SPTCO 1953 M5

This horn is a 1953 B53AS Date code Southern Pacific M5. All the chambers and manifold have matching B53AS Date Codes indicating the horn was built in 1953 by Nathan Airchime. This horn has been media blasted and clear coated but still retains a small amount of SP black inside the bell throats. Unlike most M5s, this horn plays a Major 6th chord, as opposed to the usual A Dominant 7th.
Horn Rig: 185 CFM Diesel Tow Behind compressor at 125 PSI into an 80 gallon tank and a continuous stage Viloco valve feeding the horn.
Recording Location: Highway 39 in Azusa California

The horn blows at 00:30 are some of the most beautiful echos I've ever heard from an train horn. The M5 is a masterpiece.

[@ARC9652]

I could fall asleep listening to those wonderful echos..

ARC9652 Productions Same train horns have this Echo that is just so beautiful.

@@OfficialKlausMelodyne.UA-cam I hear you (no pun intended) but this one is unique. Sure it’s similar to a k5 but this has a spookiness all of it’s own

[@IceFoxTrainSpotting]

Even though I wasn't born in the 1950s please bring flashback to the F unit locomotives

[@SouRwy4501Productions]

And the Southern’s E units

Be great to hear at 2 o’clock in the morning talk about awesome chills, growing up and down your spine

I wish locomotives used B major 6th M5 horns like these today. Those echoes are indescribably beautiful!

[@christophercarey3232]

So do I, but unfortunately, in an "Intellectual Property" driven country like this, even musical chords are patentable.

[@sp9392]

Nothing like the sound of a Nathan M5. Beautiful.

[@deadaccount9826]

This Nathan M5 Airchime has the most beautiful musical chord 🎵🎶

[@therookie9276]

The major 6th chord makes it sound like a K5LA when it eerie sounds or echos. Great video

[@NolanLayland]

Absolutely gorgeous sounding horn. Great recording!

[@ianisaacs2340]

The M3 has been my favorite since I was 3, but DAMN I LOVE THIS M5!!!!! Definitely is the most musical and haunting horn I have ever heard. I want to be in the fog on an eerie night by the tracks while this horn echoes closer and closer. That might actually make me nervous there was a ghost train coming. And if there was such thing as a ghost train, this would be the horn.

Here comes the City of San Francisco, highballing out of East Truckee headed for Reno and points east. Very nice recordings! You're lucky to possess such a wonderful horn.

I can hear the Trainmaster powered commute heading into Millbrae now.

[@brodybombardir915]

That's gotta be the best M5 I've ever heard

[@ChargerusPrime]

This is the most ethereal thing I've ever heard.

[@steampunkrailvideos7374]

That’s an outstandingly amazing sound...

[@lilmacfarlan3]

I’m imagining hearing the sound of this horn traveling between 2 mountains. That sound travels a ton

[@TheAustinSubRailfan]

Why the cursing tho?

The most magical and musical horn ❤️🎵🎶

There was or maybe is a recording of these M5s in the Recording called " Interurban Memories & Mister D's Machine. "

San Joaquin Daylight #51 coming into Lancaster, Calif. blowing for Lancaster Blvd, right where the station used to sit.

[@RailfanDaniel]

Is this a 5/16" horn? I ask because the 1 bell is quite dominant, which Mr. Berry said was a common thing among the large orifice M5's.
In the last 30 seconds, it sounds very similar to some of the better sounding early 2000s K5LA's I heard on Amtrak P42's when they were over a mile past. It must be that they tended to be less brassy sounding than most K5's. Of course this was before the heated back cap days came.

[@hornhub3410]

This was formerly a 5/16th inlet horn that has been choked down to 3/16th by installing hex plugs inside the horn. This horn plays the same Major 6th chord that was commonly heard on K5LAs cast mid to late 90s. When pitch shifted downwards, my 1996 square tag K5LA sounds very similar to this M5.

[@ericgriswold1268]

The M5 appeared on B&O E-8's and 9's as well as Ackron, Canton and Youngstown FM H-16-44's.

[@Paul1963music]

De 1953 son las bocinas ?????

[@annieslots2941]

Beautiful

[@roachaximus5899]

The echo sounds life a K5LA, its so beautiful, it makes it seem like K5LAs are based on M5s

[@nathanmahoney6346]

Well, both are 5 chime airchime horns so...

[@lilmacfarlan3]

God I want this horn

[@amtk415w]

Here comes the Overland!

[@HunterR909]

I was searching for the horn with 3 horns forward and two back.

[@HunterR909]

But, I have seen several photoes of SP F7P, FP7s and other passenger diesel locomotives M5s have one lower and one upper bell/horn in the reverse position, and that seems the norm than the exception.

[@daylightbigboy]

Could very likely be off of an SP trainmaster.

[@HunterR909]

Why did you put all the horns facing forword, I thought that the passenger Fs and FP7 were three forward two facing backward?
