I have a list of alpha codes for UP, and I have a question. There's this train that comes through Butler, WI every Sunday with the symbol "PRITA". On my list, the "PR" stands for "Proviso", but I'm not sure where to go from there. Is the train from Proviso(PR) to Itasca, Wi(IT), or is it something else? If it is, what does the "A" stand for? Could someone help me learn how to read these train symbols. Thanks! P.S. If you see a train, is there any way you can tell what the symbol of that train is? ------------------ What's that? A train horn? Sorry, gotta go!
