chunk: While following the runaway train above ground, Garber becomes convinced that it is a diversion and that the hijackers must have left it. In the tunnel, the hijackers begin their escape into the emergency exit; however, Grey refuses to leave his gun behind, resulting in a stand-off with Blue, who shoots him dead. The undercover officer manages to kill Brown (Earl Hindman) with one shot. Green escapes onto the street, while Blue shoots at the officer until he wounds him. Garber arrives and, drawing on Blue, orders him to surrender. Told that New York no longer has the death penalty, Blue electrocutes himself by stepping onto the third rail. Meanwhile, the runaway car finally encounters a red signal upon the approach to the South Ferry loop and grinds to a halt; the remaining hostages are safe.
