I have a question regarding the use of class lights on GP 7's and 9's on the "Q" in general during the 1950's and early 1960's. I would also like to know if the practice was followed on the C&I. As I recall a "green class light" (or flag) would indicate that an unscheduled extra of the same train would follow. A "white class light" (or flag) would indicate that the train was the extra. So for trains following the standard schedule would there be no class light illuminated ? By the mid 1950's and into the 60's would the "Q" have used class lights or flags along the C&I or did they follow another practice by then?
