Regarding the Shinohara Sn3 trackl there seems to have been a 'shift' in the standards.? The recent stuff is fine 'as is' and all my stock on Rhyd runs through it quite happily - although the frogs need regular cleaning for good pick up for short wheelbase locos.? The older points were tight over check rails but it was a matter of moments with a 1mm thick needle file to open them out.? These, too, now give faultless running (and the frogs can get away with less cleaning!)
All my curves, under about 42" radius, have the gauge widened to 14.2mm anyway.? Russel will haul a train of bow-siders around a 24" curve with no problems although Lew struggles below a 28" radius curve - but that is more to do with pony truck clearance than gauge!.

Hi Craig,
I have had a go at comparing the NMRA standard at: against the O14 standard at:
It looks like the O14 back-to-back (min 12.4mm) will easily clear the Sn3 max Span of 12.01mm (.473") and the Sn3 C (CN in O14 terms) min of 13.18mm (.519") just exceeds the O14 C (13.1mm max) thus it all should work.
I would be grateful if someone could check my calculations.
