Well, I finally got around to body-mounting some Kadee #820 couplers to a pair of cars and tested them on the layout. They reduce the space between cars, which I like, and still fits going through my sharpest (6.5’ diameter) curves. The couplers themselves look a lot better to me than the big Bachmann couplers I’ve been using, and they work better too. I really like the more prototypical look of the body mounted couplers.
So as soon as I can get more of them, I’ll convert all my locos and rolling stock. I have several planned modeling projects which have been on hold until I could get this settled.
