Rensselaer Polytechnic Institute freshman offensive lineman Reuben Clarke's quick thinking may have saved lives Wednesday night.
According to ESPN.com, Clarke pulled the emergency break when he noticed two train cars detach from the rest of an Amtrak train in Rensselaer, New York.
Per CNN's Madeline Holcombe, passenger Helen Mary Crane credited Clarke with saving lives: "He saved our lives tonight. Our car broke off from the rest of the train and was picking up speed. There was no Amtrak personnel in our car. Reuben calmly went into action and pulled the emergency brake at the front of the car.
