Although my layout is equipped with O42 track and switches, I recently bought the Sunset Models 3rd Rail Rock Island PEORIA ROCKET train set anyway. I knew upfront that it requires O72 minimum radius track and switches, but bought it for heart-and-soul reasons: I'm a RI fan, I grew up in Peoria, and I rode that train to/from Peoria to Chicago as a teenager. I'll never be able to run it at home (unless I add-on a larger Train Room to the house). so the train is on display only. An expensive indulgence! A photo is attached - the PEORIA ROCKET rests on the third shelf down from the top.
