An empty Amtrak train ploughed into the back of a commuter laden train near New York's Penn Station on Monday, leaving 130 people with minor injuries.

The collision occurred just after 7:00am (local time) as the packed commuter train, run by the Long Island Railroad, was waiting to enter the station.

"We are treating 130 civilians for minor injuries," said fire department spokesman David Billig.

"There are no reports of any serious injuries ... it's mostly just bumps and bruises."

The Long Island Railroad said an investigation had been launched into the cause of the accident.

Fire Commissioner Nicholas Scoppetta said more than 40 ambulances and 200 firefighters had been sent to the scene to help evacuate and treat passengers.
