PURPOSE: This rule implements the provisions of section 389.610, RSMo, as enacted in Senate Bill No. 676, General Assembly, Second Regular Session, 1988, which authorizes the division to make reasonable rules pertaining to the construction and maintenance of all public grade crossings.

Editor’s Note: The secretary of state has determined that the publication of this rule in its entirety would be unduly cumbersome or expensive. The entire text of the material referenced has been filed with the secretary of state. This material may be found at the Office of the Secretary of State or at the headquarters of the agency and is available to any interested person at a cost established by state law. (1) Every crossing shall be constructed of materials that will provide a ride quality compatible with that of adjacent roadway surfaces (except that crossings of unconsolidated or asphalt material shall have installed headers of equal height to the top of rails installed on both sides of both rails).

1. (A) The crossing on paved roads shall be the same width as the approaching roadway including drivable shoulders plus two feet (2') on each side. On gravel roads, the crossing shall be the same width as the traveled way, which shall be deemed to be the width of the crossing on April 27, 1989 but not less than sixteen feet (16').
2. (B) If practicable, the roadway alignment should intersect the railroad track at or nearly at right angles. The roadway surface shall be in the same plane as the top of rails for a distance of two feet (2') outside of rails for either multiple or single track crossings. The top of the rail plane shall be connected with the grade line of the roadway each way by vertical curves of the length required to provide riding conditions and sight distances normally applied to the roadway. It is desirable that the roadway surface be not more than three inches (3") higher nor six inches (6") lower than the top of the nearest rail at a point thirty feet (30') from the rail, measured at a right angle, unless track superelevation dictates otherwise. Where crossings involve two (2) or more tracks, the top of rails for all tracks shall be brought to the same plane where practicable.
3. (C) Width of roadway at a highway-railway grade crossing should correspond to that of the adjoining highway and have the same number and width of traffic lanes as the adjoining highway without extra lanes and with center turn lanes at the crossing delineated. At all paved approaches to the highway-railway grade crossing, the highway traffic lanes in the vicinity of the crossing should be distinctly marked in accordance with the recommendations of the Manual on Uniform Traffic Control Devices for Streets and Highways. These markings are the responsibility of the public authorities.

4. (D) Part I (subsections 1.4—1.11) of the American Railway Engineering Association’s Guidelines for the Construction or Reconstruction of Highway-Railway Crossings are adopted by reference as recommended practices for construction and reconstruction of crossings, if practicable, but with the following changes:

   1. 1. Paragraph 1.9.8, line 1, of the guide-

lines, as adopted, is amended by striking out the numeral “115,” and inserting the numeral “112” in lieu of 115.

1. (2) Unless otherwise ordered by the division or by agreement, the railroad corporation shall maintain the road surface over the length of ties and between tracks where adjacent track centers are less than fifteen feet (15').

   1. (A) Unless otherwise ordered by the division, when a railroad corporation makes a track raise within a grade crossing, the runoff along the roadway shall be maintained at not more than two inches (2") in the first ten feet (10') outside the end of ties, not more than six inches (6") in the next ten feet (10') and the remaining run-off shall be brought to the same elevation of the existing grade within an additional ten feet (10') along the roadway.
   2. (B) When a highway authority raises the road surface along an approach to a crossing, the run-off along the roadway shall be not more than two inches (2") in the first ten feet (10') outside the end of ties with the remainder in the next ten feet (10').
   3. (C) Unless otherwise ordered by the division or by agreement, the railroad shall maintain a crosswalk of equal width as the approaching sidewalk over the length of ties and between tracks where adjacent track centers are less than fifteen feet (15') apart. The railroad shall use a durable contrasting material between the ends of ties when the approaching sidewalk is constructed of a hard surface material. Any durable material compatible with the material used on the sidewalk may be used on the crosswalk between the adjacent tracks.
