Right, I've finally got some modules together, so I placed down some unitrack for inspiration:
and had difficulty getting the T-Trak HO standard required 1mm track overhangs. Measuring the module lengths revealed why, they're 1-3mm too long. There's a bit of unitrack in N Gauge (20-050
), which if it was available in HO would make that issue go away and I'd think would make trying to use #4 points less of a headache (#6's are pictured).
I'm also starting to see why there's more T-Track-N modules around then HO, as I believe that in that space an modeler in N would be able to create an functional layout.
