AF Fastrack

[Plasticville Kid]

Having a issue with using AF Fastrack.  When my trains round into the curves, it sounds like my train has derailed and makes a horrible grinding noise.  But the traini stil on the track.  Is there anything I can do to reslove this problem?

It has been reported by some purchasers of 27"R curve AF FasTrack that the flanges run on the tie strips. This is apparently due to the molding/manufacturing process used. If you have some of these curves that could cause the noise you are hearing. This issue was apparently corrected in later production lots.
