Current through June 17, 2024
003.01 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 reconstructed public highway-rail grade crossings.
003.01A 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.
003.01B 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.
003.01C 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.
003.01D 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 and the elevation of the surfacing shall be
  within 1/2 inch of the top of the rail. Durable materials shall mean timber,
  asphalt, concrete or equivalent.
003.01D1 The
  following types of crossing surface systems between rails shall be the minimum
  required:
Exposure Factor
Surfacing
0-3000
Timber or Asphalt
3000 & Above
Concrete or Equivalent
003.01E 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 the rail. Vertical curves shall be used to traverse from the
  roadway grade to a level plane at the elevation of the rails.
003.01F 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
  locations with an exposure factor of 3,000 or above, a minimum of 100 vehicles
  per day, and when any one of the following conditions is present:
003.01F1 Clearing sight distance not meeting
  the requirements of Section 003.01G.
003.01F2 Multiple tracks.
003.01F3 Approach angle of roadway and tracks
  varying from 90 degrees by 15 degrees or more.
003.01G CLEARING SIGHT DISTANCE. Clearing
  sight distance is defined as the distance a stopped driver must be able to see
  down the tracks in both directions from a distance of 15 feet from the near
  rail in order to move his or her vehicle safely across the tracks to a point 15
  feet past the far rail, prior to arrival of a train. The required clearing
  sight distance along both directions of the track, from the stopped position of
  the vehicle, is dependent upon the maximum train speed and the acceleration
  characteristics of the "Design Vehicle." The table values are for a level, 90
  degree crossing of a single track. The Diagnostic Team shall evaluate
  circumstances not meeting these requirements and adjust the table accordingly.

003.01H HORIZONTAL ALIGNMENT. Public
  highway-rail crossings shall 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 o utside rail.
  Railroad access drives and maintenance of way service roads are excluded from
  this requirement.
