The actual sound itself is caused by a byproduct of how the software for the VVVF drive (using GTO thyristors as the transistor technology) has been programmed. GTO thyristors have a limit on how fast they can pulse at, meaning we need to cut out some pulses upon reaching a certain speed so that the transistors don't get overloaded. The pulse-width modulation is what causes the sound, meaning that each time pulses are removed, the sound jumps back down. The overhead voltage AC/DC and third rail voltage DC usually makes no difference in the motor drive package; VVVF drives pulse out artificial AC waves, meaning your motor should be an AC motor in a 3-phase configuration, or a permanent magnet motor (only if your transistor technology is not GTO). If the overhead supply voltage is AC, which will almost certainly be just one phase, then it must be converted to DC first. This step is not required if your overhead supply voltage is already DC or if you have a third rail supply.
@@ajgyt3347 originally, the Class 323 had HOLEC 2-level GTO-VVVF, then the VVVF was renewed to Alstom and the GTO thyristors were replaced with IGBT's, but the modulation pattern and inverter programming remained the same so the sound was mostly unchanged. The JR 209 series do not use the exact same electronics; they originally had Mitsubishi 3-level GTO-VVVF.
So many gear changes. You can even hear it short-shifting a bit at 0:32! Just having fun. It is the variable frequency traction inverters. The gear changing like sound is actually the inverters changing the rate of pulsing of the transistors. This is needed so that power is not drastically reduced and the transistors do not overwork or overheat. Similar to how a car needs to change gear to not let the engine lose too much power and spin at a higher RPM than required and overheat.
Well in TSW3, they actually didn't do too bad of a job. Just that the sounds don't get to the point of going ridiculously high pitched like they do in real life. Would be nice to have better run sounds at speed, too.
Aston railway station has a speed restriction of 20mph, and the drivers of these trains can't apply too much power at once as to avoid wheelspin and concern to the passengers. Put that thing straight into notch 4 without considering that and yes, it will go like a rocket.
I honestly don’t like the sound on the 3 car class 323s. They are likely to survive with the operator West Midlands Railway 🚃 until the very severe delayed date around perhaps 🤔 Tuesday 31st December 2024 at the latest. 26 of the class 323s are in the Midlands where 17 will go to Northern Rail and 9 others could be perhaps 🤔 go to ScotRail or not to be used at all. Made in 1992. Class 323s conveys a toilet 🚽 and standard class accommodation only. I’m sure they are good 👍 trains 🚆. 🙂
This train sounds like its shifting gears
Because It's Motors are Actually GTO Thyristor Controlled, Like In Japan's 209 Series.
I’ll be honest it kinda does tho
Have you heard the dutch virm train? Cause you need to hear it
@@gewoonandy8755 yeah, ive heard the VIRM
The swedish trains X60/X61/X62 also sound like theyre shifting
Like an F1 car
My favourite train. The 323s have such a great sound.

Why is it so much louder than the Japanese 209 that uses the same technology?

ok
I learn something new everyday. Thanks
Class 323’s r one of my favourite trains ever. The motor is most of my fav bit. As always! ❤
My favourite EMU, sound great and go like a rocket 🚀
These sound exactly like the trams in Amsterdam or the Dutch railways SM '90.
Of ze virm doedelzak
Awesome sound. Great video
323 motors are amazing
I've always loved the way these traction motors
The Helsinki metro M100 train makes similar sounds.
i miss these now
Amazing it sounds like a 96 tube stock lol
That's what I was thinking, the Jubilee line stock 👍
Reminds me of the old midlands metro
fantastic shot there mate especially seeing the class 323s at aston going to redditch

Its the closest to a brush 465 :D
Originally BRELs sounded great
I am curious how DTG will mess up the sound this time

