Hi Brad: Mine also came back today. It is still in the box, my three grandchildren are spending the night. They like to open up my Lionel Boxes. We will open it up tomorrow and test the locomotive with the Universal Remote and the App on the iPhone. I went to my local hobby shop yesterday and they were sold out of the Universal Remotes.
Lionel thinks my remote is the issue. The kids are spending two nights because there school is closed this Monday. I will test the loco for several days and report back to this thread on the OGR.
