Title: PA's derailing
Post by: Richard1 on September 16, 2010, 12:11:46 AM
I am having trouble with my Bachmann PA's derailing, in spite of the fact that I have 32 radius curves. I have a feeling that something is wrong with the truck wheels as I don't have a problem with other six-axle engines, including running E-8's back to back.  I think the PA wheel flanges are wider than the E-8's.  How do I correct this? I don't want to rebuild the entire railroad just because I'm having trouble with two locomotives. Should I file down the crossover frogs somehow?

As far as I know, Bachmann did not make any PAs, are you sure they aren't Proto 2000.

have you checked the wheelsets with an nmra guage? that would tell you for sure it they are the problem.

that said, the athearn pa's are notoriously picky on track. they will find the flaws in it better than any other diesel. if their wheels are properly guaged, they will find things like high and low rail joints, joints that are slightly misaligned, and places where the track is out of guage. once you have eliminated wheel guage as a problem, you can use them to perfect your trackwork.

Dear Richard,
In fact, we have never made PAs. Checking the gauge is an excellent place to start.
Have fun!

I have a couple PA's from an old Athearn run. You sure they aren't Athearn? If they are, I can help you with that.

Cheers,
Joshua
