I wonder if some operators have had it where it has stopped working only briefly and then gone right back on. I'm guessing this is really hit or miss to discover, wonder if Lionel got a few and had nothing show up on the radar. I seem to remember Dave talking about something(maybe the Mogul or some other engine) that he couldn't replicate the issue that was described on the topic. If I recall, it was both frustrating for Dave and the poster on that problem.
I'm wondering the same thing. There also might be some of these sitting in a box that people haven't tested yet, but I suspect they should dig them out and try them. 
It's hard to truly blame Lionel service, since it worked perfectly on my layout, I suspect they had the same experience. I blame the person who decided it was a good idea to stick the TMCC antenna next to an EMI generating power supply.
@zhubl posted:That is a crazy find. Just out of curiosity how new was this diner? I am pretty sure my up excursion diner doesn’t have a switching power supply and I definitely not remember the antenna being on the other side of light PCB.
This was a pretty new diner, Lionel 2127090. As for the switching supply, if you have the LED lighting that has the supercap that holds it up for a minute or so without power, you probably also have the switching power supply.
