Certain clearance requirements definitions for certain carriers clarification provision

SF 596 amends Minnesota Statutes section 219.455 to clarify specific definitions related to railroad clearance requirements. It adds formal definitions for terms like "depot company," "terminal," "yard," and "yard track" within existing railroad regulations. This bill directly affects how Minnesota's railroad statutes are interpreted, particularly regarding infrastructure and operations. It does not create new requirements or impact specific carriers; it only refines the legal definitions used in current law. The bill is a technical clarification, not a substantive policy change.
