DELETE Paragraphs 02 and 03.
INSERT the following paragraphs:
Standard:
01A The automatic gate (see Figure 8C-1) shall consist of a drive mechanism and a fully retroreflectorized red-and white-striped gate arm with lights. When in the down position, the gate arm shall effectively block all approach lanes, the adjacent shoulder, and all sidewalks. Automatic gates shall not be used without railroad flashing-light signals.
Guidance:
01B The gate mechanism should be mounted on the same support as the railroad flashing-light signal.
01C Automatic gates should be perpendicular to the roadway or sidewalk, unless conditions warrant placement at a different angle.
Option:
01D Where conditions require, the gate may be mounted on a separate support located between the railroad flashing-light signal support and the track.
Standard:
01E If the gate is mounted on a separate support located between the railroad flashing-light signal support and the track, the minimum clearances shown in Figures 8C-2, 8C-101, and 8C-102 shall be met.
Standard:
01F In the normal sequence of operation, unless constant warning time detection or other advanced system requires otherwise, the flashing-light signals and the lights on the gate arm (in its normal upright position) shall be activated immediately upon detection of approaching rail traffic. The gate arm shall start its downward motion not less than 3 seconds after the flashing-light signals are activated, shall reach its horizontal position at least 10 seconds before the arrival of the rail traffic, and shall remain in the down position until the rail traffic has cleared the grade crossing.
Guidance:
05B When the rear of the train is approximately 50 feet beyond the crossing, and no other train is approaching, the train should be considered clear of the highway-rail grade crossing.
Standard:
07A Automatic gates, when in the down position, shall not be less than 42 inches or more than 54 inches above the pavement crown or sidewalk. Each roadway gate shall be equipped with at least three red lights with a minimum diameter of 3 inches and visible in both directions along the roadway.
Guidance:
07B The lights should be positioned along the gate at the following distances: the first light should be within one foot of the gate tip, the others should be evenly spaced over the roadway surface, as per Figure 8C-1.
07C If installed, the light on a sidewalk gate should be located approximately over the center of the sidewalk.
Standard:
08A Each sidewalk gate longer than 6 feet shall be equipped with one red light with a minimum diameter of 3 inches and visible in both directions along the sidewalk. The light shall be continuously illuminated when activated.
Guidance:
13A In the down position, the tip of the roadway gate should be within one foot of the left edge of the approach.