I was expecting a motor sound similar to some of the 466s/465s.
Edit: Forgot to say the 465s with ORIGINAL motors.
All Class 465s have their original motors.
@@bfapple I should say original Alstom motors
@@williamhuang8309 no need to specify - all 465s have the original motors. It’s just the electronics that was changed on the BREL/ABB units.
@@bfapple or rather, the VF drives found on the Metro Cammell units. It's just that people call them Alstom motors.
@@williamhuang8309 the sound is caused by the three phase inverters. Doesn’t need a fancy name.
This is the brel brush 465s crazy cousin lmao
CAN'T BEAT THE CLASS 323S
I am getting a sense of
F1, Space ship, Class 365 (from south eastern)
Now, that's the classic mistake I make called pressing the wrong key next to the correct key. Seeing it as a 3 but still reading it as a 4.
So good I can't stop replying
We have the same mother here at Japan.
Our ktm komuter has similar to these sounds too but the train is retired now.
Class 323 🤝 INKA EA101 BN-Holec
Sounds like a dutch NS VIRM
Closest to a brush 466/465 you can get these days.
What was the clicking sound at the beginning?
Everytime I hear the sound reminds me of a F1 car 😂😂
It sounds like a spaceship
0:27
almost like the NS Virm or the qld rail IMU/SMU
They had something like this on the class 465
I think we may have topped the jubilee line sound
sounds like the dutch NS VIRM train
Sounds as if someone is getting abducted by aliens in some 1980s film.
That is available on Northern Trains
sounds like an Amsterdam 11/12G tram go look it up! very similar!
Lol Peppa pig on the window
Sounds similar to the KTM Class 81 in Malaysia until they change traction motors recently
KTM Class 81 and this thing are basically the same with a few minor changes
my favoiurite train used to be the 142. i learned its trash and now i love the class 150 both class 150/1 and class 150/2
Not much better lol
なるほど確かに日本の209系と似ている
0:33 Sounds a bit like the class 465 traction motor
I call it the Class 323 Hyper Networker
@Aquaopter Lots of folk refer to it as a Hyper Networker although they share sod all with Networkers
Sounds a bit like the Chinese-made rolling stock used in MTR south Island line
Slow acceleration 😭. I thought they had a acceleration that would give Sonic a run slower than the likes of the 323
Actually they have a good acceleration, in this case the train was heading towards a set of points at reduced speed.
@@InterRegios Ah. So that's why the driver used notch 1, and not 4.
Aston railway station has a speed restriction of 20mph, and the drivers of these trains can't apply too much power at once as to avoid wheelspin and concern to the passengers. Put that thing straight into notch 4 without considering that and yes, it will go like a rocket.
The train sounds like a Formula 1 car toned down
this sounds like a NS IRM
Sounds like Mitsubishi GTO
Is anybody gonna talk about Peppa and George at the 2nd window?
0:31 IS THAT FUCKING PEPPA PIG ON A TRAIN?!
WHAT THE HECK?! 😂😂😂
lol?
@@leaflaneleft theres literally peppa pig on that train
@@phheonnixx yes ik
why was it accelerating slow
It's because the throttle stick wasn't fully up.
209系と南海2000系を足して2で割ったような音
Train sounds line JR 209 Series
Sounds like a formula car😂😂😂😂😂😂😂
NS DD-IRM, JR East 209
If only america had these :(
I wonder what these would look like in Amtrak livery? 🤔
I wish that the 365s could run in America, too.
@awesometrainsandbuses694 God no, that'd be the equivalent of thinking about an InterCity Executive Class 153
These trains don't have nice motors sounds at all, they have the best motor sounds ever!
In 8th gear i heard MLR noise
this is not using the rail of thirdness
No it's using the spicy pixie cables
it sounds like an F1 car
Perfect Peppa pig front
It kinda sounds like an alarm
Very similar to the NS VIRM if I say so.
Sounds like a ns irm
Brrrrrrrrr
It was great to see Peppa pig!
Peppa Pig on the window lol!

It has peppa pig on the front 💀💀💀💀
I sound likes F1 v10
lol, the sound is the same as krl holec train
Memang satu pabrikan propulsi...
sound countries:
🇬🇧 🇯🇵 🇳🇱 🇭🇰
LOL!!! Peppa pig on a train!
This train.have 9gears
no, that ain't gears. the train is thyristor controlled.
And did you notice peppa pig on board
Peppa pig... How has no one noticed it
Because it's just an ad.
disabled 465
I can see Peppa Pig and George Pig.
Probably from an advertising livery
Tbh i hate this sound. Idk why everyone thinks that it’s „magic”
kinda sounds like a 465 on drugs
Why is there Peppa Pig on the side?
It's an advert.
Ugly train, good sounds
F1 car
