If a passenger upon a railroad train refuses to pay his or her fare, or is noisy or disorderly, a railroad police officer may arrest him or her without a warrant, and remove him or her to the baggage or other suitable car of the train and confine him or her there until the arrival of the train at some station where the passenger can be placed in the charge of an officer, who shall take him or her to some place of lawful detention.
