(a) Review of Rules.—
(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—
visibility of railroad cars from the perspective of nonrailroad traffic;
whether certain railroad car paint colors should be prohibited or required;
the visibility of lettering on railroad cars;
the effect of any enhanced visibility measures on the health and safety of train crew members; and
In prescribing regulations under subsection (b), the Secretary may exclude from any specific visibility requirement any category of trains or railroad operations if the Secretary determines that such an exclusion is in the public interest and is consistent with railroad safety.
