This is the shocking moment a level crossing pole clotheslined a motorcycle passenger as a train approached.

The couple were travelling home when the husband attempted to cross the tracks just as the barrier began to lower in Bangkok, Thailand.

However, his wife was struck by the boom gate.

CCTV footage shows the man ducking under the descending barrier while the woman was hit by the barricade, causing her to fall from the motorbike and land hard on the ground on April 22.

She was seen staggering to her feet, still in a daze from the powerful blow. Onlookers stood watching like lemmings, unsure of what to do next.

The motorist immediately pulled over and ran back to help her, managing to drag her off the tracks just moments before the train passed. The woman was then taken to the hospital for treatment.
