Terry, What is so darn bad about the NMRA standards? They make it possible for everyone's stuff to more or less work together with out major modifications. I've used the NMRA standards for everything except sometimes car weight. Everything has run just fine so far. Your right about those Atlas turnouts though. My NMRA gauge says the ones I have didn't meet any standards. And when I made them gauge right they still gave me problems even after putting power to that mystery metal frog. At least my semi junk Walthers code 83's after about 20 minutes work operate like champs. Then I have my fathers scratch built turnouts most of which still work flawlessly after almost fifty years. Too bad they're brass. I remember how my dad and I would go through an hour long rail cleaning ritual when we wanted to run the trains or if guests were coming over who might want to see the railroad. My dad had some wheel sets he used as gauges to lay his track Everything operated fine but his track gauge was a tiny bit more narrow ( at least in the turnouts he built) than the NMRA standard.

Unfortunately MR continuesto push out of date second best NMRA standards and the to heavy incorrect NMRA weight RP. It also is corrupted by its need to support its major advertisers, resulting in info commercial style articles which results in some inferior products being widely used eg Atlas turnouts and track.
