Ok, a F40ph P/S 2, Came to us from the forum, all is good. I thought, placed on track and no response with the remote. My ? was why no activity, on the Dcs system, as small lights would come on and nothing after that. Now, I ran engine conventional, all sounds, smokes, like a barbeque hickory wood smoker, horn shakes the room, pulls 16 hoppers around my 8 X 8. Did this about 3 months. This past week, I'm thinking, Maybe............. well I place on my fixed 2 tiu track, and get out the remote. I wonder, power track, and Voila,
