Lionel’s new car couplers work fine with MTH, Weaver, Atlas and others. Don’t own any Lionel Scale so I’m not sure about that thumbtack design.
BOTTOM LINE - The new cars don’t couple to Lionel’s original PS series era cars.
Question is, what’s Lionel going to do about it? They already lost sales with this issue once before.
Old to new - no good
