If I had unlimited space, budget, and time… I think I’d go for a sprawling, double-deck mainline that winds through realistic mountain scenery, dips into deep canyons, crosses massive bridges, and connects to gritty urban scenes with fully lit buildings and animated details.
But I’d want it to be more than just eye candy—I’d build it for operations too. Freight yards with working hump shunting, passenger stations with timed schedules, industries to switch. Maybe even hidden staging yards to simulate trains coming and going from the “rest of the world.”
And of course, I’d include a few whimsical scenes tucked away—maybe a hidden fantasy branch line with steampunk locos and oddball structures, just for fun.
What about you? Would you build something prototypical, completely fictional, or a mix of both?
