I would like to change all of my couplers to the new (smaller) dummy knuckle couplers. I looked at the couplers in the accessories (product code 4232) but there was no way to tell if these were the new (small) couplers or the original (larger size) ones. Also, do the springs come with these? The picture of the package was not very helpful.
if you are planning a complete change-over, I would recommend going to MicroTrains couplers, they are far more reliable and look better.....
