Sometown? Anywhereville? Imagineby?
I feel your confusion, I absolutely suck at naming imaginary routes, so I try as much as possible to replicate real routes. Or if I have a fictional project, I name it after where it is, like "Idaho Narrow Guage". I don't know why I got Idaho, but somewhere mountainous in northern United States, nowhere near the coast. And don't say Sascatchewan! Oops, that's Canada!:hehe:
Or sometimes I name the route after the company operating it, eg "Canadian Pacific" or "New York Central" (which I deleted and renamed Northeast Seaboard)
I hope this solves your issues,
