The S-5T was introduced in the early 1950's as a replacement for the S-5D, and competition for the Nathan M5. As with the S-3L, the earliest S-5T's featured bronze power chambers and two-piece bells. The S-5T was a popular horn on Kansas City Southern, Illinois Central, MKT, Norfolk & Western, Frisco, and Chessie System. Santa Fe used the S-5T on most of its passenger diesels.

with spiked back caps came about in the 1970's with the goal of making the horns less susceptable
to fouling. RS-5T's tend to sound harsher and less musical than earlier S-5T's. Horn and photos

Prime Manufacturing Corp. of Oak Creek, WI offered a horn identical to the S-5T, which they called the PM-929. No PM-929's are known to have been produced, however. | |||||
Factory tuning was: 255, 311, 370, 440, and 554 Hz (approximately C,D#,F#,A,C#). | |||||
No large railroads have purchased the S-5T in recent years, but examples may still be found on older Illinois Central, CSX, and KCS locomotives. Norfolk Southern may have a few S-5T's left on former Norfolk & Western units.
Union Pacific's E-units #949 and 951 had RS-5T's as of mid-2000.
