The proposed bill aims to regulate the length of trains operating within the state of Washington, establishing a maximum train length of 8,500 feet unless approved by the utilities and transportation commission. The legislature recognizes the increasing lengths of trains, which pose significant safety risks to the public and the environment, particularly given the state's diverse geographical terrain and the lack of adequate infrastructure to manage such long trains. The bill emphasizes the state's responsibility to ensure safety and security in railroad operations, especially in the event of hazardous material incidents.

To enforce these regulations, the bill outlines penalties for violations, including fines starting at $25,000 for the first offense and escalating for subsequent violations. It also allows for the commission to authorize exceptions for trains exceeding the length limit under specific conditions, such as additional crew members and safety equipment. The commission is tasked with enforcing these provisions and may impose fees to cover the costs of reviewing requests for operating longer trains. The bill includes a severability clause to ensure that if any part is deemed invalid, the rest remains effective.
