I have a relatively new set of the Vision Line 30k gal Ethanol Tank Cars. The coupler on one end keeps coming open for no reason. Bought this set from friend who bought it new from a dealer. Friend never took cars out of their original boxes. I am the first to run these cars. Coupler did not start coming open until I had about an hour of run time on the car. Now it may run 10-15 mins with no problem then all of a sudden coupler will pop open. Running on Fastrack with 072 remote/command control switches.
What to do? Please help! Thanks in advance!
