I think any kind of layout change is a good way to get re-inspired about trains, whether it's, the scale time period, or locale. It's all trains so it must ok. I was sort of curious why you wouldn't explore HO scale steam on this layout. Small steam switchers are where HO scale gets really fun. Come to think of it diesel critters are fun too. But you can actually fit sound into them in ho. Have you seen Bachmanns new 4-4-0?
