Description:A train crash in Buenos Aires Wednesday has killed at least 49 and injured over 600 people according to police. The train apparently had problems with its brakes as it sped into a train station during morning rush hour, slamming into the buffers. The impact caused the second car to impale the first car. Rescue workers tried to pull people from between the crushed cars, but many were killed on impact. Hundreds were put on stretchers and sent to local hospitals.(1:28)
