... track" in it that would act like a long flange. But it does not give the accurate dimensions/measurement for checking there distance or clearance. My caliper can tell me a lot, would that not be a option? Or a simple 4 wheel boogie? Or did i missed your point completely? Thanks for reading and sharing your knowledge, Best Igor posted: 11 Sep 2020 21:50 from: Martin Wynne Hi Igor, You can see the dimensions for each track gauge setting in the Templot gauge list: 2_111634_520000000.png For your P-32 gauge, the flangeway gap is 1.5mm, which means the check gauge (from the V-crossing to the check rail) is 43.5mm. That flangeway is very close to being exactly to scale from the prototype, and P-32 is intended for hand-built locomotives with narrow lathe-turned wheels. I suspect that 1.5mm is too narrow for commercial and live-steam Gauge 1 models. You should probably be using 1C or 1F instead, with wider flangeways, for those models. ...
