Railroads; defining terms; limiting length of certain trains; emergency.

HB 2830 limits all trains operating on Oklahoma's defined "main lines" (Class 1 railroads with scheduled service) and "branch lines" (secondary lines branching from main lines) to a maximum length of 8,500 feet. The bill directly affects railroads operating within Oklahoma that use these specific types of rail lines. It defines key terms for clarity and prohibits longer trains to enhance safety, with an emergency declaration ensuring immediate implementation upon approval. The law creates a concrete, measurable restriction on train length without specifying enforcement details.
