I'm new to the forum and thought I'd share my 3min video. It's the first chapter of a series on building a small (coffee table) sized N-Scale layout. I'm by no means an expert (the opposite really) - this just collates some of the things we've been learning along the way.
This video covers the design process and talks about some of the challenges around gradient and radius for a small layout. But I'm just the guy with the camera, my boys are running the show
