Okla. Admin. Code § 730:40-1-9
Easements and licenses for public or private utilities and other facilities to be located along or across state-owned railroad properties may be granted by the Department provided their installation and maintenance do not unreasonably interfere with use of the property as a railroad. Easements and licenses may be marketed, managed, and administered by the Department or, in the alternative, such marketing, management, and administration may be performed by the Department's rail service operator pursuant to the provisions of said operator's track lease and operating agreement with the Department; provided, however, the Department shall retain in any such track lease and operating agreement the exclusive right to grant public road and highway crossings.
