I have mentioned this problem in the Coffee House, but would like to do a separate Thread regarding this problem. The locomotive is an Athearn SD-39, six axle locomotive. At only one point on the layout when the SD-39 is going around a 24 inch radius curve will the front lead wheel set on the front truck derail. It is always in the same spot and only with this locomotive. I've run other six axle locos through this curve for hours without a problem
I've check the trucks' wheel gauge, freedom of motion of the trucks, the track gauge, ballast interference and the wheel sets' play in the trucks. If the locomotive is run back wards through the curve everything is fine.
This problem is really getting to me!!!
Any suggestions?
Thanks.
