The grade crossing between the Rocky Flats Industrial Lead and Colorado Highways 72 and 93 is protected by a stoplight, not a crossing signal. Note the two red lights on the right side of the shot. These red lights is telling the approaching GP40-2s that the light for traffic is still green. As the geeps get closer, they will trip a circuit, turning the light red for traffic.
