In August, all
Alaska Railroad locomotives used in yard and switch service started using
oscillating yellow warning beacons which had been mounted on top of locomotive
cabs in an effort to prevent crossing accidents in the yard areas.
They have proved so successful that a program is underway to equip all
locomotives with the warning device. At present, the beacons are
not used when the locomotives are in road service, and will not be until
such time as all locomotives are so equipped.
