QUOTE: Originally posted by Davidvd59 I had the opposite issues, my ac4400 was complete junkand couldn't get it run, make noise wow! I would not EVER buy another one from Athearn. The Sd 40's have been completely reliable and fairly quiet for an Athearn. The Athearn are still running when my Kato's have died.
