Model Train Scales Explained: HO, N, OO and O
HO scale is 1:87 on 16.5 mm track. Every common model train scale from Z to G in one table, HO against N for a first layout, and how Traluno uses HO.

Why Tight Curves Break Voxel Track
Traluno's track has one curve radius, 5 units. Why a swept box breaks below a minimum radius of its own, and how that compares with real HO curves.

The Loading Gauge, or: Why the Crane Ate the Train
What a loading gauge is on a real railway, the one number every Traluno model over the track must clear, and the crane a goods train drove through.
