I'm cleaning up an old Athearn U30b for a friend who's getting into model railroading. It came with a burnt out motor but I fortunetly I have that on hand already. What I need though at the front and rear handrails, not the stantions, just the rails themselves. as well as the parts that go on the top of the shell. I'm not sure what they are, probably horns but there are tree holes. it's also missing the two air tanks that sit on the frame. Thanks for any help anyone can give.
