Miss. Code Ann. § 77-9-505: Appointment of officers; oath; identification; exercise of powers of arrest and right to bear firearms.

(1) Upon request by the chief police officer of any railroad located wholly or partially within this state, the Commissioner of Public Safety may appoint and commission as a railroad police officer any qualified person named by such chief police officer; provided, however, that the Commissioner of Public Safety may refuse to appoint or may rescind the appointment of anyone. Any such railroad police officer so appointed shall at all times be answerable and responsible to the Commissioner of Public Safety.

(2) A railroad police officer appointed and commissioned as provided in subsection (1) of this section shall, before entering upon his duties as such officer, take the oath of office prescribed by Section 268, Mississippi Constitution of 1890, which shall be endorsed upon his commission. The commission, with the oath endorsed upon it, shall be recorded in the office of the Commissioner of Public Safety.

(3) A railroad police officer appointed and commissioned pursuant to the provisions of Sections 77-9-501 through 77-9-517 shall, while engaged in the performance of his duties, carry on his person a badge identifying him as a police officer of the railroad and an identification card issued by the railroad and countersigned by the Commissioner of Public Safety. When in uniform each such railroad police officer shall wear his badge in plain view.

(4) A railroad policeman may exercise the same powers of arrest and the right to bear firearms that may be exercised by any state, municipal or other police officer in this state, but only with respect to offenses committed against property owned by or in the possession of the railroad or against any person arising out of an offense committed against said railroad on railroad property, or against any employee of the railroad engaged in the performance of his duties. Railroad property for the purposes of Sections 77-9-501 through 77-9-517 shall be construed to mean only property owned by or in possession of the railroad on railroad rights-of-way or switching yards. Any right granted under this subsection in no way relieves the requirements of appropriate affidavit and warrant for arrest from the appropriate jurisdiction and authority pursuant to the laws of this state.

(5) Any person who is trained as a railroad police officer at the Mississippi Law Enforcement Training Academy shall be required to pay at least an amount equal to the per student cost of operation of said academy as tuition.
