Siemens - Taurus nice starting sound train 4K

Siemens Taurus locomotive with a passenger train in the main station of Wien (Hauptbahnhof). You can hear the sound do-re-mi-fa-sol when the locomotive starts.
I read all the comments, Sub and comment for more. Thanks to all. ;)

The engineers at Siemens are just showin' off now.

What kind of instrument do you play?
Me: Locomotive

[marin]

Austria is a big country for music. Even trains can play.

[voyagerslav]

Holy damn... When I was playing that train on simulator, I thought that developers were too lazy to add real like sound effects... But this is the real sound???

[CmdData]

Even though this locomotive is already 20+ years old it's probably still one of my favorites. The musical acceleration, the speed it can achieve, it's versatility and its sleek modern design that's absolutely timeless. A+ job Siemens.

The sound is not just accidental! It happens because the electronics convert the incoming power to a specific frequency to drive the motors when accelerating, which then make a sound.
It could have been any sequence of notes, but they chose this one because it sounds pleasant :)

Even the brakes sound nice when they release. Hearing those IGBT's singing, sounds so much more natural than the class 353, which makes a weird screaming noise when they move away.

[juanzingarello]

Wait. That was the train making that stepping sound?? I was thinking in my head "Man I wish that saxophone player would shut the hell up so I can listen to the train."

[diegoarpino]

In case anybody is wondering, that is a G mixolydian scale, or basically a G major scale but the F# is natural.

[drinkingwater]

I am in Austria and hear this sound everyday. Twice.

[オラハハハ]

The sound of this Siemens inverter is like a sound of a violin, but the sound of Siemens inverter of Keikyu Train in Japan is more comfortable. This is absolute.

[Crock]

Btw, for those out of the loop, that’s not an artificial sound made by some speakers on the loco. That’s the sound the electrical motors in the trucks make. Each sound level corresponds with a “notch” on the throttle.

According to wikipedia: "When switching on from a standing position, a noise can be heard that is reminiscent of playing through a scale on a tenor saxophone . It is created in the three-phase motors by activating the converters . The noise is twice the clock frequency of the pulse- controlled inverter, which is increased in stages.

The frequency changes in whole and semitone steps over two octaves from d to d ″ in the tone stock of the main tones . It is a Doric scale on the root note D.

This makes it possible that when the wheel sets are thrown (for example due to wet rails) a four-part start-up tone is produced". But I hear it starts from note G: 0:14

Do you want to have a locomotive or a musical instrument?
Siemens: YES

[laurenceegan]

I must confess: I looked round for the saxophonist playing scales the first time I heard this on a visit to Berlin.

And the second time. And third time...

[abloogywoogywoo]

It was time for Thomas to leave.
He had listened to everything.

[StaK_]

Damn, that is a _clean_ train!
Also, love that Do re mi :-)

[w.cooksy]

The last time I heard anything so musically impressive must've been when Japan had Siemens AC systems on their Keikyu N1000 units. Man, it sounded like a symphony when those things started up. :)

[hermankoerts]

I hope this gives some clarifcation: The overhead line voltage is rectified into Direct Current (DC). Between the DC stage and the traction motor is an inverter. This inverter feeds the traction motor with a pulse-shaped voltage. This is because the power-semiconductors in the DC to AC inverter can only change between conducting and not-conducting (on or off). By applying pulse-width modulation to the on/off state of the semiconductors, voltages are simulated that result in a traction-motor current as if the motor was connected to a "normal" three phase AC supply from a grid. It is true that the rotational speed of the motor is determined by the (simulated) frequency of the supply voltage/current. During the acceleration, not only the frequency of the voltage has to change, but also the magnitude. (This is to keep the magnetic fieldstrength in the motor roughly constant). This is also done by modifying the pulse-pattern. All this "modulated-pulsing" can result in the sounds like in this video. :-) In recent years big advancements in power-semiconductor technology were made: from the thyristor, to the Gate turn-off thyristor, to the IGBT. The advantage of this all is that the robust three-phase AC induction motor can be used, instead of a motor with a commutator and a complicated armature winding.

Same here in Mumbai. Some rakes of suburban trains are made of Siemens, they also produce the same sound but a little deep
