Current through Register Vol. 49, No. 6, March 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.
(2) Unless
otherwise ordered by the division or by agreement, the RFGS shall maintain the
road surface over the length of ties and between tracks where adjacent track
centers are less than fifteen feet (15').
(A)
Unless otherwise ordered by the division, when an RFGS 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.
(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').
(C) Unless otherwise ordered by the division
or by agreement, the RFGS 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 RFGS
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.

1985, amended 1993, 1995.
