All railroads are common carriers affected with a public interest and subject to regulation as prescribed by this chapter and other applicable provisions of law. The commission, to the extent not inconsistent with federal law, shall regulate railroads to ensure that all rates, facilities, and services are just and reasonable, and are not unduly discriminatory, unduly or unreasonably prejudicial, nor unduly or unreasonably preferential.
