25 or 30 years ago I watched a video of someone who had found an undocumented feature of a Lionel steamer with TMCC. After a sequence of button pushes, the engine would say "I think I can, I think I can ..." I think the video featured the guy's layout and this was just a part of his show. I think it might have been a Lionel Collectors Club 773 Hudson, but I don't remember if all of those engines had it, or if just a random selection. I had volumes 1-4 of O-Gauge Railroading the Video and 11 Toy Train Review videos, so it must have been one of those. Can anyone tell me the button sequence for me to try with my 773? Or does anyone know the specific video?
Thanks!
