#1 is the point rail point…itself.
#2 is the point rail pivot, which is unlike anything that the prototype uses.
#3 is a guard rail meant to guide wheel flanges tight to its rail so that the other wheel doesn’t hop up over the frog and derail.
#4 is the frog area, but your pen seems to be closest to the frog point. The rails on either side of the frog point are also guard rails, but they are part of the point rails, as you can see when you trace them along their lengths.
#5 is the side of the gauge that shows if your wheel flange paths are clear for NMRA RP 25 flange depths. It is only an approximation for track gauge…not a good one, either. You want to use the opposite end of the track gauge to the one you show in this picture to test your track Your wheel flange gauge is on the right side of the NMRA gauge as you show it. The flanges should fit in the grooves.
#6 has the points gauge in the frog, so it is misplaced. You should only use the points gauge between the inside of a closed point (where it lies against its stock rail…the outside-most rails of the turnout) and the inside of the appropriate stock rail that the other wheel will ride when that point is closed.
If the rolling stock does not cross the frog assembly without derailing when it enters the points end of the turnout, chances are the wheels are not in gauge or their flanges are too large for the depth of the turnout flange-path. I assume that the frog is in good condition, not having been corroded or distorted by pressure and lots of use.
Ken, I too have had moments when I quite literally broke into a dripping sweat when building my track, making turnouts, finding derailment problems, finding shorts and circuit breaks, finding why my decodered locos won’t respond to commands when they did the day before, etc. You MUST stop, step back, and think a bit. It necessary, go peel some spuds and wash some dishes while you ponder your
