It's probably a tough question to answer, but is there a way to find out what railroads would typically be "prototypical" to run in a MU/Lashup? I model diesels from the 50's to current and pretty much any RR that appeals to me. I know we'd never see a Norfolk Southern running with a UP, but I'm curious which Railroads would get an OK to run in a MU lashup.
