I've heard that there was talk of designating the second group of FL9's "FL18."

Nope. Never found anything in the records to substantiate that "rumor", including talking to the "old guys" in the Engineering Dept.. I knew Bob Konsbruk very well. He was also responsible for designing and assisted in building the DC substation for the electric locomotive & trolly lines at the Illinois Railway Museum.
