The bill establishes new regulations for railroad trains operating in Wyoming, specifically setting a maximum train length of 8,500 feet and requiring compliance with operational standards. It introduces definitions for key terms such as "branch line," "mainline," and "train," and outlines the responsibilities of the director of the department of transportation in enforcing these regulations. The bill also stipulates that trains must not block intersections for more than ten minutes at a time.

In terms of penalties, the bill imposes civil fines on railroad companies that violate the length restrictions, with penalties ranging from $500 to $1,000 per foot over the limit. Additionally, companies that exhibit gross negligence or a pattern of violations that pose a threat to safety may face a one-time fine of up to $250,000. The director is tasked with considering various factors when determining the penalty amount, and any collected fines will be directed to the state highway fund. The act is set to take effect on July 1, 2023.
