cars falling off

hi i have a certain cars that keep falling off the track. do the wheels wear out to cause this?

Check to make sure the flanges are the same width as your other rolling stock.

It could also be a wight issue if it's too light.

Which brand cars?  What scale?  What kind of wheels? (metal? plastic?) What style couplers on the cars?  What style trucks?  Where are they falling off the track?(curves?  turnouts/switches?  rerailers?  straights?  elevation?)  All cars?  Some cars?  "Falling off" in the same place each time?  Going forward? In reverse?
