Railroads; prohibiting operation of trains exceeding a certain length. Effective date.

SB 353 prohibits railroad companies in Oklahoma from operating trains longer than 8,500 feet or exceeding the length of the shortest siding/track on any main or branch line, and limits how long trains can block intersections (no more than 10 minutes). It directly affects railroads operating in Oklahoma, particularly those using main lines or branch lines with specific track configurations. Violations incur fines starting at $500 per foot of excess length, with higher penalties up to $250,000 for repeated or grossly negligent violations causing harm. The Oklahoma Transportation Commission enforces these rules, and collected fines fund the state transportation budget.
