LIRR Kawasaki M9 EMU MELCO AC Traction Motor IGBT-VVVF Inverter HQ Sound Recording (9/16/19)

[@Texas80]

I was wondering why the trains weren't moving .... I'm high.

[@jeremyzorek]

Sounds fantastic!

[@RonDevito]

I was wondering what that high-pitched sound was on all the recent subway cars and these M9s.

[@camjkerman]

That's an IGBT taction inverter system. We have them everywhere here in the UK and Europe. First came about in the mid to late 90s and they generally have a solid tone at the start. A favourite of mine is the Bombardier Electrostar, rather the typical modern British commuter train.

😍😍😍

Reminds me somewhat of the r179s

[@lol-ug2ry]

Nice

[@camjkerman]

Why are so many American trains mostly unpainted metal. It's not a good look. Especially from a British perspective where all our trains are completely covered in the livery. And the tiny windows as well. They must be horribly dark.

[@Dislynn]

We like our trains that way

[@goose3303]

On the contrary, the trains are very well lit, and the unpainted metal gives a sleek look, while being "graffiti-proof"

[@CentralJerseyRailfan]

camjkerman I somewhat disagree, for example the Yamamote Line E235s in Japan are unpainted metal but look hot

[@MessyPointedBlob]

Are you volunteering to pay for the constant repaints the train cars will need due to graffiti and general wear and tear damage?

[@acegarr22]

The M9s came with tinted windows for sun glare. And trust me you can clearly see whats outside.
