So, Amtrak Police are both federal law enforcement and railroad police, correct? At least in my state, federal law enforcement (with one specific exception) have to be authorized by a local law enforcement head to enforce state or local laws, except in the case of an "emergency". Even the FBI doesn't have that authority unless invited or given that specific authority. I heard of one county where the Sheriff rescinded the authority of Forest Service law enforcement to enforce state/local laws in his county. However, railroad police in California are specifically given the the authority of a state peace officer.
I'd like to see any statutory support for this theory.

(a) Federal criminal investigators and law enforcement officers are not California peace officers, but may exercise the powers of arrest of a peace officer in any of the following circumstances:
(1) Any circumstances specified in Section 836 of this code or Section 5150 of the Welfare and Institutions Code for violations of state or local laws.
(2) When these investigators and law enforcement officers are engaged in the enforcement of federal criminal laws and exercise the arrest powers only incidental to the performance of these duties.
(3) When requested by a California law enforcement agency to be involved in a joint task force or criminal investigation.
(4) When probable cause exists to believe that a public offense that involves immediate danger to persons or property has just occurred or is being committed.
In all of these instances, the provisions of Section 847 shall apply. These investigators and law enforcement officers, prior to the exercise of these arrest powers, shall have been certified by their agency heads as having satisfied the training requirements of Section 832, or the equivalent thereof.
This subdivision does not apply to federal officers of the Bureau of Land Management or the United States Forest Service. These officers have no authority to enforce California statutes without the written consent of the sheriff or the chief of police in whose jurisdiction they are assigned.
(b) Duly authorized federal employees who comply with the training requirements set forth in Section 832 are peace officers when they are engaged in enforcing applicable state or local laws on property owned or possessed by the United States government, or on any street, sidewalk, or property adjacent thereto, and with the written consent of the sheriff or the chief of police, respectively, in whose jurisdiction the property is situated.
© National park rangers are not California peace officers but may exercise the powers of arrest of a peace officer as specified in Section 836 and the powers of a peace officer specified in Section 5150 of the Welfare and Institutions Code for violations of state or local laws provided these rangers are exercising the arrest powers incidental to the performance of their federal duties or providing or attempting to provide law enforcement services in response to a request initiated by California state park rangers to assist in preserving the peace and protecting state parks and other property for which California state park rangers are responsible. National park rangers, prior to the exercise of these arrest powers, shall have been certified by their agency heads as having satisfactorily completed the training requirements of Section 832.3, or the equivalent thereof.
(d) Notwithstanding any other provision of law, during a state of war emergency or a state of emergency, as defined in Section 8558 of the Government Code, federal criminal investigators and law enforcement officers who are assisting California law enforcement officers in carrying out emergency operations are not deemed California peace officers, but may exercise the powers of arrest of a peace officer as specified in Section 836 and the powers of a peace officer specified in Section 5150 of the Welfare and Institutions Code for violations of state or local laws. In these instances, the provisions of Section 847 of this code and of Section 8655 of the Government Code shall apply.
