Beware of oncoming trains. No Train Horn sign warns drivers and pedestrian to keep a lookout for an oncoming train. Knowledge is power.
Standard: 01 Either a NO TRAIN HORN (W10-9) sign or a NO TRAIN HORN (W10-9P) plaque shall be installed in each direction at each highway-rail grade crossing where a quiet zone has been established in compliance with 49 CFR Part 222. If a W10-9P plaque is used, it shall supplement and be mounted directly below the Grade Crossing Advance Warning (W10 series) sign.
