Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: This amendment updates references to the
				  Manual on Uniform Traffic Control Devices.
(1) Every public rail-highway grade crossing
				on a rail fixed guideway system (RFGS), 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 RFGSs 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.
(A) The crossing shall be the same width as
				the approaching roadway including drivable shoulders, plus two feet (2') on
				each side.
(B) If practicable, the
				roadway alignment should intersect the RFGS 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.
(C) Width of
				roadway at a rail-highway grade crossing upon an RFGS 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, (2009 Edition including Revisions 1 and 2),
				which is incorporated by reference and made a part of this rule as published by
				the Federal Highway Administration, United States Department of Transportation,

.
				This rule does not incorporate any subsequent amendments or additions of this
				manual. These markings are the responsibility of the public highway
				authorities.
(D) Part I
				(subsections 1.4-1.11) of the American Railway Engineering Association's
				Guidelines for the Construction or Reconstruction of Highway-Railway At-Grade
				Crossings, 2013 Edition, which is incorporated by reference, and made a part of
				this rule as published by the American Railway Engineering and Maintenance of
				Way Association, 4501 Forbes Blvd, Suite 130, Lanham-Seabrook, MD 20706. This
				rule does not incorporate any subsequent amendments or additions of these
				guidelines. These guidelines are made applicable to RFGSs as recommended
				practices for the construction and reconstruction of rail-highway crossings, if
				practicable.
