Buck, my June '54 OG shows the KC-FLA Spcl arriving at 7:30 am and the eastbound City of StL departing at 7:30 am which would put the two trains in KC at the same time.
A while back a Photo of the Day purported to show "Monon train No. 6, the Chicago - Louisville Tippecanoe stopped at Crawfordsville, IN." Wrong - The Tippecanoe was Monon No's 11 & 12 which ran on the Chicago - Indianapolis line and didn't go through Crawfordsville. The train in the photo was actually the Thoroughbred.
