Prohibits railroads from operating trains exceeding 8,500 feet in total length on any main track or branch line

HB 3463 limits the total length of trains operated by railroads on public main tracks or branch lines to 8,500 feet. This directly affects railroad companies operating within the state, requiring them to comply with the new length restriction. The bill grants the Department of Transportation authority to create specific rules for measuring train lengths, granting exemptions for certain routes, and imposing penalties for violations. These rules must follow state administrative procedures and will take effect only after meeting legal requirements.
