Bemo · H0m · 12 mm
Bemo H0m: track planner from your own stock
14 items with checked geometry. Enter what you own, let the Auto-designer lay ovals and other loops, and view it in 3D at your table size.
Metre gauge H0m: 1:87 scale on 12 mm, modelled on the Rhaetian Railway (RhB).
Bemo publishes no track spacing, and turnout plus counter curve comes out at 22.5 mm, narrower than a coach. That is why parallel track, passing loops and double track are switched off for this system. The Auto-designer still lays ovals and other loops.
