Yes you are right. I can go with steam engine and older style cars. I will use an electric trolley engine on the second track. I just have to rid the new Porsche mini van & BMW car and get a early 1900s car or perhaps a few horses for the older vintage set up with the steam engine.As I said in the other thread, On30 is going to be a lot harder to find what you're looking for than either O or HO. You have to gauge your expectations a bit differently when you go with a less popular scale.
That's a good point, never thought about it like that.Maybe I've missed some history, but wasn't nearly all of the narrow gauge railroads replaced by standard gauges decades before the first diesel was ever built? I mean sure, some narrow gauge has survived, we have two running 36" railroads near Denver in the Rockies, but even the *idea* of a diesel running on narrow gauge seems completely alien to me.
