Got it and thanks! I’ll digest it, and then I think it would be fun to have a “track and wheel” thread.
The goal would be to discuss things about workable dimensions.
Maybe with all the brain power on this site, we could come up with some good ideas.
The first thing I do is read the stuff, and look for things that don’t make sense… I’ve been outside all day nursing a sick loco, so only got a few minutes to look at the translation, but it seems that the standard allows flange bearing frogs too, and then “modifies” things to allow this.
Wow, this could get complicated.
I spent some time looking very carefully at my switches, I only have Aristo, so that’s all I will comment on.
The Wide Radius switch can be made almost perfect, the frog is almost right to work properly, and you can shim the guardrails properly and you can deepen the wing rail flangeways. After these mods, it might be as good as something made to loose standards as it can be.
My #6’s are a big disappointment. The frog is just plain unworkable. There is no way to fix the fact that the frog point does not extend enough. Wheels will drop into the frog no matter what you do. Modify the guard rails to something more reasonable, like .106 and the wheel drop is minimized, but it there to stay. Only the gentle angle of these switches saves them. The frog flangeways are so deep, nothing will keep this from happening. The only salvation may be shimming the flangeways to make it a flange bearing frog, but then you have all the negatives of this design.
Well, it will be fun.
