I just purchased my one and only ten wheeler from a friend, and I love it.
Mine is the Lionel TMCC NY Central Lines (B&A Div.) 4-6-0 steamer, which I believe was in the 2002 catalogue. What is critical for me is that it runs on 031 curves, unlike the more recent Legacy model that required 054 curves.
It has great smoke, sounds and detail, and runs and pulls beautifully. Arnold
