I now have 2 engines,CNW RS-32 #4242 and CNW F3 # 4056. My dad suggested that we try to model a time period because he thought they really looked cool, and I did agree with him, modeled time periods are increadably impresive. However, I was planning on having a modern fictional idea (CNW never got bought out, Riverside RR is a shortline w/ leased CNW loco's, present day theming, make up more stuff to run any loco I want). I've read about some layouts that are fictional that were based off real historic events, and so that idea apeals to me, too. So in summary, What kind of layout should I go for: Period or modern fictional?
