these get hard over time. is there any way keep them flexible, or bring back there flexibility

Are we talking the rubber ones or the cloth?

FWIW, I prefer the O scale rubber ones with the metal strike plates and inner tabs to keep the diaphragms between the two cars aligned. Although the tabs get in the way on tighter diameter curves,

Picture?

I've had this question for a while, and this seems like a good thread to ask it.  What exactly is a 'heavyweight' passenger car?  Is it one made out aluminum?  Does it have to be a certain length?

now that there are some flexible resins, I may look into making 3D printed gangway connections.

I stopped because the standard resins were too hard and inflexible.

The heavyweights were constructed with older materials, lots of wood and riveted steel.  They were heavy and used 6-wheel trucks, hence the name.  The modern passenger cars went to much lighter construction for efficiency.
