SF No 596 is a legislative bill that seeks to clarify and update the definitions related to railroad operations and facilities in Minnesota. The bill proposes amendments to existing statutes to clearly define terms such as "depot company," "passenger service," "railway company," "terminal," and "yard." These definitions are relevant for understanding the operations involving the construction and management of passenger stations, the provision of intercity and commuter rail services, and other railroad-related activities including the loading, unloading, transferring, and servicing of trains. This bill ensures clarity in the language used in legislative statutes, which can help in the efficient management and regulation of railroad operations in Minnesota.
