QUOTE: Originally posted by cacole Maybe I just got lucky -- I have had none of the problems with my Lionel Challenger that other people have reported. It pulls like crazy, runs very smoothly, and has no rocking motion. My only critique had to do with the lousy whistle sound. It took a lot of tweaking as per the recommended DCC CV settings posted at Tony's Train Exchange's Web site to get the whistle fine-tuned, but it still sounds harsh and raspy. I did not use any cotton in the speaker as recommended there, though, and am not going to risk damaging the speaker by doing that. Overall, I am very satisfied with my Lionel Challenger. After reading a comment that the new Athearn Challenger uses an MRC sound system instead of QSI, and that it doesn't sound very good at all, I'm glad I have the Lionel.
