At least 36 people were injured in Buenos Aires on Saturday morning after a commuter train slammed into a station, almost reaching the turnstiles.
It happened at the Once station on the busy Sarmiento line.
Passengers described the moment of impact.
SOUNDBITE: Unidentified Passenger saying (Spanish):
"You didn't feel hard braking, the train was at the same speed in which it was coming. What I heard was the impact and then the lights went out."
This is the same station where 52 people were killed last year in an almost identical collision.
Local media say a mob formed here shortly after the crash and tried to attack the train operators.
