Have an Atlas Trainman RS3 equipped and running on 18V TMCC that Sputters/stalls on certain areas of my layout using Atlas track.
The locomotive has less than one hour running time I have cleaned rails-tops and insides, cleaned rollers, cleaned whatever I can think of (with alcohol). Sometimes it helps, sometimes it doesn't at the same position. I cant tell whether I'm losing hot or ground. All you have to do is touch the loco lightly and it will light up and sputter some more until it is happy and then runs on with no problem.
My Lionel and MTH locomotives cruise over the entire layout with no problem. Have not run an Atlas Master or 3rd rail locomotive yet. (my 2-10-4 is on the way though).
Not a big fan of the Trainman pickup system vs all others, unless something changes no more Trainmans for me..
Any ideas, suggestions?
