ROUGH CUT (NO REPORTER NARRATION)
STORY: Video from a closed circuit camera shows the exact moment a train crashed in Buenos Aires killing at least 50 people and leaving more than 700 injured.
The packed commuter train slammed into buffers at a station on Wednesday (February 22) morning, trapping dozens of people amongst the wreckage.
The tragedy comes after a series of train accidents in Argentina and will likely bring about a prolonged legal battle.
Argentina's government said they would join plaintiffs against Trenes de Buenos Aires (TBA), the company that holds the concession on the Sarmiento line where the accident occurred.
