GRADE CROSSING WARNING SYSTEMS SECTION 11 – GRADE CROSSING WARNING SYSTEMS Vehicles 11.1 Unrestricted grade crossings for vehicular use shall have a grade crossing warning system if: (a) the forecast cross-product is 1,000 or more and the maximum railway operating speed exceeds 15 mph; or (b) the grade crossing does not include a sidewalk and the maximum railway operating speed exceeds 80 mph; or (c) the grade crossing includes a sidewalk and the maximum railway operating speed exceeds 60 mph; or (d) there are two or more tracks and trains may be passing one another and the maximum railway operating speed exceeds 15 mph; or (e) the sightlines or alternative measures specified in section 8.3 are not provided, including where trains, engines, railway cars, or other railway equipment, standing or stored, may obscure driver or pedestrian sightlines of a train approaching the grade crossing; or (f) the maximum railway operating speed exceeds 15 mph, and there is a Stop sign, or traffic signals controlling vehicular traffic on that part of the road leading away from the grade crossing where the distance between the front of a vehicle in the first stopped position at the Stop sign or traffic signals and a rail in the grade crossing surface is: (i) less than 30 m for a Stop Sign (refer to Figure 11-1 (a)); or (ii) 30 m or more for a Stop Sign, unless a traffic study indicates that queued traffic will not encroach within 2.4 m of the rail nearest the road intersection (refer to Figure 11- 1, (a)); or (iii) less than 60 m for traffic signals, (refer to Figure 11-1 (b)); or (iv) 60 m or more for traffic signals, unless a traffic study indicates that queued traffic will not encroach within 2.4 m of the rail nearest the road intersection (refer to Figure 11- 1, (b)); or (g) the maximum railway operating speed exceeds 15 mph and there is any situation causing vehicles routinely to stop and to queue closer than 2.4 m to the nearest rail in the crossing, for example, as a result of a Yield sign, a roundabout, a pedestrian crosswalk, a bikeway, or a stopped vehicle waiting to make a left turn. Alternatively, if the grade crossing is located where trains stop before entering the grade crossing, train movements over the grade crossing may be manually protected, or traffic signals may be installed in lieu of a grade crossing warning system. The normal display of such traffic signals shall be a green light for road traffic, while trains will be required to stop until given an indication that they are to proceed. Pedestrian or Cyclist Paths 11.2 Unrestricted grade crossings for pedestrian or cyclist use only, shall have a grade crossing warning system where: (a) (b) the maximum railway operating speed exceeds 60 mph; or the maximum railway operating speed exceeds 15 mph and there are two or more tracks at the grade crossing where trains may be passing one another.

Figure 11-1 Proximity of <strong>Grade</strong> Crossing Warning Systems to Stop Signs and Traffic Signals (a) Near Stop Signs NOTES: Where the maximum train operating speed exceeds 15 mph: 1. if D is less than 30 m, a grade crossing warning system including gates is required; 2. if D is 30 m or greater, a grade crossing warning system including gates is required if it is determined that traffic may routinely queue within 2.4 m of the rail nearest the road intersection. (b) Near Traffic Signals Drawings Not to Scale NOTES: For grade crossings or road intersections nearby an existing grade crossing, where the maximum train operating speed exceeds 15 mph: 1. if D is less than 60 m, a grade crossing warning system including gates is required; 2. if D is 60 m or greater, a grade crossing warning system including gates is required if it is determined that traffic may routinely queue within 2.4 m of the rail nearest the road intersection Page | 37
