Featured in this lot is a Vintage 1980s Leslie SuperTyfon RS3L Train Horn. A horn is one of the many safety appliances installed on a locomotive and is used to warn both the general public and railroad employees while in motion. Locomotive horns date back to the steam days, with single-bell horns generally applied on a steam locomotive. This practice was carried over to the early diesel locomotives before the multi-bell horn began to see increased use in the industry. With a multi-bell horn, freight railroads would typically reverse one or more bells to provide warning toward the rear of a locomotive when it’s operating backward. Leslie horns were common on new locomotives years ago, Dating back as early as 1934, the Leslie Tyfon model of horns could be found on railroads. In 1935 Leslie made the Leslie-Tyfon air horns for the first Burlington Zephyr locomotives. Leslie-Tyfon horns became the standard on most American railroads. Leslie's horns were the most popular locomotive horns, and the standard for GM Electro-Motive Division models. The SuperTyfon horns first appeared in 1951 as a replacement for the failed Chime-Tone series of multi note horns. When the SuperTyfon horns first came out, they were still called Chime-Tone horns which eventually evolved into "chime whistles". Note that Leslie has always called their horns "whistles". The S-3L was introduced in the early 1950's and was used extensively by the Santa Fe, Union Pacific, Milwaukee Road, Soo Line, Missouri-Kansas-Texas (MKT), Chicago & Northwestern, Kansas City Southern, Erie Lackawanna, Reading railroads, and many others. This Leslie train whistle features a low profile manifold with three spiked backed cap bells, #31, #37, and #48; #48 is in a reverse configuration. Bells and manifold are stamped "Leslie SUPERTYFON".
