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
