I have been having trouble with Con-Cor horn-hook couplers. The couplers are very loose and come apart very easily. Backing the passenger cars is out of the question and there is no guarantee that they will make it once around the layout without letting loose leaving cars standing on the track.
Is there any way that I can tighten up the spring on the coupler so it doesn't release so easily? Is there some way that stability can be built into these long couplers?
Any help would be greatly appreciated. Thanks.......Dave Hick
