Leslie Control's "Supertyfon" RS Series locomotive horns are very powerful horns.  The RS Series is available in single, dual, triple, quad, and five chime configurations.  These horns feature a cushioned stainless steel diaphragm that has a molded-on silicone ring to reduce metal-on-metal wear.  RS horns have been tested to -65°F, and are considered to be resistant to freezing.  All parts are interchangeable among the RS series, and any bell(s) may be reversed for multi-directional signaling.  The most common RS Series horns are the RS-3L and RS-5T.
