Pulled out the track for the Christmas layout and have it out. I am having a issue where the trains are stopping at the MTH RealTrax operating tracks. I like to run the trains slow to keep the noise down, so at 10mph scale, the trains will pause or stop. At 15mph, the trains will pass. On my outside loop which is long, the diesel will get into clickty clack. When it hits the operating track, it resets. I have turned the tracks both directions and have checked the tabs for connections all around the loop. I even tried moving the lock-ons around to other sides of the operating tracks with no change.
I have not wired these to the AIU yet, but that should not matter.
Any ideas?
