Whilst you have been able to pull them apart, I can guarantee that if ever the battery car derails and the loco keeps moving, you will rip the wires out of the connectors.Cut the hooks off the battery - loco connectors. Don’t worry. they do not come apart on their own durimng normal operations.
Solve the fear of a non functioning TX handpiece. Buy a Spare TX. Mr Polk says they are not expensive.
I have had my battery/sound cars uncouple from the engine numerous times. 90% of the time the connectors disconnect without damage. The other 10% of the time, they do not disconnect, they actually pull the cars along! A real wire coupler!
