S1 whistles

[NW Mailing List]

 Whistles (horns, too) can break into high level harmonics, sometimes called overblow,.  Various squeaks and squawks can be caused if you have the right technique on the whistle cord.  The recording you're referring to on Thunder on Blue Ridge, is a great example of what can happen with a single chamber whistle.  "The Great Whistle Storm", as Link called it, is a sustained example of a high harmonic, which as I recall, returns to the normal pitch for the last long crossing blast.  Bud Swearer's N&W recordings also feature a similar phenomenon, but his recordings are very hard to find nowadays.

  While on the subject, O Winston Link's recording (33 rpm) of Hooters on Blue Ridge renders a triumphant blast of the pusher crossing the crest at Blue Ridge followed by a high-pitched scream of some whistle I always thought was something the fireman was playing with - any comments? Ron Hash

 Well, here’s what I remember. First – the 475 has a hooter with a seven-inch bell, shorter and higher-pitched than the standard 12-inch (?) hooter.  My understanding is that the 7-inch hooter was replaced by the 12-inch job; I don’t know where the Strasburg got a 7-incher.  The sounds of the regular hooter varied as to the boiler pressure of the locomotive to which they were attached.  The A and Y-5 plus engines with 300 punds sounded different than the K_1/S-1as with 220.  The Ms with 200 pounds didn’t sound too much different than the 220s and the Y-3/3a/4 with 270 didn’t sound too much different from the 300-pound engines.  And there was always F. T. Nichols’ screamer which he used on the Abingdon Branch. The passenger engines of the streamlined engines were handicapped by being down inside the skyline casing and the Ks with 220 pounds sounded different from the 300-pound Js. For my money  the best sounding chimes were those on the two Pacifics used on the Clinch.  They were out in the open on the side of the steam dome, and they’d echo down the hollows along the Clinch and make you homesick on your own back porch. - Ed King From: NW Mailing List via NW-Mailing-List Sent: Friday, January 31, 2020 3:57 PMTo: NW Mailing List Cc: NW Mailing List Subject: Re: S1 whistles Using the same freight whistles as the A, Y, etc sounds reasonable. Were there 2 freight whistles? The reason I ask is because the hooter I have heard on all recordings of the A, Y, Z and all sounded different from what I have heard on recordings of the M's. Boiler pressure? The whistle USUALLY used on the 475 at Strasburg has a different sound than the "hooter".  I think the BP may be the reason the K-2 sounds slightly different than the J as I'm told they had the same Hancock whistles. Is that true?
 I think the N&W should have copied the special whistle from the 382 and used that one more!

I don’t see why N&W would design a special whistle for the switchers when their standard whistles were probably readily available. 
 I have Bill Bauer’s recordings from 1958 and some are noted as S1 or S1a engines. There may be some whistling on one of them.
