My apologies for not keeping up with the Legacy smoke issue that was discussed a year or so ago. A curious as to what to do here with our Union Pacific Mikado that I purchased new. The smoke went out early on and was sent to and repaired by Lionel quickly and at no charge. It worked fine for a year and a half during occasional use now that we don't have a home layout. The last time I ran it at the club it began the dreaded 3 blinks of death again so it went back up on the shelf until this evening. I have been test running several of our Lionel engines and locomotives this evening on my bench test track. Sure enough, still no smoke and the cab light blinks.
What is the latest information on the best way to rectify this situation please? I was under the impression that they originally had weak smoke units and that the factory repair corrected this giving us a dependable smoke system?
