[HD] The Sounds Of A General Electric P42DC Locomotive

- With the end of the Genesis era slowly coming into view, it is probably a good idea to capture these locomotives while they're still the main face of Amtrak. In this video, I decided to continuously record an example of a P42 Genesis locomotive in the idling position. I suppose you can consider this as a P42 ASMR video.

I don’t want these engines to retire. They’re so iconic!
Tyler Mac me too
They not fully retiring bro they’re going to do short city to city routes not long cross country state to state routes anymore
I know they are so cool looking
@@mrjohnson20123 I know, it's when they retire.
The same could have been said about the P42s and P40s replacing F40PHs…
11:16 No matter how bad of a day you're having, this sound instantly makes it 10x better!
What is that sound???? I've always heard it getting off the train and never knew what it actually was
@@ApolloBoyothe air compressor but the whoop sound is only on ge made engines
@@ApolloBoyo"pfffst, bwuaaaaaii"
Best sounding locomotive they ever made. From the whoop to the motor idle. You can feel it rhythmically thumping you in the chest to your feet.
I love the sound that those diesels make,especially the whoop sound that the air compressor makes when it starts up.
Man. The GE 7FDL engine is so relaxing. And the K5LA.
Love the sounds on these locomotives.
The diesel engine (prime mover) sound is coming from the head-end-power locomotive. Which is running at a constant 900 RPM (even when accelerating) to provide electrical power to the coaches. One the two locomotives (it seems to be the second one) is purring at 200 RPM. You can't hear it unless you're right next to the prime mover.
Because the head-end-power alternator is driven by the diesel engine (prime mover). So, in order to provide a steady voltage to the passenger cars it needs to run at a constant speed (900 RPM). Now, the more power you demand from an alternator/generator, the harder it is to turn. So, you need more power from the engine to maintain the RPM. When you're accelerating, especially if you're in notch 8, the traction motors are demanding a lot of power from the main alternator, which makes it very hard to turn. So, in order to maintain 900 RPM the diesel engine needs to add more power. That's why in head-end-power mode, when the train is accelerating the rhythm of the engine stays the same, but the noise becomes louder and "grouchier".@@theonlyshortsalot
Both units are not use to pull the train? Only 1 unit pulls and the other provides HEP?
Both units pull the train. One unit has all of the horsepower available for traction, the unit providing HEP has whatever horsepower is left from the HEP load.@@JaySpec13
@@JaySpec13 From redditors I've been told that 800rpm constant is needed to both pull the train and to reach 60hz to power the railcars. So I think both locos could be pulling.
@@JaySpec13 they both pull but only one provides hep
11:16 WHOOOP
They have motors you can both hear and feel, should you get close to one - like when you’re getting ready to board.
Also, these have a little *soot* when pulling hard, which I find somewhat romantic and a connection to the past.
5:35 We Also Hear This Whoop Sound On Every Engine Steam Sounded From GE ES44AC, Dash 9-44CW and AC4400CW.
I was starting to wonder if he was going to move
Soonest effective sound for us, real train lovers
So addictive!! 🔥🔥
I loved hearing F40's left in run 8 during station stops in Southern Pines, and Hamlet at night (91/92 , southbound).
I commute on the MTA Danbury line every week. The branch line diesels really know how to make an entrance compared to the main line EMUs.
The alc could never 😅😂😂
OK, can anyone tell me what that funny noise is after the locomotive starts to roll? not the bell or the whistle, but like something spooling up!!! thank you
if you talking about the whoop sound, its the air compressor startong. you can only find these exclusively on GE locomotives
Beautiful iconic p42s ❤I'm from england and i love them did the California zephyr when i was last over can't stand those pig ugly chargers !!!
Why a ten minute station stop? Even the Coast Starlight that I've taken many times has looooong station stops, even at little podunk middle-of-nowhere stations where only a handful of passengers get on or off.
If i remember correctly Cary is an extended stop and i recall having to do two stops to service the coaches and sleepers separately
P42DC’s are not electric
General Electric (GE) is the company that produced the P42DC.
Genius in the house🤓
They are part electric the diesel engine drives a generator which then supplies electricity to the traction motors which sit in between the wheels !!!!a basic answer!!!
GE Junk you mean
You mean the locomotives that Amtrak has used since 1997? The locomotives that have reliably stayed in very active revenue service for almost 30 years and still going strong? The locomotive that beats the ALC-42's 8 times out of 10 for reliability? The locomotive that doesn't need help from an older engine in colder climates? The locomotive that is much more fuel efficient that the new ones? The locomotive that's worlds easier to maintain than the new?
Yeah, I'll stick to my GE Genesis locomotives. We'll pass you going 80+ while you're in a siding trying to figure out why you're engine won't work in the freezing cold.
