(1) On a schedule determined by the MDT, all railroad companies will be requested to submit information to MDT concerning existing public at-grade signals which need to be upgraded including the following information:
(a) age of the signal circuitry and other signal equipment and availability of parts;

(c) proposed scope of work.
(2) MDT will compile a list of circuitry upgrade projects for all railroads using the following criteria:
(a) available federal funding; and
(b) the recommendation of the railroad companies.
(3) A diagnostic review will be made of each public railroad at-grade crossing considered for circuitry upgrade to determine a scope of work which may include:
(a) improving the road geometric design;
(b) upgrading the existing signal circuitry or other equipment;
(c) installing new signals, gate arms, or cantilevers;
(d) improving sight distance;
(e) removing the signals; and
