[quote]QUOTE: <i>Originally posted by rrinker</i> <br /><br />There's probably too much play in the gears. On Athearn and P2K locos you can get small thrust washers from NWSL and others to put on either side of the worm gears to minimize this back and forth play which makes everything run smoother. When the worm gear can move back and forth, you get alternating binding and freeing up, which results in the surging, most often when going downgrade and worse with a train behind pushing. What's happening is the train starts running away from the motor, which pulls the worm gear tight against one side and binds it up slightly. This slows the train until the motor 'catches up' which frees the binding and the whole thing starts over again. <br /> <br /> --Randy <br />[/quote] <br /> <br />Randy, <br /> <br />My hats off to you. That sounds exactly like what is happening! I have not noticed this problem on Athearn or P2K locos, just this Bachmann. Think it would help at all running 2 or more locos in a consist? Perhaps more drag from the second loco would smooth things out? <br /> <br />Thanks again! <br /> <br />Jawbone
