Harold,
I bought the 6-11211 in Nov 2011 and had to send it to Lionel for repairs right after I first tried to run it, and then again a few weeks later. Lionel paid for the shipping both ways each time, and kept me informed of the repair and return status via email very diligently. Since then it has been running fine and it is one of my favorite locomotives.
I know it is a hassle to have something that doesn't work right off the bat and then a few weeks later, but Lionel made the repair process about as painless as could be expected. And the locomotive certainly is a fine model.
I now have five Legacy steam locos and seven diesels, and I don't believe I will buy any other type (than Legacy) in the future.
Good luck!
Alex
