Railroad Crossing Stop Signs If you approach a railroad crossing at which a stop sign is posted, you must come to a complete stop and proceed across the tracks only after looking both ways to make sure a train is not approaching. Never assume the track is not used or a train is not approaching. Safety Guidelines for Railroad Crossings: Obey the Warning Signs Look both ways and LISTEN, because you may have to stop. Expect a train on any track at anytime. Don’t trust a schedule because trains can cross at anytime of the day or night. Due to the size of trains, the actual speed of a train can be very deceiving.
