Please forgive me if my terminology is sloppy. I've not found anything on what can be done with model trains other than running them around the track. I'm wondering...with available scale equipment can you build up a train from cars in a way similar to protoype operations? Now, I don't know how that's done in real operations, but I'm just wondering what 'railyard' activities can be simulated using scale gear. If my question even makes sense and the answer is yes, does it take the most sophisiticated & expensive stuff to do it? If you know of a book that focuses on this, please advise! Thanks for your patience, folks.
