Figure 8-2 Minimum Sightlines – Grade Crossings with a Grade Crossing Warning System Drawing not to scale NOTES: 1. SSD and D Stopped are obtained in accordance with section 8.5. 2. For a grade crossing with a grade crossing warning system, subject to the conditions set out in subsection 8.4(b), sightlines of an approaching train within the distance D Stopped must not be obstructed by: (i) trees, brush, other vegetation, or materials stored on the railway right of way; and (ii) the installation of additional equipment housings, tool sheds or any other building or structure.

SECTION 9 – SIGNS AND ROAD MARKINGS Railway Crossing Sign 9.1 Railway Crossing Signs as specified in Figure 9-1 shall be erected at all unrestricted grade crossings. 9.1.1 Number of Tracks supplementary tab Signs as specified in Figure 9-1 shall be erected at all unrestricted grade crossings with more than one track. 9.1.2 Railway Crossing Signs and Number of Tracks supplementary tab Signs shall be located: (a) for grade crossings without grade crossing warning systems, as specified in Figures 9-3 and 9-4; or (b) for grade crossings with grade crossing warning systems, as specified in Figure 18-1. 9.1.3 Retroreflective stripes shall be applied at all unrestricted grade crossings without a grade crossing warning system, to the back of each blade of the Railway Crossing Sign and to the front and back of each sign post, as specified in Figure 9-2. 9.1.4 The Crossing Identification Number shall be applied to the back of one of the Railway Crossing Signs at all unrestricted grade crossings. 9.2 Railway Crossing Sign supporting posts for crossings without a grade crossing warning system shall be of such construction that an 820 kilogram vehicle striking them at speeds from 32 km/h to 100 km/h will not have a change in velocity greater than 4.57 m per second. Railway Crossing Ahead Sign 9.3 (a) Railway Crossing Ahead Signs as specified in the Traffic Control Devices Manual shall be installed on all road approaches for vehicles leading to public grade crossings with an average annual daily traffic (AADT) exceeding 100, including on intersecting roads within 30 m of the nearest rail of the grade crossing. (b) (c) Section 9.3(a) does not apply to a grade crossing in a commercial sector of an urban area if the grade crossing is equipped with a grade crossing warning system which is clearly visible to approaching drivers for the minimum distance specified in Table 19-1, or if approaching vehicles are required to stop within the limit specified in the Traffic Control Devices Manual for the location of a Railway Crossing Ahead Sign. Railway Crossing Ahead Signs shall be located as specified in the Traffic Control Devices Manual. Advisory Speed Tab Sign 9.4 Advisory Speed Tab Signs shall be as specified in the Traffic Control Devices Manual. Stop Ahead Sign 9.4.1 Stop Ahead Signs shall be specified in the Traffic Control Devices Manual. Do Not Stop on Track Sign 9.5 A Do Not Stop on Track Sign as specified in the Traffic Control Devices Manual shall be erected in advance of the grade crossing where it has been determined that queued traffic would otherwise encroach routinely closer than 5 m from the crossing surface. Pavement Markings 9.6 Pavement markings as specified in the Traffic Control Devices Manual shall be applied at unrestricted grade crossings with paved road approaches. Page | 29
