Interim final rule.

FRA is issuing rules to require that a locomotive horn be sounded while a train is approaching and entering a public highway-rail crossing. The rules also provide for an exception to the above requirement in circumstances in which there is not a significant risk of loss of life or serious personal injury, use of the locomotive horn is impractical, or safety measures fully compensate for the absence of the warning provided by the horn. This rule is required by law.
