Hello again, i'm having a kind of problem here: I'm sorry about my ignorance... but how is a freight train? I mean, locos, i know... But what about freight cars? - Is it normal to have freight cars from Burlington Northern and also from ATSF? - And can I have ballast hoppers, box cars and gondola cars in the same train? - Sorry to ask, but what is a caboose? Should I have one? Can you guys show me a site here I can get some info about this? or some examples. I really would like to see, but model websites world be better!!! sorry for the dumb questions, but I need to know this.
