I can't answer your questions about ownership, but I do have a little information about how the guys worked. Sue Trotman, cureator of the Gosport Museum, told me this about her grandfather who was an RPO employee. He lived at Gosport, would deadhead to Louisville, worked two round trips between Louisville and Chicago, then deadhead home. She also said that earlier in his career he worked other roads out of Chicago until he had enough seniority to hold a route on the Monon. He may have worked between Chicago and Indy too. I don't remember for sure. / Ron
