GTO-VVVF Inverter Sound outside of a Kinki Sharyo SLRV - DART

[@지브릴마후아체]

Our VLCs sound like this The motor is a AEG/Westinghouse 1504 A tri-phase asynchronous ones

[@LaneThePlane]

So THOSE are the cool dart sounds I love! Thank you for uploading this!

[@NTxRE]

Glad you enjoyed! Check out my newer video where I test a new recording device I made to capture the actual sound of the inverter!

[@24mootsmoots70]

Cool! Similar to the Taipei Metro C301... As a Japanese viewer living in Japan, I was surprised at how you can request a certain acceleration level (P1) when departing... That would be 99% impossible here in Japan, since everyone has to follow the time table 😅

[@NTxRE]

Fortunately our system in Dallas is small enough for the time table to not matter as much. It is very unusual to see people filming trains here though, so the train operators are usually surprised or confused. Thanks for watching!

[@24mootsmoots70]

@@NTxRE Ah, this is in Dallas, I see... Thank you for the nice video, it was fun for me to watch trains from other countries 😊

[@DFWRF]

Does anyone else like the voice they use for their dart trains? And announcements

[@NTxRE]

I think it's a pretty good voice! Easy to understand and listen to

[@coolleo149]

I can tell how very nice the female operator was and giving you bell salutes.

[@NTxRE]

Yes, I certainly appreciate the operators for being kind to photographers and videographers!

[@cablemanagement1524]

the dart SLRV was the first incuctor-recorded Ebara Express video i saw! it was a great way to kick off this obsession. i'll never forget its sound

[@NTxRE]

That's what got me interested too! I knew the tech existed, but for Ebara Express to make that video in my hometown with a homemade recorder, I couldn't help but figure out to make my own. I'm glad to know now that it's pretty easy and I'm thrilled I have one now! Thanks for watching!

[@charlesball6519]

When I heard the inverter sound a decade ago, I wasn't sure if that was it changing gears, because it sounds just like that (I had never been around an light rail train before). I guess back then, I wasn't aware that inverters could change the frequency of the incoming AC power. I rode DART that decade ago, and yesterday. (Both for the Texas State Fair)

[@NTxRE]

Cool story! It's funny to think in an electronic sense of the term, it is changing gears. The inverters have frequency limits, so to achieve higher speeds they remove pulses from the sine wave, giving it that sound. I hope you enjoyed the fair, and thanks for watching!

[@therealchayd]

Likewise! In the early-mid '90s here in the UK they started introducing the "Networker" trains that used GEC-Alsthom GTO-VVVF drives. When I first heard that gear-change sound I was completely baffled, eventually figured it wasn't gears, but never really looked into why motor controllers would need to do this (until now, where it makes sense), sadly those trains have been phased out in favor of quieter (and less comfortable) IGBT-driven trains (although admittedly, the new trains do make an amusing car alarm sound when running on third-rail power).

[@weeardguy]

@@NTxRE And that's why as a Dutchman I was quite confused when I boarded a Dutch LINT-train back in the first years of the new millennium. Being used to diesel-electric trains only, that just rev up to full maximum and usually keep doing so until they hit maximum speed (140 km/h), these diesel-hydraulic units feature a gearbox... Definitely a weird experience to be on a train that gets up to speed and right about when it gets to 60 km/h an hour or so, you notice how high in revolutions per minute it is and you feel like something's wrong, when just around that moment, the revs drop, things go quieter, to just hear it switch gears and power up again till you hit 100 km/h or so, when it changes gears again ;) The doubledecker trains basically introduced Dutch people to modern traction-electronics: the first Sprinter trains and Koploper trains did have semi-conductor electronics controlling the motors, but on the Sprinter trains you hardly noticed them and the Koplopers are not as prevalent, as they only use a short loud hum when overcoming their stationary resistance, which then turns into a hum that hardly changes in sound as it speeds up.

[@atomstarfireproductions8695]

They sound like Toronto T1 trains. Although I can’t find information on who made the propulsion system, I think it is older ADtranz 3 phase.

[@NTxRE]

Not sure what motors the Toronto trains have, but their inverters are the same Westinghouse units these trains have. The main differences are that the Toronto T1s have I believe 7-8 notches of power while the DART SLRVs only have 3. You can accelerate them much slower and hear the inverter better.

