Rusty, what were the four fantasy schemes for American Flyer Challenger? On the NASG website I looked up the models offered by Lionel (Clinchfield, Denver and Rio Grande Western, Great Northern, Northern Pacific, Western Pacific, and Spokane/Portland & Seattle) and checked the history of the Challenger 4-6-6-4 class, and it appears that all of these railroads did own Challengers. Many did not like them and traded them off to other railroads as soon as they could, but they did run them. Or did Lionel take some liberties with the sizes of driving wheels and graphics from real life? I'm curious because I thought Lionel did a good job with these after recovering from the Big Boy.
