This legislation, known as the Railroad Responsibility Act of 2025 , empowers states to enact laws and regulations concerning the duration that railroad carriers may block grade rail crossings. Its primary purpose is to clarify that federal law does not preempt state authority in this specific area, thereby giving states more control over local rail operations. The bill achieves this by amending two sections of title 49, United States Code. Specifically, it adds provisions to sections 10501(c)(3) and 20106(a), explicitly stating that federal law does not preclude a State from adopting requirements to limit the time a train can obstruct a crossing. This aims to address issues related to blocked crossings by allowing states, including the District of Columbia, to set their own limits.
