He reaches for the emergency brake but it's too late. He's going to crash. A screech like a buzz saw cuts through his ears. Lights go out in the car behind him. Bodies whiplash against the sides.
Voices cry out.
In the nearing distance, he sees people backing away from the edge of the platform. They're thinking subway crash. They're thinking bits of twisted metal, torn concrete, and body parts found among the debris. They're thinking last moments before life slips away amid terror and confusion. But at the last possible second, he throws the brake and the mechanical track arm hits the trip cock on the undercarriage.
