Some informations o nthe sound... The high-pitched two-frequency (2-tone) sound that we hear is the asynchronous PWM that remains up to 90km/h (or "from", during decellerations), and only then we switch to synchronous pattern. This is the Alstom Palix IGBT-VVVF (a derivative of the OniX).

I love seeing this. I hope their able to enter service without any additional delays.

[@OutdoorsSC]

Wow, that is nice. I think our Amtrak that stops in Clemson is from the 1960's. They sound electric...

[@JamesGJGSUSHI]

[@Lodai974]

yes ,all TGV locomotive built after the 2xx series (the 47xx ,7xx to 9xx) use same inverters modulation and same motors.

Just wondering why US trains can never make the profile of the loco line up with the carriages or vica versa

[@FanRailer]

This specific instance is by design, so that when tilting, the coaches don’t exceed the clearance envelope of the power cars, which do not tilt.

[@ChrisWheatley-s2k]

@@FanRailer I didn’t realise the coaches tilted but the locos didn’t, thanks for explaining that

[@randomtransitadventures]

Old acela sets are better
