A classic Santa Fe horn on Santa Fe 941

[masterownerlml]

That engine has seen better days...

[JetMechMA]

He proposed that this misconception might occur because the intensity of the sound increases as an object approaches and decreases once it passes and that this is misperceived as a change in frequency."

[JetMechMA]

"Craig Bohren pointed out that textbooks erroneously state that the observed frequency increases as the object approaches an observer and then decreases as the object passes the observer. The observed frequency of an approaching object declines from a value above the emitted frequency, through a value equal to the emitted frequency when the object is closest to the observer, and to values increasingly below the emitted frequency as the object recedes from the observer.

[JetMechMA]

Hey, whats going on there? It looked like the truck trailers being piggy-backed were hooked directly together and had a set of train wheels attached somehow. Yes?

[unionpacifictrain]

i like the going away sound of the horn the most!

[JetMechMA]

@unionpacifictrain: i like the going away sound of the horn the most!

JM: Some viewers might not know about, "The Doppler Effect." Doppler is the scientist who defined this effect and it is that sound....or light...is affected by the relative speed between two points. Between fixed points the speed of sound (or light) will be the same, about 1100 feet per second for sound. But when at least one of the sound generators is moving, the speed is either added or subtracted, it changes the sound.

Thank you for sharing; "thumbs up" :-)

[nashgallo]

I love Santa Fe's GE horns

[badgerbuddy]

i miss the old santa fe paint scheme. both the red&silver, and the blue bonnet. at least in most cases they just threw BNSF's logo under the loco#, but it just isn't the same. loved santa fe

[NSalex12]

Awsome Leslie and cool echo.

[kylecascadden]

Which leslie is it?

[wexfordman20]

thats a dash 9 with old style trucks

[gaycowboy31]

very nice I just saw a former Santa Fe warbonnet in the sideing at North Metro Jct ouside of Krum Tx a few days ago it was Warbonnet red and unpatched no BNSF lettering anywhere on it anywhere and in the lead the crew told me they hated it but I dint have my damn camra with me to get a shot oh well

[Dialga1241]

oh I was compareing BNSF4723 trucks and this ones there so diffent sorry my mistake

[Dialga1241]

Thats a dash 9 because a dash 8 is a 2 Wheel boogie locomotive

[Pup1234567]

no thats a 6 axle dash 8. compare the trucks on 941 to a dash 9. the dash 9 has GE Hi-ad trucks on it very much like the ES44

[RailsandRoads]

@Dialga1241 what you are thinking of is a B40-8W this is a C40-8W

[pengapop12]

@RailsandRoads omg u guys, this is an ex sante fe warbonnet dash 8 40cw with a leslie rs3l on it, there end of story, wah do some research before u comment i dont mean to sound harsh or rude but im gettin tired of correcting people

[BNSF9250]

@pengapop12 shutu p

[moon47mars]

I think that is a Leslie RS3L.

[BNSF9250]

well duh

[avatarfan190]

i live right next to there!!!!!!!!

[caterpillero]

that horn sounds like a florida east coast railroad horn.

[firealarmtech7]

GO DASH-9 GO

[CoasterFan2105]

Thats a -8, not a -9..

[HamiltonOhrailz]

Was that an NS or BNSF train?

[trainsruleandroll]

a tiny bit high piched rs3l? but still AWESOME!!! very classy :D

[rsppap]

You are right that is a classsic Santa Fe horn. I think it's a shame thier bieng sold out!

[ElAviator72]

Beautiful Leslie Supertyphon!!!! Wish the BNSF had kept the Leslie horns

[tipdrip215]

there are still plenty of leslies left on BNSF.

[Doobie1975]

Was the ATSF 941 a C-40 Unit or an AC4400 unit?

[IC1034]

ATSF 941 is a Dash 8-41CW. It's one of the 25 Dash 8-41CW units on the BNSF roster.

[TheGondorian]

saginaw, where cheese is still cheese

[zozey1231]

Why doesn't someone make that horn usable in MSTS???

[BNSFman08]

This is the first time Iv`e heard an RS3L, all my friends have been talking about it,lol they will be worshiping me when they hear the news. great vid

[fafnir242]

Nice horn. Love it!

[TheUPBNSF]

road railer trains should be used more often (like stack trains and piggyback trains are) on the BNSF and UP railroads.

[NiallMS]

We could do with trains like that in the UK. Get some of that traffic off the roads.

[RCdash9]

I like that RS3L horn. It reminds me of Conrail.

[celica825]

@RCdash9 it totally does for me too.

[brianberlin]

long long short long... yeah

[NsTrainMan07]

What are them cars called? Road rails? do they have them for HO scale?

[Caltrain927]

Roadrailers

[CSX700]

that is definatly a RS3L not a prime!

[UPTRAIN]

Nice horn. Too bad it's was a BNSF Unit.

[mafarnz]

I love the Leslie horns. The RS3L has a good sound, but my favorite is the RS5T.

[tipdrip215]

i agree. the RS5T is the king of all train horns, but the RS3L is on up there too tho

[L324RE12]

Carefull now fella's. It COULD be a Prime 920 as well. A direct copy of the S-3L, after Leslie let the patent run out on the S-3K & S-3L horns. Almost identical in sound, But the Prime horns never used the spiked power tabs.

[Miketherailfan]

Alot of people mistake RS3Ls on the semi-older GE power for Prime horns. The RS3L on this particular GE is set on the full orfice setting, giving out a louder sound.

[mafarnz]

THANK YOU!!!!!! Someone who actually knows. I have seen way too many people mistaking Leslie's for Prime horns. ATSF didn't use Prime horns people....

[tipdrip215]

most of the prime horns were used on BN.

[CRPULSE300]

Nice catch. The roadrailers to Sagniaw usually run after dark.

[Hiei2k7]

I remember that sound...BN used to have some S3s in operation in Illinois...Cutting through the crisp fall and winter air.

[NS4100]

the S3s your referring to that BN used (to my knowledge) was just the RS3K

[Hiei2k7]

That's probably it, seeing as after hearing this again, the S3s i remember were a little off this tone, but relatively the same.

[theup3985]

I never understood why UP did away with their RS-3L's; that was the worst move they ever made. I'll never forget hearing those all the time on UP trains back in the 90's. What a great horn!

[lotusbandicoot]

Wow. You guys must be trained to identify a horn!

[NS4100]

We're not trained, it's just something we get bored enough to do to keep us interrested in trains, but it's sites out there to help you out, and there is plenty of people online you can talk to and ask, even me!

[oklahomaduster]

A classic RS-3L, Rare as can be on the UP now, glad to see BNSF still takes the time to clean/tune them insted of chunking them in the ditch & putting a K horn on, yuck.

[Miketherailfan]

NS has a good chunk of RS3Ls on ex-Conrail units.

[tipdrip215]

yes K horns are just way too common now.

[blazian1011]

i live the warbonnet

[cnnw3929]

Santa Fe had their own exclusive version of the Leslie S3L. One day, these horns will be replaced, and videos like this will be the only way to hear them in service.
