HELP! I have been looking for some Atlas trainman AAR 70 ton open hoppers 3 pack and I have only found 2 and would like to find 5 more to at least have a 20 plus car train. They all say out of stock and to be discontinued. So what does a late bloomer do have them painted up. Is there any hope out there to get lucky and find them.HELP! would be highly appreciated. Thanks for your time Blane
