The lights mounted on the ends of the cupolas are marker lights, which designate the rear end of a train. Operating rules required built-in markers like these to be illuminated, and to display red to the rear of the train. <br /> <br />Green was to be displayed toward the rear, rather than red, when the train was clear of a main track at night in territory that was not equipped with automatic block (lineside) signals. <br /> <br />On the UP cabooses equipped with built-in markers, the red light was located at the top of the housing, and the green light below it.
