Hi Larry, <br />The symptoms you describe do not sound normal. If the engines run well with a different power pack, and fail to run well with the new ones you bought, I believe the problem would be in the power pack. The momentum feature on the MRC packs works by slowly increasing the voltage up to the level selected by the knob. This allows the train to appear that it is loaded and is increasing in speed gradually. How long did you wait for the trains to reach full speed? I have an MRC "sound & power 7000" that I obtained ten or eleven years ago, and it still works like new. With momentum turned on, it takes a couple minutes to reach the selected speed. If yours is taking more than about two minutes and the trains are still not functioning, I would suspect a problem. If you have a multimeter, you can read the track voltage at the supply terminals to see what it's doing. If the voltage is increasing as it should, then the problem would be in the locomotive or the track itself. Try a different locomotive (if possible) to see if that may be the problem. Otherwise, try reading your track voltage at various locations around your layout to see if you have a bad rail joiner or other form of electrical connection. I hope these ideas at least help you to determine the source of your problem, so you can focus on where the problem lies. If you still need help after this, just ask! <br />-Joe
