport police senior youth liaison inspector, said: "I ask you to pay your attention once again and to warn your relatives.
"Please remind them of the fact that railways are dangerous both for your health and life."
But in recent months two 14-year-olds suffered electric shocks in separate incidents after trespassing on rail tracks in Russia.
Elena Zaporozhskaya, Orsk social policy chief, said: "Children need to be able to say ‘no’ when something is risky for their life and health.
"It is a hard thing to learn but necessary.
"Secondly, I want parents to know where their children are and with whom they are spending time.
"People must protect the lives and health of their children."
