One more thing: I try to keep costs under control by purchasing early postwar that is in good working order, not mint, and limit my pricey modern to just a few.
For instance, I have no Visionline and only 1 Legacy. My Legacy is a $750 NY Central 10 wheeler with whistle steam, which is the perfect locomotive for my layout that has features in common with The Put.
I have no plans for purchasing any more Legacy.
Would I love a Visionline steamer that has steam/smoke coming out of every crevice and runs well on 031 curves? Absolutely. But, if I ever get one, it will be my 1 and only Visionline to keep costs under control.