[@TheSearleFamily123]

@@NTxRE 3-phase is actually the type of power that the AC motor uses. It doesn't relate to the notches of power of the train. Since VVVF drives require a DC supply, this means that if your supply voltage is AC, it has to be converted to DC first.

[@gluse]

It doesn’t look like these older trains are gonna last much longer. I’d DART were to order more trains from Kinkisharyo I would recommend having digital signs instead of paper rolling signs because a lot of them get stuck and don’t match the rest

[@NTxRE]

They'll definitely need to start looking into something... Especially with D2 on the horizon.

[@josepho.8039]

I personally prefer the old roll signs that that have it’s more visually appealing to see especially the sign is rolling for a good bit of time. The main reason they stop working are from the motors burring out more easily now that there are over 30 different signs instead of the 10 compared to before all of the system upgrades

[@dfwrailvideos]

One of the more interesting slides is the “Express” slide. NTRE told me it was just a placeholder, but it would be cool to have an Express service!

[@RajaRhodes]

We already have two cars with LED signs. They’re prototype signs. LRVs 135 and 222

[@weeardguy]

@@josepho.8039 I personally prefer roll signs too. I can understand we don't have them anymore in The Netherlands (the oldest type of sign you will find in regular service on a train is a flip-dot display as still in use on the very few LINT-trains that are still running here). Amsterdam Combino trams recently got converted to LED-signs, after driving around with flip-dot displays for decades. The biggest downside to LED-displays to me is just their brightness. Flip-dots need to be illuminated though, but a roll sign still seems to provide a better contrast or just has a better spacing between characters instead of the rather fixed position of LED's on the electronic signs. Especially a 'not in service' display (which used to be white letters on full red display in the past) now hardly differs from a bus that is in service (trains that aren't in service don't show anything here). The buses were fun though in the past... when it would change destination at the terminus, on the older buses the driver would have to get up from his seat, open up a small kind door to look at a small mirror that showed the position of the roll and start rotating a lever by hand to change the destination. Though there was a small mirror, they usually asked the first passenger to confirm it was showing the right number and destination. The first electronic roll signs apparently could only count up and down from their fixed start and end positions: if, from the somewhat 80 destinations (or even more, I have never known how much there were on 1 roll) the roll could show, destination 20 was selected and it had to go down just 1 number, the computer would make the roll go through all the numbers above until it would reach the end, where the roll would reverse direction. Great to watch as a kid as it seemed the whole world would roll by as it was changing destination. All kinds of places and villages you had never heard of would slowly roll by.

If you look very carefully along the tunnel walls between Mockingbird and Cityplace there's a hidden room or cavern. Believe it or not many years ago there was originally going to be 2 subway stations one at Cityplace and the other at Knox/Henderson. That cavern is where the Knox/Henderson Station would have been built many years ago. Now why did DART not complete this station? Well the reason is many years ago when DART was constructing Knox/Henderson Station the neighborhood protested and they didn't want the station built so after many protests DART did not complete the station. Just south of the Knox/Henderson exit on 75 Central Expressway on the on east side on Willis Ave at the frontage road of the highway there's a huge shell shaped ventilation shaft that goes 80 down into the tunnel which can pull air or smoke of the tunnels in minutes of needed and you can smell the inside of the tunnel probably from passing trains. You can even hear trains thundering by at 65 MPH. Across Willis Ave from the ventilation shaft next to the La Quinta Inn near there are metal steel plates on the sidewalk and pedestrians walking over them may not realize they're actually trap doors and they open up into several flights of stairs going down down down to the rail line. So since the station was never built that ghost station only serves as an emergency exit from the tunnel and access for DART workers to go down and make sure everything in the tunnel is safe. Cityplace opened as planned in 2000. Sadly as of today DART has no plans to build Knox/Henderson.

[@NTxRE]

I've actually heard about this! It's hard to catch it while you're riding, but I've seen it. I think it would be really cool for them to finish their plans to add the station.

[@gluse]

I agree, but unfortunately there are no funds to build one and construction is underway for the new silver line with an anticipated opening in 2022

[@quavionthomas4151]

Same knox/Henderson station would have been completed if it weren't for the protesters

Yep, it's actually even older than Windows 7. I believe Windows XP was the debut of the sound.

