QUOTE: Originally posted by selector Congratulations!. I would have suggested that you find how much side-to-side arc the coupler was allowed by the bolsters or the steps. In my case, the insides of the steps restricted the coupler too much, so I did the nasty thing and carved away some of the plastic. No more problems.

QUOTE: Originally posted by cwclark what i've done to my SP Sunset passenger train is to put a long kadee coupler on one end of the trailing car coupled to a short #5 coupler on the lead passenger car and it usually does the trick...a tight radius curve is the culprit..a passenger car truck is longer than a freight car truck and has a hard time making a sharp curve if the body of the car can't swing out wide enough ...the body of the car doesn't swing out wide enough if the couplers are too short ...the longer coupler alliviates this problem because it allows for the car to swing out wider so the longer truck can stay on the rails instead of it being forced off the track when short couplers are used and the passenger car body can't swing out wide enough to make the curve....chuck
