Hear the Alstom's traction sound from South Island Line C-Trains (Arrival and Departure) 

True

That’s what I thought! It sounds like R211

True

@@unitedrail-mainchannel8991 same propulsion : Alstom OptoniX IGBT VVVF

More like Buenos Aires metro Line H

what????

It’s half Siemens

@@kevinmontes9933 the sound resembles the settings that Siemens uses, but it is not specific to Siemens. Alstom has been making adjustments with steps for a long time. Seoul metro 7000/8000 series, MF88, 1996 stock, BB37000, R211. The future RER NG in Paris will also have a similar sound but it's OniX IGBT VVVF

Yep

Really? Where did you get that?
