@Phil McCaig posted:Thanks, John. I will look at that. Incidentally, I have 2 other Atlas 3-rail engines and they all respond to the throttle exactly in the same manner, sluggish on take-off and can easily run away if you're not watching. I have not tried to set maximum speed with the other 2.
Phil, I have the same problem with an Atlas O GP-9 with EOB. Seems to run OK and then periodically it will just start running at high speed without any input. I've thought it was a problem with the EOB. I wonder if this is related to what you're describing, or if there's something wrong with the EOB.
