I tried one more time before packing everything back up. The trailing A unit still is totally nonresponsive when trying to program it. The B unit allowed me to "add" it (I get the whistle blast) but then when switched to RUN, it 100% does not accept any Legacy commands, including starting up. It sits there dead.
Dave- again, this isn't you - it's a Lionel QC issue. You are incredibly responsive and I am grateful. I don't expect you to reply to this, but until a few years ago, every locomotive I bought from L was perfect. In the past few years, every single locomotive, Legacy and Vision, I've purchased requires immediate service due to an operating defect. Started with one of my N&W Pocahontas sets with the aluminum passenger cars. The locomotive had jittery non-smooth operation. Sorry to say that even after 2 trips back to L for service it remains that way. Knowing they have an obvious QC issue, is L making any attempt to implement a QC control check (e.g. bump up testing to say 10% instead of 1% or whatever your actual numbers are - if L even does this) so they catch this stuff before the headache is passed along to the customer? I know speed to market matters for revenue recognition, but a delay in RR must be superior to a dwindling customer base as people get turned off and decide to take their business elsewhere? Thanks for listening.
