Point353, that could be the part. Thanks
Peteski, where a coupler should be at the end of each car , there is nothing. The only thing there is a black piece of plastic. I found one other part that looks like it is part of the setup, but have no idea how it goes together.
I also have the Southern Daylight with the same combined cars and a boxed set of Kinetic couplers as a kit.
I'll look at how they all go together.
Thanks
Rick
