Very very nice! The sound of Velaro BR403 is always so cool ;-D

[@TuukkaVarjoranta]

***** As far as I know this older ICE3 is also part of the "Velaro" product family.

[@TuukkaVarjoranta]

***** :-)

+Tuukka Varjoranta +Gerhard RW In fact, ICE 3 is just the BASE of Velaro. The first Velaro is the Class 103 for RENFE.

​@@SepianSound does that mean the DB class 403 ICE 3 is the original and first train before it was made for other countries etc.?

[@SepianSound]

@@Myron0117 Right.

[@jurisworld181]

Ey was machen du hier😂

[@noctivagusexploris300]

Very nice sound! Reminds me of my last trip with ICE 611. The sound quality is really good! What kind of microphone are you using?

[@SepianSound]

Many thanks! My microphone is the AT9901 from Audio-technica. It's small and has clip. It's easy to record for a long time.

[@noctivagusexploris300]

Thank you!

So the switch in sound as the train is starting up is the inverter changing the frequency of the three phase AC output to the asynchronous motor driving the train, right?

[@velarod3961]

What switch in sound are you referring to? Dobyou mean the change of the carrier frequency or the switch from carrier-based PWM to SHEPWM?

[@tractioninverter]

​@@velarod3961 Der synchrone teil ist nicht immer "SHEPWM" - es gibt auch andere harmonisch optimierte Pulsverfahren, wo die Pulsmuster mit der Sinusfrequenz synchron sind. Siemens nutzt beispielsweise auch die "Mittenpulstaktung". :) Die folgenden Bücher zu dem Thema Antriebstechnik sind äußerst interessant und ich empfehle sie sehr!

Gänsehaut!!! Goosebumps!!!

0:50あたり少し堕落が入ってますね。 にしてもいい音（＾_＾）

[@velarod3961]

What you can hear at 0:50 is a high-speed track switch, commonly used on the SFS Köln-Rhein/Main. The sound you can hear is normal and no corruption or anything like that.

[@bigtrainguythore]

What coach was this recorded in?

[@rinkito2002]

cool
