Great topic and I’m enjoying reading about everyone’s railroad. I have always called it “the layout”. Here is a quick resume:
Name: Smithville & Western. It models a small railroad town in the fall, located in central Indiana. Besides a town, there is an engine terminal with turntable, roundhouse and locomotive shop.
Trackage: Primarily Lionel FasTrack with a yard area made with Gargraves. Curves are O-72 as a minimum. I had to give up a second mainline for the wider curves, but I wanted to be able to run scale engines.
Motive Power: Primarily steam but a few diesels too. Predominantly Fallen Flags from Indiana- NYC, PRR, Monon, NKP and Wabash. As a result I try to stick to modeling the 1950’s, but a few modern scenes have crept in.
Controls: DCS, Legacy and conventional- all controlled by an MTH Z-4000
