diction and authority
Some railroad police officers are certified law enforcement officers and may carry full police and arrest powers. The appointment, commissioning, and regulation of railroad police under Section 1704 of the U.S. Crime Control Act of 1990, provides that: "A railroad police officer who is certified or commissioned as a police officer under the laws of any one state shall, in accordance with the regulations issued by the U.S. Secretary of Transportation, be authorized to enforce the laws of any other state in which the rail carrier owns property."
It is important to note that Section 1704 also states that this police authority is to "the extent of the authority of a police officer certified or commissioned under the laws of that jurisdiction". While railroad police officers may have general peace officer authority in some states such as California, they are limited to the railroad's property in other states.
The status of railroad police officers varies by state, in that they are commissioned by the governor of the state in which they reside and/or work in and they may carry both state level arrest powers and some interstate arrest powers as allowed by 49 USC 28101. Although railroad police primarily enforce laws on or near the railroad right-of-way, their police officers can enforce other laws and make arrests off of railroad property depending on the state in which they are working.
Depending upon the state or jurisdiction, railroad police officers may be considered certified police officers, deputized peace officers, or company special agents. In Virginia, for example, any railroad may file an application with the circuit court of any county where it operates to allow the president of the railroad to appoint members of its own police force.
Some of the crimes railroad police investigate include trespassing on the right-of-way of a railroad, assaults against passengers, terrorism threats targeting the railroad, arson, tagging of graffiti on railroad rolling stock or buildings, signal vandalism, pickpocketing, ticket fraud, robbery, and theft of personal belongings, baggage, or freight. Other incidents railroad police investigate include derailments, train/vehicle collisions, vehicle accidents on the right of way, and hazardous materials releases.