Fun Fact: LRV 101 was to be labeled as 100, but because the original 101 was damaged in an earthquake and at unloading, it was rebuilt as 102.

[@NTxRE]

I didn't know that. That's cool to know!

[@railfanxjofficial]

So where is 101

[@dfwrproductions]

There is no 100. 101 which is now 102, was heavily damaged in that earthquake which occurred in Japan. 102 was also damaged and changed to 101. Their numbers were swapped but were not scrapped, and there is and never was an SLRV 100.

[@dfwrailvideos]

Cool! I was there a few hrs ago Fun Fact: the red lights on the back of the SLRVs are brake lights!

[@NTxRE]

Glad you enjoyed! I did know that fact, it's especially useful downtown for cars.

[@dfwrailvideos]

@@NTxRE When I was younger I thought they were marker lights, but then I saw in one of your videos that they came on when the train slowed down!

[@NTxRE]

Ah I see! Glad I managed to teach you something. Does that make this an education channel? Anyways, I remember noticing too. I imagine once upon a time there were more times the train drove next to cars, but now there is much more dedicated infrastructure. Still cool though!

6:29 What's the name of that type of horn they use

[@NTxRE]

I wish I could tell you, but I don't know. I've looked online myself to no avail. I'm sure there's a horn expert lurking around here somewhere who can step in. Sorry!

[@DJShuffle07]

@@NTxRE no worries, I ride the dart light rail everyday to work, and trust me I've already use the sound recording app on my phone and the sound of horn came out crystal clear 🏆🏆🏆

[@josepho.8039]

Well that’s actually the whistle dart LRVS have both a whistle and a horn the whistle being used for grade crossings and entering and exiting the tunnel as seen by the one long blow, the whistle when it actually works and sounds good plays a nice tune in my opinion. Now the horn is is also used a grade crossings mainly on the blue line but also at certain parts of the green line. I’m the cab the horn button pressed right next to the gong/bell and next to that you should see a lever that being the whistle both being air powered. Though some people think they are the same they are totally different I’ve been trying to figure out what kind of horn and whistles they use for the longest time some say the horn is an RS3L I honestly don’t hear it but anyway that’s my two cents sorry for the long train nerd rant. Hope this was helpful

[@dfwrailvideos]

The horn is actually a whistle. Some trains mad early in certain countries have a “power” setting for the train horn. Push it up and you get the whistle-like sound. Pull it down and you get a horn sound.

[@RajaRhodes]

And there’s actually 4 power settings. PMin is the lowest in power. You should record me one day. I’ll give you a whole show!

[@NTxRE]

That would be great! I'd love to learn more about them. If you're willing, contact me through Instagram , or let me know how I could best reach you.

I’m a rail operator at DART. You know when these sound the best? When we turn off the A/C unit. Then you can hear it crystal clear

[@mp6471]

This fantastic train's engine sounds a lot like some metro trains here in Italy, being they the MA 200 from Rome, Meneghino and Leonardo from Milan and the M1 from Naples. Also the TAF from Trenitalia.

I'm glad I got to do it! We're a long way away on these trains from automation, but I'm sure it'll happen someday.

[@RobloxTrainspotting]

It sounds like the ttc t1 and the r110a

That would be because those three trains (and a few others) share the same inverters! I'm hoping to see the TTC T1 soon

@@NTxRE The fact that other transit agencies share the same inverter/motor/propulsion sounds made me show some love for them.

It is the same. These are very rare inverters. The Toronto TTC T1 is also the same. Thanks for watching!

[@MP11931]

There are literally so many trains/trams that sound the same, which are: Toronto TTC T1 NYC MTA R110A Taipei MRT C301

[@NTxRE]

The R110A is permanently decommissioned, and what's left is decayed beyond any sort of use, the Taipei MRT C301, last I checked was in process of being phased out, and the TTC T1s are the only ones as plentiful as DART. The LA metro if I remember correctly has a LRV with these inverters. Westinghouse inverters are rare. Everything else is from a more common brand such as Bombardier, Hitachi, Toshiba, or Alstom just to name a few.

[@MP11931]

I see, but the R110As are actually still being used as a work train, it’s permanently decommissioned from passenger service but the T1 is going to retire soon and is also going to be used as a work train I believe.
