Five teenagers ‘put their lives at risk’ with an ‘incredibly stupid’ selfie video standing on railway lines with their backs to a cargo train as it hurtled towards them, Russian police say.

The unnamed boys, aged 13 and 14, stood on a branch line of the Trans-Siberian route as the train bore down on them.

Their video shows them ignoring repeated warning signals from the driver to get off the track, reports the Mirror.

Instead, they laugh, joke, and wave defiantly at the train.

One boy remained on the railways - only fleeing at the last minute, initially ignoring demands from his friend to get out of harm’s way.

The video ends with the children running away from the scene on the snow y embankment.

The heavily-loaded train was travelling at about 45 mph before the driver applied his emergency brakes, finally stopping ‘a few metres’ from where the teenagers were making their video.

The incident was only 110 miles from a spot where last year two boys and a girl aged between ten and 13 were killed, and another seriously injured, after being hit by a cargo train while making selfies.

This led to warnings in the region nine months ago about the dangers to children from posing on railway tracks - which are often not fenced in Russia.

Parents and their sons in the latest incident at Rettikhovka village, near Ussuriysk, were summoned for a dressing down by local police.

An officer said they had been ‘incredibly stupid’.

In Moscow, Interior Ministry spokeswoman Irina Volk said the boys had ‘put their lives at risk’.

The children are too young to face legal sanctions over the incident.

But the parents face charges of ‘failing to perform their parental responsibilities’ - leading to a small fine and reprimand.

One unnamed mother said: ‘Thank God they are all alive.’

Another said her son had told her ‘it was just some fun’, reported The Siberian Times .

She had repeatedly warned her son before the incident about the risks on railway tracks.

‘I don’t really know why it happened in our family,’ she said.

‘So we talked to him and he promised it would never happen again.’

Last June three children Vladislav Khoroshinkin and Sergey Zembakhtin, both 13, and Sergey’s sister Ustinya, ten, were killed when making selfies on the Trans-Siberian railway.

One of the children’s body’s was sliced in half by the train.

Another girl Anya Khvatova, 13, suffered serious injuries after being hit by the train.
