Have you been watching all these Kadee conversions for the 3-rail scale equipment? Now you can keep those tight curves and have scale couplers.
Thanks to Ricky Bivins' interest in this and months in the making, we present a truck-mounted coupler box; this is a Lionel rotating roller bearing truck. I also want to thank Ron_H and Norton for their input, as well, here on the forum!
These are the ideal way to convert to Kadee-type couplers (#740-series) for O scale 3-rail trains, by adapting the coupler to the truck. This provides a prototypical buffering action, and attaches with a single screw, with no coupler box cover needed. The spring goes in front of the screw lug, and the only way to convert to scale couplers and keep those tight radius curves.
Guaranteed no mark up.
I want as many people to convert to Kadee as possible, as the more we do, the more they'll make.
Lets do this!
