Why pitch it!? You could make it into a non-powered loco. OR, use it as a really nice weathered old loco either as a "prop" or use it in a train - going to the scrap yard. Just remove the "guts" so it rolls freely. There's lots of things you can do with this old unit. Just because it doesn't run anymore isn't a reason to throw it out.
