Reply to "MTH K4 engine derailing on Ross switch"

Thanks to all for the suggestions.  I removed the pilot and it did not make a difference.  It seems to me that the driver spacing (gauge) is ok.  The roller pickup doesn't seem to be causing any issue.  All of the rails through the switchesd are level and even.  I also checked the guardrail opposite the frog (particularly the spacing between it and the outside rail) and it seems to be fine.  The problem continues to be that the flange on the lead driver will sometimes hit the frog and climb over it, especially when the engine is pulling cars.  I haven't pulled the switches up because yes, that is a LOT of work, and I am not sure how moving them somewhere would help fix the problem.
