(1) The devices listed in the MUTCD and the devices listed in Sections (2), (3), (4), (5), (6), and (7) of this rule are “standard protective devices.” (2) Passive Devices: (a) Railroad STOP Sign Figure 1 is a fixed rectangular sign that shall bear the word “STOP” in white reflective letters on red reflective material. (b) Stop Clearance Line is a stop line as defined in Section 1A.13 of the MUTCD, which is 24 inches wide. (c) “Illumination” (Figure 4) is a system of luminaires arranged in a unique pattern to provide direct lighting on the side of railroad equipment occupying a grade crossing during hours of darkness. (3) Active Devices at Grade Crossings: (a) Flashing-Light Signal is as set forth in Section 8C.02 of the MUTCD, which has an audible warning device. For additional specifications for Flashing-light signals, refer to subsections (e) and (f) of this section. (b) Cantilevered Flashing-Light Signal is as set forth in Section 8C.02 of the MUTCD, which has an audible warning device. For additional specifications on cantilevered Flashing-light signals, refer to subsections (e) and (f) of this section. (c) Pedestrian Flashing-Light Signal is as set forth in Section 8D.06 of the MUTCD. For additional specifications on Pedestrian Flashing-light signals, refer to subsections (e) and (f) of this section. (d) Automatic Gate is as set forth in Section 8C.04 of the MUTCD. (e) Light units on Flashing-light signals, Cantilevered Flashing-light signals, and Pedestrian Flashing-light signals shall be aligned so that insofar as it is practical to do so, at least one full 12-inch diameter red light shall be visible when viewed from any point on the roadway within the safe stopping distance. (f) Unless otherwise specified, 12-inch diameter roundels (lenses) on Flashing-light signals, Cantilevered Flashing-light signals, and Pedestrian Flashing-light signals, if incandescent bulbs are used, shall be as follows: (A) Front light units: roundel rated with a 30-degree horizontal and 15-degree downward spread. (B) Back light units: roundel rated with a 70-degree horizontal spread. (C) Cantilevered front and back light units: roundel rated with a 20-degree horizontal and 32-degree downward spread. (4) Auxiliary Devices. The Department may authorize the installation of auxiliary signs and signals at a crossing. Such devices shall be installed so as not to obscure other crossing signs or signals at the crossing. (5) Advance Warning Devices: (a) Train-Activated Advance Warning Device (Figure 3) is a signal that shall alternately flash two yellow lights along the highway in advance of a crossing, to provide warning of an approaching train. (b) Skewed Angle Bicycle Warning sign is the skewed crossing (W10-12) sign in Section 8B.25 of the MUTCD. If used at pathway-rail grade crossings, the sign size depicted in Table 9B-1 of the MUTCD for a shared-use path shall be used. (6) Guardrail is as depicted in Oregon Standard Drawing No. RD445. (7) Curb is a standard curb as depicted in Oregon Standard Drawing No. RD700. [ED. NOTE: Figures referenced are available from the agency.]
