Manatee vocalizations are detected by performing a variety of frequency domain processing operations on sound signals detected in an underwater region. The switch is configured to operate without the use of vital communications links to a central location, or requiring a central dispatching system or requiring a vital processor such that the wirelessly controlled railroad switch maintains its status as a railroad switch in a dark territory.
