K-Line made two versions: Cedar Rapids (18") and Adler Creek (21"). The "Friends of 261" out of Minneapolis have done a superb restoration of Cedar Rapids and the Super Dome. I have ridden it twice. Also known by some as "The Frank Sinatra Car", it was the first class car for the Olympian Hiawatha. Our family couldn't afford tickets to travel in that car, so it wasn't until 60 years later that I could!!!
