Stephanie Dobbs says she ran the design team for the monorail. However, the vehicle changes from being a regular bullet train to being a monorail. For example all but one exterior CGI shots show it to be a normal train, however all the interior scenes show it to be a monorail (the brake disc bursting through the centre of the car for example) See more
I got to warn you guys, if this gets violent, I'm gonna fight back.
Alfredo the Thug
You think you're gonna fight back?
All right, maybe fight back's a little misleading. I'll take the beating 'cause that's all you two amateurs are cleared to do. And then one night soon, I'm gonna break into your house and kill each of you in your sleep. Probably start with you, Alfredo. That way Steven here can have a few extra days with Marla and the girls. It's only fair.
