(b) Regulations.—
If the review conducted under subsection (a) establishes that enhanced railroad car visibility would likely improve safety in a cost-effective manner, the Secretary shall initiate a rulemaking proceeding to prescribe regulations requiring enhanced visibility standards for newly manufactured and remanufactured railroad cars. In such proceeding the Secretary shall consider, at a minimum—
(1) visibility of railroad cars from the perspective of nonrailroad traffic;
(2) whether certain railroad car paint colors should be prohibited or required;
(3) the use of reflective materials;
(4) the visibility of lettering on railroad cars;
(5) the effect of any enhanced visibility measures on the health and safety of train crew members; and
(6) the cost/benefit ratio of any new regulations.
