Hi Group,
I thought I would throw this out to the group, before I PM flyer nut, PHD/AF. I recently started running a 21085 that has a derailing truck through my switches at low speed. This is most prevalent in reverse with the switches "straight." I can see a small arc at medium speed through each switch. If I go slow, in reverse that truck will derail and short. That truck appears to be "factory" and not an "add on." All of my other steam and diesel locomotives move through these switches perfectly in both directions. There could be an obvious problem to the trained eye, but I cannot see it. Maybe someone on the Forum has seen this issue.
Thank you.

Do the dime test. Check the gauge of the wheels. Can't think of anything else
it could be. Dime should barely fit between wheels.

Trailing truck, 21085

Thank you Mopac for the quick reply. I did the "dime" check and that was fine. However, I studied a picture of a 21085 and noticed that the trailing truck looked a little different than mine. Sure enough, at some point in it's life, that trailing truck was installed upside down. I made that change and it runs perfectly. I always preach-"Simple, First." I did not follow my own advice. I went to a train show yesterday looking for a "find." Very unsuccessful. Fewer vendors, fewer AF. What AF that was there was overpriced and incomplete. I will do more research before I post an issue next time.

Glad you found problem. Sometimes it is so simple. LOL, so simple we can't see it.

So no more derailing?

Nope! No sparks, arcs, derailing and storing the Pepto for the next episode.:smilie_daumenpos:

Boy mopac ain't that the truth. The old adage of "can't see the Forrest for the trees". Been there, done that more times than I care to remember. That is why I walk away when I have an issue. When I go back with fresh eyes the problem is right there where it was all along!!

I for one appreciate your posting about the truck. I run post war O but have repaired 4 S gauge flyers for a friend. He has no desire or tools to attempt repairs. I found the information here very useful. I read the posts 5-6 times a week. Where I live (Western Ne) S gauge is very scarce. O is hard to find but S even more so. Thanks to all of you who share your knowledge.
