Howdy! This topic recently came up in my discussions about coal operations, and I thought I would post it here to get some more input. My road is freelanced, so some of my rolling stock will get my own road name. Is there a general rule of thumb for how much of your roster should contain other road names? Meaning, if you're modeling the Nickel Plate Road, obviously a lot of your equipment is going to be NKP. But how much do you dedicate to other railroads? If your lines are located on the east coast, do you add more from the same region, then taper off as you head west?
