This is the moment a man running to catch a train ran headfirst into a huge concrete pillar in front of jeering passengers.
Open-mouthed and sprinting as the train pulls away from the platform, in dramatic footage the Philadelphia Eagles fan looks unstoppable and completely oblivious to what's about to happen.
A split-second later the unnamed man, dressed in the team's green jersey, is seen bashing his head as he smashes into the pole front-on in dramatic footage.
People inside the train shout and laugh at what looks like an extremely painful accident.
Unfortunately for him, the journey continues without him.
