This bill amends Arkansas law regarding railroads by establishing a limitation on the length of trains operating within the state. It introduces a new subchapter titled "Train Length," which outlines the legislative findings and intent, emphasizing that excessively long trains pose dangers to public safety and disrupt commerce. The bill defines key terms such as "main line," "branch line," "train," and "train length," and sets a maximum train length of 8,500 feet for operations on main and branch lines.

Additionally, the bill imposes civil penalties for violations of the train length limitation, with fines ranging from $500 to $1,000 for each foot over the limit, and a potential one-time penalty of up to $250,000 for gross negligence or repeated violations that result in imminent hazards or injuries. The collected penalties will be deposited into the Arkansas Department of Transportation Fund to support state infrastructure. An emergency clause is included, stating the immediate necessity of the act for public safety and commerce, allowing it to take effect upon approval by the Governor or after the veto period.
