During the days of Timetable & Train Order operation, classification lights on locomotives were an important safety feature. Able to be illuminated in white, green, or red, class lights were used to indicate whether a locomotive was pulling an unscheduled extra train, had a second section of the same train following it, or was on the tail end of a train, respectively. When computers and electronic communication methods came into use during the 1960s and 70s, TT&TO operation was phased out, and classification lights were no longer needed. Many new locomotives were built without them, some older ones had their class lights removed, and today, it's rare to find a locomotive with class lights still intact. One survivor is Hartwell Railroad number 1973, a former CSX, ex-Conrail, nee Penn Central GP38, seen here at Lavonia, Georgia.
