I have a nice beginner set of Marx tinplate cars, with 2-wheel trucks, and hook & tab couplers. The couplers are attached with a single rivet underneath the frame.
I would like to add two nice passenger cars. Most of the nicer looking passengers, though, have four wheel trucks, and the couplers are attached to and swivel with the trucks.
Assuming that I convert the passenger couplers to hook & tab, would I be able to mix these passenger cars in a train with the smaller cars with the 2-wheel trucks? Or will the heavier 4-wheel trucks pull the lighter 2-wheel trucks off of the rails (derail) on turns etc.
Thanks for all advice.
