Here is another extended edition audio recording of the Bombardier MITRAC AC traction motor inverters on the R179, recorded on the A train (IND 8th Avenue Line, Dyckman Street to 135th St. & 59th Street - Columbus Circle to Chambers Street) for openBVE development purposes. Next recording to come from the IND Rockaway Line ( • NYC Subway HD Audio: B... ). Enjoy =)

I rode theR179 maybe twice or three times, and I wasn’t sure what I think about the sound at first. But it grown on me a few years later. Could’ve used a different motor sound, but I guess this is ok! what do you guys think about the sound?
The problem with getting 3 phase sounds for OpenBVE is the second sound, The first sound is easy for the 179 because it's steady, the third on is good because you can get a steady section that you can then use ad adjust pitch too. The second one though has constant pitch changes and when it reaches it's nominal level switches to either the 3rd phase if accelerating or 1st phase when decelerating. Making it almost impossible to get a steady sample that can be manipulated in OpenBVE
tf51d I’ve already found a solution to this with my Siemens pack and I’m using a similar method on my R179
Even though it’s not absolutely perfect, it’s within the limits of OpenBVE
For Phase two take this video at about 7:25 you will have a good second or two to sample. Use RUclips2mp3, use any sound program you want, I use Audacity. Clip that sound byte and effects > repeat > reverse. Then make it as long as you want.
Her announcements sound so good. I wish she voiced the other lines that dont have hers.
I prefer the Broadway announcements much more.
I prefer Jessica she bold and loud and get to the point
The announcements 😍. When it says A Express train it reminds me of the R110B
God those propulsion motors sound so nice! I like the older MITRAC motors on the R143 and the R142A more then the newer ones on the R179 but it sounds completely sick!
I know right. Those screaming high pitch propulsion motors is crazy good. I gotta venture to New York one day.
For some reason when at slow speed, R179 sounds like Taoyuan Airport MRT, which uses Mitsubishi Electric IGBT-VVVF.
Were you outside the whole time or did you just stick it there and left it
Took a risk and left my camera on the floor while I stood on the other side of the door inside the passenger compartment. As far as I know, I wasn't breaking any rules lol. #Loophole
@@FanRailer well I'm glad you didn't lose it. In future, I would suggest you strap it up to the floor in some way.
Really don't need to. Gravity is plenty force to keep the equipment from moving around too much. The trains don't accelerate or brake fast enough to cause them to slide off the anticlimbers.
Interesting place for a camera...
Well, it's a good place to record the audio.
Very relaxing to have on in the background, thanks!
No (A) local program yet?
Put The Camara On The Front Of The Train Car!!
Why would he do that?
The Real Question Is How Can He Do That?
Is the camera stuck onto the platform with a magnet?
No it isn't
Great video! Any plans to film any other MTA stock like this? I love the sound of the R188s and Alstom R160s, or any of them for that matter!
Possibly.
Can you make more Long Island railroad videos
How did you even get the camera out there?!
Don't the doors open?
Open the end doors.
Only place you can't pass on an NTT is where the conductor or motorman sits.
It sounds like lemon
It is a lemon
I'm an electric vehicle consultant for a living. I'm curious why the pwm switching is so pronounced and loud on these setups in the R179?
I mean I'm sure it's loud because of where the camera is outside the train but usually this isn't that noticeable in most vehicle setups unless you're right on top of the motor or inverter.
I also wonder why they didn't change the frequency up or down a bit so it doesn't reverberate in the station so much?
Most powertrains will let you set the low speed pwm frequency to favor either smoothness and more noise over quietness and some potential vibration.
It's usually fairly use case and vehicle-specific if you go high or low frequency to make it as smooth and quiet as possible.
Thanks for the video!
Haha yea, I've always wondered from a volume perspective, the points you bring up. Especially when you have other manufacturers like GE who makes their locomotive inverters virtually silent. This would probably be something you'd need to ask an engineer from Bombardier about.
@@FanRailer I think it's a safety thing, for track workers to hear the train from afar. Especially in an instance where someone has fallen onto the tracks, they can hear the train from much further away.
May I Use This Audio For A Video? I Will Give You Credit
go for it!
@@FanRailer thx m8!
Where did MAXHD Go? He used this for a NYC train on roblox 0:47
Damn how did you keep the camera/phone so still in this scenario?
lol it is literally just resting on the floor....
Lmao
Works until a homeless dude making his rounds throughout the train kicks it over. Or do we only have that in Chicago?
Congratulations R179
Mmmmm
Sounds cool, looks ugly. Little bit too loud though. Gets annoying.
It's too loud because the camera is located closer to the motors/bogies and this is a part of the train car hardly anyone cares about, its only to move between cars
Superb video! Better than the R160A sounds!
Anything is better than the R160A/R142. But R188/R142A/R143 is still my favorite.
