I hear you. Mine does that. Mine speeds up and slows down even activates the e-unit sometimes. If I stop it the whistle works fine. Track is clean and rollers. I have a 1952 675 and the 2046W tender the one I cleaned and also a 1952 726 and the 2046W tender and also a 736 with the 736W tender all do the same thing. My MPC and modern Lionel work fine. Nature of the beast?
