Perhaps there is some confusion as to how to use a gauge correctly?
The confusion is in Terry's mind, many many here have tried to tell him that we have NMRA RP25-110 wheels that quite happily go thru Peco points, he had continually stated that this can not be so because Peco points aren't NMRA compliant, then various standards were being dragged into the argument, fine scale wheels seem to be the big argument now, mud is being thrown around but nobody is giving in and double standards are being used (for your information Terry, I am quite well aware of standards and how they are used, I have been scratchbuilding in this hobby in various gauges for 40+ years, I build my own points in H0, H0n3 and gauge 1 so know full well what standards are for and how they need to be used, you should perhaps stand back and stop assuming that you are the ant's pants and accept that a lot of others in this big wide forum know their stuff as well).
I and many others have stated with total truth that NMRA wheels will go thru Peco points reliably, some have commented that in some cases the B2B may have to be tweaked, Terry jumps on that to say that "ha, you are not working to NMRA standards then", but we are still working within the NMRA standards tolerance, something that even he admits is in the AMRA standard (hence my double standard comment).
I for one will concede that Terry may be right about fine scale wheels and fine scale point work, I actually don't give a rats smeg, I am quite happy to run 'steam roller' wheels with Peco points, interestingly, my only fine scale engine is a Brass 520 class with Rp 25-88 wheels which has never to my knowledge derailed on any Peco points. I am not interested in fine scale so I haven't read your AMRA standard, I lay my own points to NMRA standards to run my NMRA standard wheels and by happy perchance, all my NMRA wheels run thru my Peco points, which is also good in that NMRA wheels are about as standard as you can get.
If I am doing something wrong, well so be it, I am happy, my trains run, on club layouts and others railways as well and vice versa, if you are having that much trouble running trains that you had to design your own standard Terry, I could have come around and show you how to lay track properly years ago and save you a lot of trouble.
But I do have one question which others have actually asked with no answer that I can find, if I was to embrace the AMRA standard, relay all my points and re wheel all my stock, where do I buy all those wheels that I will need, now I will need some replacement wheels for all my locomotives as well, my 520 is the only one I wouldn't have to convert, that is lucky???
But I will be doing this to correct a problem that I don't have, so I am not sure I can spare the time, I won't have time to count the rivets on all my rolling stock (you do that as well don't you Terry), yeah, I know, I'm slinging mud but what the heck, it doesn't seem to stick on Terry anyway.
Having re read this post I realised I do have to own up to my 520 derailing on a Peco point, actually 2 Peco points, a 3 way and a double slip, both very old, I have tried shimming them but I suspect the bigger issue is the tight radius thru these 2 points, we have problems with other stock as well.
