While driving yesterday I was stopped at a crossing west of Monticello, IN on a lightly used track. The train whistle was consistent with a high speed train which is odd because this old Monon track is usually slow grain trains. Much to my surprise I saw a four axle geep pulling a passenger car called the Columbus and a track geometry car moving at a quick clip. There was a guy watching the tracks go by in the rear window. Not at all what I was expecting. Wish I had a camera on the ready! Anyone have any history in these two cars?
