Posted by DaveO on 12/30/2019, 8:28 am, in reply to "Flashing Blue Lights in the Rail Yard" Blue lights, blue flags, blue signs are used to protect workers maintaining equipment. You don't move equipment protected by the blue light/flag/sign. They are to be removed only by the person that placed it or a member of the same craft. After verifying that everyone is safely away of course.
