I'm thinking about adding an Nscale Athearn SD75i in Ontario Northland colors (O-N) to run with my CN and CP diesels. I've never seen one here in the Carolina's (but that hasn't stopped me from buying other diesels of various road names before) but I was curious...does (or did) O-N normally run with CN or CP trains? Or did they stick primarily to their own rails and routes? I've found only a few pictures of O&N SD75i units running with other railroads and wondered if there was some bigger corporate reason that they weren't not seen much attached to other CN or CP trains. Also, do they ever get into the US on CSX lines or other New England routes? Thanks!
