Installing an aftermarket train horn on a private vehicle in Rhode Island is not prohibited. Rhode Island train horn law is in R.I. Gen. Laws §31-23-8 — “Horn required.” Standard UVC pattern: 200-ft audibility, ban on any horn that emits “an unreasonably loud or harsh sound or a whistle,” use limited to safe-operation cases. Violations fall under the civil-fine schedule at §31-41.1-4.

Install is legal; use on RI public roads — Providence, Warwick, Cranston, Pawtucket, East Providence, Newport — is the regulated behavior.

What R.I. Gen. Laws §31-23-8 actually says

§ Statutory excerpt

Every motor vehicle when operated upon a highway shall be equipped with a horn in good working order and capable of emitting sound audible under normal conditions from a distance of not less than two hundred feet (200′). However, no horn or other warning device shall emit an unreasonably loud or harsh sound or a whistle. The driver of a motor vehicle shall when reasonably necessary to insure safe operation give audible warning with his or her horn but shall not otherwise use the horn when upon a highway.
