They added the horns specifically because the whistle didn't cut through fog very well, and the Daylights ran in and around the very foggy San Francisco Bay area in revenue service.
@davidfuller581 Thanks for your reply, I guess horn is better because it is deeper in tone and directional (facing forward). Meanwhile, the whistle is omnidirectional and higher in pitch, making it harder to hear at a distance and in foggy condition. Horn play E2 165Hz [leslie tyfon A200 (if I remember correctly)] Whistle plays A,C,E. 220Hz, 261Hz, 330Hz [hancook long bell 3 chime whistle (if i remember correctly)] The reason for my question is because the whistle would use more steam than the Horn use air, And steam expand more. But, as you had just said. I guessed, by concentrating the sound to the front (which is needed the most) is better than having louder but scattered sound (including to the side and back and up) which is wasting it.
For those who's wonder why The GS-4 had a air horn is mostly cause of foggy conditions back in the day and plus it's better being heard than the whistle and cause of 4449s high speeds
I still don't get why a horn is easier to hear at high speeds because I'm pretty sure the whistle is louder, and all sound travels at the same speed. But I can kinda get why the horn was used when it was foggy out.
@@amtrak_121 if you think about The whistle is loud but the horn Can traveler Farther than the, Like Milwaukee F-7s due to their high speeds they only used a Air horn no whistle because its Easier to hear it from a far distance than than a whistle (well I guess Way far distances) for people know it coming.
@@bnsflover7062 First of all, I believe the F-7s actually did have whistles as well. Second, the horn sound can travel farther? How does that make sense?
@@amtrak_121 also the horn part: The horn is basically louder than the whistles because the whistle would be omnidirectional and it may not Have emit Sound At certain speeds As it should because it would be eaither place in some Difficulty locationsof the locomotive, Unless it's a Very loud type of whistle, But a Air horn is basically like a Very big Megaphone And could sound out Lots of Sound energy to where it could extract ears people, where it can be heard from miles Honestly I wish marslight still existed on other modern locomotive aside from metra units
That wasn't the Amtrak engine honking, that was 4449. The Daylight locomotives were equipped with Leslie A-200 air horns on the front, which carried their sound better than the whistle did in foggy conditions.
Because that would require traction motors on the trucks. Which would require a more powerful electric power output to operate than 4449 can generate without a diesel generator or motor added on. Which at that point you have no room for oil for the steam locomotive so you have to build another tender. It's just simpler and much better to use a diesel. Also it helps having a company with the trackage rights on your train.
4449’s regular whistle: *everyone cheers*
4449’s air horn: *everyone moves*
right on.
The whistle means "Hello", and the air horn means "Get out of the way!"
Whistle: “Excuse me, may you move please.”
Air horn: “MMMMOOOOOOVVVVVEEEEE!!!!!!”
Everyone moves? Is that better or worse than cheer?
3:40 airhorn
0:43 Whistle
3:40 Horn
So... which one is louder and better?

3:40: A damn thing of beauty!!!
The Leslie A200 Makes a low E note
Fantastic, makes me homesick for the Gorge, best railfan site. Thank you
Love that engine! Love the whistle and horn too!
4449 is great
She is one beautiful looking steam locomotive. Out of all of them 844 is my favorite and Daylight is the second on my list
Today most steam trains that survived are at museums but a few still run on the mainline
3:39 SP 4999 is reacting like diesel locomotive
That’s Because It Is ;) Ever Heard Of A Oil Engine ;-;
Steam_Dev No need to get so offended over it, I was younger at that time, calm the fuck down.
@@itsyaboybrandon7509 Um, have YOU ever heard of an oil burning steam locomotive?
@@itsyaboybrandon7509It’s a steam locomotive that burns oil instead of coal.
was 100 degrees that day! hence not much steam!
yeah i remember it was hot for both days not to mention on the Southbound run 4449 started a fire in the deschutes river canyon near north of maupin
Steam is most visible in colder weather
The crew must have been boiling inside of the cab
3:40 nobody: your phone vibrating:
Lmao how did I not notice this?!

Love the airhorn.
Lively, a fine vid, took me a while to figure out where, that must be Metolius at end.
Sp 4449's Leslie a200 air horn nickname foghron
I get the feeling bill was driving until Avery
It would be cool to see 844 and Daylight together like they did back in the 80s as they raced up Cajon Pass
Or the double-header
2:21 what the car doin?
Sp 4449 está aparecendo o ônibus
3:40 sounds like forward cab 4294
It sucks that SP used to Go to Denver well till today but with UP diesel engines.
I wish that she can come here to Denver. Just for one day.
the southern Pacific isn’t a railroad anymore
Y does she have a horn? Isn’t the whistle enough?
Horn carries farther especially in foggy conditions.
Safety mostly back in her heyday, an air horn can project farther than a whistle can, especially when approaching level crossings.
do you know where this train is going to
This is the return segment of a two-day trip from Portland to Bend, Oregon.
he is correct
going south?
The sterile air- or electronic-horn sound emanating from the Amtrak engine pales in comparison to the lively tones of 4449's steam whistle.
true but catching the air horn in action is rare i was excited when he used the air horn
That wasn't the Amtrak engine honking, that was 4449.
The Daylight locomotives were equipped with Leslie A-200 air horns on the front, which carried their sound better than the whistle did in foggy conditions.
correct the A200 is a good horn for foggy conditions to improve saftey
Who wins the race lol
10000
I don’t really like the whistle 4449 is currently wearing
Why can't they just incorporate a dynamic brake into the auxiliary tender to save us having to look at that hideous, hideous diesel?
Because that would require traction motors on the trucks. Which would require a more powerful electric power output to operate than 4449 can generate without a diesel generator or motor added on. Which at that point you have no room for oil for the steam locomotive so you have to build another tender. It's just simpler and much better to use a diesel.
