I recently purchased 2 Proto-2000 PA1 locomotives and they aren't running very well. The problem is they don't run smoothly; they surge and jerk down the track. It's most noticeable when going down a grade and at medium speeds. I've tried a number of things suggested by friends and online forums - making sure there is no play in the worm gears, cleaning off old grease and re-lubricating the mechanism and even trying a DCC decoder with back-EMF however nothing seems to work. Has anyone out there had this problem or something similar? A friend of mine is having the same problem with his PAs, so I don't think this problem is limited just to me!
