A couple who chose to have sexual relations on railroad tracks were run over by a passing train.

The pair decided this was the best way to “spice up their sexual life” but the decision had tragic consequences.

Authorities in the Ukrainian city of Zaporizhia say the 41-year-old man and his thirty something girlfriend "failed to overcome their natural passion...and wanted to experience an extreme sensation near the railroad tracks."

They were visiting a friend on Friday night and on returning home, things quickly turned romantic. Both are believed to have been under the influence of alcohol at the time.

Disaster struck when the couple failed to notice the train,a switcher locomotive model, heading straight for them.

Zaporizhia is the city where the tragedy took place

Ukraine’s Interior Ministry said the woman was killed instantly but her male companion survived. He lost both his legs and is currently hospitalised in a critical condition.

Gawker reported that the local news outlet said that the man will be charged with violating the country’s rules regarding safe railroad usage.
