49 U.S.C. § 28101: Rail police officers

employees, passengers, or patrons of the rail carrier; property, equipment, and facilities owned, leased, operated, or maintained by the rail carrier; property moving in interstate or foreign commerce in the possession of the rail carrier; and personnel, equipment, and material moving by rail that are vital to the national defense. A railroad police officer directly employed by or contracted by a railroad carrier and certified or commissioned as a police officer under the laws of a State may be temporarily assigned to assist a second railroad carrier in carrying out law enforcement duties upon the request of the second railroad carrier, at which time the police officer shall be considered to be an employee or agent, as applicable, of the second railroad carrier and shall have authority to enforce the laws of any jurisdiction in which the second railroad carrier owns property to the same extent as provided in subsection (a). If a railroad police officer directly employed by or contracted by a rail carrier and certified or commissioned as a police officer under the laws of a State transfers primary employment or residence from the certifying or commissioning State to another State or jurisdiction, the railroad police officer, not later than 1 year after the date of transfer, shall apply to be certified or commissioned as a police office 1 under the laws of the State of new primary employment or residence. 1 So in original. Probably should be “officer”. During the period beginning on the date of transfer and ending 1 year after the date of transfer, a railroad police officer directly employed by or contracted by a rail carrier and certified or commissioned as a police officer under the laws of a State may enforce the laws of the new jurisdiction in which the railroad police officer resides, to the same extent as provided in subsection (a). A State may recognize as meeting that State’s basic police officer certification or commissioning requirements for qualification as a rail police officer under this section any individual who successfully completes a program at a State-recognized police training academy in another State or at a Federal law enforcement training center and who is certified or commissioned as a police officer by that other State. Nothing in this subsection shall be construed as superseding or affecting any State training requirements related to criminal law, criminal procedure, motor vehicle code, any other State law, or State-mandated comparative or annual in-service training academy or Federal law enforcement training center.
