Forgive me if I am showing off my lack of knowledge when it comes to railroads, locomotives, and the like- but I have a question I was hoping someone here could answer. Is the name "warhorse" used to describe any particular type of locomotive, in the same way as say "U-Boat" describes the Universal Series of GE locos? I've seen it used, usually on EMD GP series diesels, but I'm clueless as to what it actually means. Anyone know for certain?
