(a) General. If a railroad police officer certified or commissioned as a police officer under the laws of a state or jurisdiction transfers primary employment or residence from the certifying or commissioning state to another state or jurisdiction, then the railroad police officer must apply to be certified or commissioned as a police officer under the laws of the state of new primary employment or residence not later than one (1) year after the date of transfer.

(b) Interim period. During the period beginning on the date of transfer and ending one year after the date of transfer, a railroad police officer certified or commissioned as a police officer under the laws of a state may enforce the laws of the new state or jurisdiction in which the railroad police officer resides, to the same extent as provided in § 207.5(a).
