the orange car, for all of the non-railroad guru's, is a Bethlahem 89' flush-deck trailer flatcar. I got the car for my birthday on november 10, 2008. If you were HO scale (which you're not), and were standing on the middle of it, it is so long you could see the outer rail on one side, and would be floating over grass on the other.
here's some basic operation on the terminal.
