1. (1) The Division of Motor Carrier and Railroad Safety incorporates by reference in this rule Part VIII of Federal Highway Administration, U.S. Dept. of Transportation, Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) (1988 edition), and makes it applicable to fixed guideway transit systems. Part VIII, entitled “Traffic Control Systems for Railroad-Highway Grade Crossings,” establishes standards for the design, installation and operation of railhighway grade crossing warning devices. The division recommends that the standards in Part VIII be applied in the installation of all grade crossing warning systems on fixed guideway transit systems in Missouri, unless 4 CSR 265-9

otherwise provided by rule or order of the division.

1. (2) The Division of Motor Carrier and Railroad Safety incorporates by reference in this rule Part VIII of the Manual on Uniform Traffic Control Devices (MUTCD) (1988 Edition), with the following changes:

   1. (A) Except as otherwise ordered by the division, the minimum allowable warning device shall conform to the specifications of section 8C-2, flashing light signal, at pages 8C-1 to 8C-2 of MUTCD, used in combination with section 8C-4, automatic gates, at pages 8C-3 to 8C-5 of MUTCD;

   2. (B) The following section is added immediately after section 8B-9 at page 8B-7 of MUTCD:

      8B-10 Crossing Inventory Number

The proper DOT/AAR crossing inventory number shall be displayed in a conspicuous location at each grade crossing.

1. (C) The sixth paragraph as contained in section 8C-7 at page 8C-10 of MUTCD is deleted. This paragraph provides as follows:

Two sizes of lenses, 8-inch diameter and 12- inch diameter, are available for flashing light signal units. The larger lens provides somewhat better visibility. In choosing between the sizes of lenses, consideration should be given to the principles stated in section 4B-A for choosing between the 8-inch and 12-inch lenses for use in highway intersection traffic control signals.

1. (D) The following section is added immediately after section 8C-7 at page 8C-9 of MUTCD:

   8C-8 Lens Dimensions

Only 12-inch diameter lenses shall be used on flashing light signal units, unless the division grants a specific exemption.
