Hey all...
I figured I bring this up, since it drives me personally crazy.
We occasionally stumble across a condition where locomotives make one pass over the loop just fine, and on the next pass they derail...
We do track inspections after every derail, but the track isn't out of gage, or kinked upon inspection. Everything seems tight, and when we rerail it the locomotive will could go the rest of the night without a problem, and if it does derail again that night, its not in the same place.
When the locomotive is taken off and checked for binding, there is no problem.
We've been aggressively conducting track maintenance, double checking for loose spikes and other "lack of maintenance" conditions, but the derails continue.
What could be the cause of this condition?? Its 2 rail, 1 1/4 inch gauge track, code 172 rail, flex track in the hard to reach places, hand laid everywhere else, including the switches.
Any help would be appreciated.
Rob
