Current through June 17, 2024
002.01 DIAGNOSTIC TEAM REVIEW
A Diagnostic Team Review will be completed to determine the final
	 design for the approach roadway, grade crossing and type of traffic control
	 devices including active warning devices. The determination of the Diagnostic
	 Team Review shall be final. The following minimum design standards shall apply
	 to new public highway-rail grade crossings.
002.01A APPROACH ROADWAY/CROSSING SURFACING.
  The approach roadway and crossing surfacing shall be constructed to conform to
  the design standards for new construction applicable to the State functional
  classification of the public roadway, or the following standards, whichever are
  more stringent.
002.01B CROSSING
  SURFACING - WIDTH. The crossing surfacing, from end of tie to end of tie, shall
  extend at least two feet beyond the outside edge of the highway surfacing, but
  in no case shall the crossing width be less than 20 feet.
002.01C CROSSING SURFACING - HEIGHT. The
  surface elevation of the roadway and the top of the railroad tracks shall be
  within 1/2 inch of each other, measured between the top of the railroad track
  and the plane of the approach roadway 2 feet outside the near rail.
002.01D CROSSING SURFACING - BETWEEN RAILS.
  The highway-rail grade crossing must be solidly constructed with no openings
  except as necessary for operation of the railroad track. The crossing surfacing
  shall be made of durable material. Durable material shall mean timber, asphalt,
  concrete or equivalent.
002.01D1 The
  following types of crossing surface systems between rails shall be the minimum
  required at all public highway-rail crossings:
Exposure Factor
Surfacing
0-3000
Timber or Asphalt
3000 & Above
Concrete or Equivalent
002.01E ROADWAY VERTICAL ALIGNMENT. The
  crossing surface shall be on the same plane as the top of the rails for a
  distance of 2 feet outside the rails. The surface of the approach roadway shall
  not be more than 3 inches higher or lower than the top of the nearest rail at a
  point 30 feet from such rail. Vertical curves shall be used to traverse from
  the roadway grade to a level plane at the elevation of the rails.
002.01F TRAFFIC CONTROL DEVICES. Traffic
  control devices must be placed as shown in the MUTCD, and such devices shall be
  of a type, size, and construction that conform to MUTCD requirements. Active
  warning devices shall be considered the minimum required devices necessary for
  any location with a Class 3 or greater track. Active warning devices shall be
  considered the minimum required devices necessary for any location with a Class
  2 or lower track when any one of the following conditions is present:
002.01F1 Anticipated exposure factor of 3000
  or above.
002.01F2 Train count of 2
  or more trains a day.
002.01F3
  Sight or visibility triangle not meeting the requirements of Section
  002.01G.
002.01F4 Multiple tracks.
002.01F5 Approach angle of roadway and tracks
  greater than 15 degrees.
002.01G SIGHT DISTANCE. Sight distance for
  new public highway-rail grade crossings shall be determined according to the
  following table. The sight triangle must be clear of all permanent obstructions
  such as buildings, structures or topography. The Diagnostic Team shall evaluate
  obstructions such as haystacks, crops or other vegetation, continual or
  seasonal.

002.01H HORIZONTAL ALIGNMENT. Public
  highway-rail crossings shall, whenever practicable, be constructed so that the
  highway intersects the tracks at a right angle (90 degrees) with no public
  highway intersections or driveways on railroad property or within 100 feet of
  the outside rail. Railroad access drives and maintenance of way service roads
  are excluded from this requirement.
