Did you buy on ebay? If so contact the sender and get a refund!
By the way K-Line had problems with the truck assemblies on the heavy weight cars, the metal used will fall apart and the wheels come out in your hand when you pick one up. K-Line replaced the wheel sets for me free, but I paid for shipping though.
K-Line currently is owned by Lionel, so any new products will have K-Line by Lionel on the box.
