Reply to "what is it with MTH a-b-a's trailing truck "bouncing"?"

Jack MoreyOGR Forum Member

I have experienced that with all my Proto 2 A-B-A’s My Proto 3’s don’t seem to do it. It’s jumping because it is running at a different speed than the other trucks. The traction tire is grabbing the rail. Your explanation in your original post, I believe is the reason why. I just figured the trailing truck was getting erroneous information from the cruise control of the lead unit when it was being pushed from behind, as in going downhill. A DCS expert may be able to fully explain the issue, but I don’t believe the trailing unit has a tach reader, but gets all it’s information from the lead unit through the tether. A-B-A’s without the tether, as in later Proto 3 models, don’t have the issue. I could have this all wrong, but this has been my (non-technical) experience.
