RE: [CBQ] HO scale model need

["Steve Haas" <Goatfisher2@comcast.net>]

John commented in part:

<<I have an IHC ore car whose RP 25 contour wheels simply do not like 
Shinohara turnouts. They want to take the diverging route every time. All 
other models negotiate the switches just fine.>>


And Pat responded:

<<Have you checked the gauge on the wheel set?  Usually when a particular
car derails, it is a gauge issue.>>


I'm with Pat on this one.  Deeper flanges aren't the answer. As Pat
suggests, check the gauge on the wheel sets, and also use your NMRA gauge to
check the critical dimensions on the turnout, too. In particular, check the
guard rails on the stock rails to make sure they are properly positioned to
keep the wheel going through the frog away from the point of the frog so it
_can't_ pick the point of the frog.

All a deeper flange is going to do is do a better job of picking the point
of the frog.
