PURPOSE: This rule implements the division’s statutory authority to make reasonable rules pertaining to the construction and maintenance of public rail-highway grade crossings and fixed guideway transit systems.

PUBLISHER’S NOTE: The publication of the full text of the material that the adopting agency has incorporated by reference in this rule would be unduly cumbersome or expensive. Therefore, the full text of that material will be made available to any interested person at both the Office of the Secretary of State and the office of the adopting agency, pursuant to section 536.031.4, RSMo. Such material will be provided at the cost established by state law.

1. (1) Every public rail-highway grade crossing on a fixed guideway transit system, whether involving railroad, light rail or street railroad tracks, shall be constructed of materials that will provide a ride quality compatible with that of adjacent roadway surfaces (except that crossings of asphalt material shall have installed headers of equal height to the top of rails installed on both sides of both rails). Rail-highway grade crossings constructed on transit systems shall have, at a minimum, a crossing material comparable to or exceeding the material used in the approaching roadway. Grade crossings constructed of unconsolidated material are prohibited.

   1. (A) The crossing shall be the same width as the approaching roadway including drivable shoulders, plus two feet (2') on each side.
   2. (B) If practicable, the roadway alignment should intersect the transit system 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 rail-highway grade crossing upon a transit system 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 rail-highway 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 highway 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 is incorporated by reference, and is made applicable to fixed guideway transit systems as recommended practices for the construction and reconstruction of rail-highway crossings, if practicable, but with the following changes:

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

lines, as incorporated by reference in this rule, 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 transit system 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 transit system makes a track raise within a rail-highway 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 as 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 transit system shall maintain a pedestrian grade crossing 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 transit system 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 pedestrian grade crossing between the adjacent tracks.
