A personal H0 layout growing step by step.
I’m John Jorna. I am building my own layout with Märklin K-track, track helices and a hidden yard. Blocks, feedback and automatic running are part of that project. With SpoorSlim, I want to make that approach clear for other builders: plan first, measure next, then test.
Personal photos show my layout under construction. The 3D view is a design. My K-track, ECoS and iTrain approach sits alongside explanations for other systems.
