A couple were filmed having sex in front of shocked passengers on a moving train.
Footage taken by a shocked passenger shows a young woman kneeled in front of a man on a train in the city of Nizhny Novgorod in western Russia.
They appear to be having sex, with her sitting on his lap as the train approaches Chkalovskaya station.
The couple pause as the train stops and a passenger gets on carrying a black bag that he puts on his lap.
The bag partially obscures the camera’s view but the girl can still be seen bouncing up and down on her partner.
At one point the couple seem to notice they are being filmed but laugh it off and carry on with their lovemaking.
The passionate session ends at Moskovskaya station, where the girl pulls up her trousers still with a cheeky smile on her face.
Shocked internet users in Russia shamed the couple with one writing: ‘Why did no one come over and stop that?’
Police declined to comment.
