Hi Greg,I would ask you to read my page and see after reading you agree with my logic and assessment.
I don't want to get in a pissing contest over this but I do have a couple of comments.
1. Let me begin by saying despite gauge 1 track existing before Lehmann came out with their "Gross Bahn" it was Lehmann's release of the "Gross Bahn" in the late 1960's that really popularized garden railroading for the masses. Primarily because of size - 1:22.5 scale based loosely on narrow gauge prototypes, the price - it was much more affordable than other existing large scale trains, it was well made and fact that it worked.
2. LGB models are hardly what we would call fine scale and neither is their track. LGB is renowned for their "rubber ruler". These are compromises designed to make the trains very robust so they can withstand the rigors of being played with both indoors or out. LGB trains are "toys" in this sense.
3. LGB engineered their model trains and track to work well with each other, particularly outdoors. They succeeded stunningly as can be judged by both their popularity and the major copycats that sprang up - Aristocraft, Bachmann, and Hartland Locomotive Works for instance. Even though these manufacturers came out with their own track systems they were all pretty much based around LGB's track design and rail size, code 332, as the standard.
I think most on this forum (dare I say even you?) would agree with the above.
LGB wheels and track (read turnouts) don't meet the NMRA/G1MRA standards. Not even the "Toy Train" NMRA standards you rail against (pun intended). Also, the earlier G1MRA standards on which the NMRA standards are loosely based were actually intended for the 1:32 scale not 1:22.5. LGB wheel flanges are too wide at the root - I measure around 1.98 mm and too deep at 3mm. Turnouts have flange ways that are far too wide at the wing rail as compared to the 3mm standard. Depending on the turnout (R1, R3 or R5) more than double. I measured 6.3 mm for the diverging route wing rail flange way at the frog tip on a R1 turnout. R5 flange ways at the frog tip measure around 5mm. The guard rail flange ways are closer to the standard at around 3.5 to 4 mm. I'm sure part of the reason for the "discrepancy" are the thicker than "standard" flanges on LGB wheels. In any case, LGB wheels and track work very well together. To expect LGB to significantly modify their designs to meet "standards" promulgated 40+ years after the craze they pioneered is, I feel, disingenuous.
I do, however, recommend people read the free to view Garden Railways Magazine series on these issues (In addition to your very helpful website): https://grw.trains.com/~/media/files/pdf/rapid/understandtrackandwheelstandards.pdf
In the end the point of this thread is to help Jim solve his derailment problem. Hopefully, with everyone's contribution, we have!
