I have done a few Revolution install for Rosenberg RR Museum and I got one that is really giving me a hard time. All my own locos are battery with Revolution and work great. The museum has a garden RR and want to change from DC to Revolution. I did about 6 so far and only small problems. I am now doing a Thomas tank engine and need your help. The test track I am using is nickel silver 250 code. The track at the museum is ss 250 code. Thomas ran fine on DC on the test track. I did the install, he will be running on track power and he was jerky and would lose link. I put him back to DC and cleaned the track with a drywall sander and wiped it down with a wet swiffer. He still ran jerky and lost link. I put him back to DC and he ran great. I tried a new receiver and still got the jerky moving and loss of link. I redid all the power pickup points and tested them and all is fine. I worked on this for a few hours and am lost. If anyone has an clue to what I am missing please let me know. It is now time to go the a garden party at the museum and enjoy some adult drinks. Thank you.
