Frank: This ain't training. In training they just give you an F. Out here you get killed.
Connie Hooper: We're not just talking about a train here. We're talking about a missile the size of the Chrysler Building!
Inspector Werner: I thought you were in favor of derailment.
Connie: Yeah, when they were out in the middle of nowhere, not now. It's just town after town out there.
Oscar Galvin: Did I or did I not tell you to get 1206 off the main?
Connie: I asked them nicely.
Will: This is Will Colson, the conductor speaking; just to let you know we're gonna gonna run this bitch down.
Suggested correction: Not necessarily. Some engines may not have a rear cab access (like Frank/Will's engine had). And even if the rescue engine did have a rear cab access 777's engine only had a side access stair which at the speed it was going is more difficult to climb over from the engine in front of it.
Actually 777's catwalk goes across the front, from side stair to side stair, but someone would have to leap over a rail or a chain to get onto it from the other engine. Why would there be stairs on the right side unless there was a catwalk to get to the door on the left side?
