8.1 Railway Crossing Sign and Number of Tracks Sign
All grade crossings:
8.1.1 A sign providing warning of a grade crossing (Railway Crossing sign) must be as shown in Figure 8-1(a) and must:
- have a retroreflective coating that covers the entire surface of the signs, and
- have a 50 mm border on the front of each blade, with transparent red ink silk-screen processed over sheeting material;
8.1.2 A sign indicating the number of tracks at a grade crossing (Number of Tracks sign) must be as shown in Figure 8-1(b) and must:
- have a retroreflective coating that covers the entire front surface of the sign:
- have a digit and symbol that is transparent red inked silk- screened processed and:
- be installed on the support post of each railway crossing sign as shown in Figure 8-3(c).
Additional requirements for grade crossings without Warning Systems
8.1.3 A 100 mm retroreflective strip must be applied on the back of each blade of the Railway Crossing Sign, for the full length of each blade;
8.1.4 A 50 mm strip of silver white sheeting must be applied on the front and back of the supporting post, extending from no higher than 300 mm above the crown of the adjacent road surface to 70 mm above the centre of the Railway Crossing sign and must be as shown in Figure 8-2.
8.1.5 The railway crossing sign must be located:
- between 0.3 m and 2.0 m from the face of the curb, or the outer edge of the road shoulder or, where there is no curb or shoulder, 2.0 m to 4.5 m from the edge of the travelled way; and
- must not be located closer than 3 m measured to the nearest rail, as shown in Figure 8-3(a) and 8-3(b).
8.1.6 A sidewalk, path or trail with a centreline that is more than 3.6 m (12 ft.) from a Railway Crossing sign supporting post beside a road approach for vehicle traffic must have separate Railway Crossing signs, as shown in Figure 8-3(a).
8.1.7 The supporting post, on which is installed the Railway Crossing sign and the Number of Tracks sign, must:
- Unless the Railway Crossing sign is installed on the mast of a warning system, the supporting posts must be of such construction that a 820 kg vehicle striking it at speeds 32 km/h or more, will not have a change in velocity greater than 4.57 m per second.
8.1.8 Retroreflective material referred to in 8.1.1 to 8.1.4 must meet the specifications for Type IV material, white sheeting, as specified in sections 4.2.4 and 6.1.4 of ASTM D4956 (cited in Part A) when tested in accordance with the Test Methods for Type IV material specified in sections 7 and 9 of that Standard.
8.1.9 The retroreflection coefficient of the retroreflective material referred to in 8.1.8 is to be maintained above 50 per cent of the value specified for Type IV material specified in article 6.1.4 of ASTM D4956 (cited in Part A).

8.2 Railway Crossing Ahead Sign and Advisory Speed Tab Sign
8.2.1 A sign providing advanced warning of a grade crossing (Railway Crossing Ahead sign) and a sign specifying a recommended speed (Advisory Speed Tab sign) must be as shown in articles A3.4.2 and A3.2.5 in the Manual of Uniform Traffic Control Devices for Canada (cited in Part A) and must meet the applicable standards set out in article A1.6 of that Manual, as the case may be.
8.3 Stop Ahead Sign
8.3.1 A Stop Ahead sign must be as shown in article A3.6.1 of the Manual of Uniform Traffic Control Devices for Canada (cited in Part A) and must meet the applicable standards set out in article A1.6 of that Manual.
8.4 Stop Sign
8.4.1 A Stop sign must be as shown in article A2.2.1 of the Manual of Uniform Traffic Control Devices for Canada (cited in Part A) and must meet the applicable standards set out in article A1.6 of that Manual. Where required by law, the word “Arrêt” will replace the word “Stop”, or may be added to the Stop Sign.
8.4.2 When a Stop sign is installed on the same post as a Railway Crossing sign, it must be installed as shown in Figure 8-4.

8.5 Emergency Notification Sign
8.5.1 An Emergency Notification sign that provides information on the location of the grade crossing and the railway company’s emergency telephone number, must be installed
- parallel to the road, or
- on each side of the grade crossing, facing traffic approaching the grade crossing.
8.5.2 the emergency notification sign must be clearly legible
