R211 propulsion observation

[texassubwayfan555]

So I was watching videos of various Indian metro systems when I came across this video of the Chennai Metro: https://www.youtube.com/watch?v=LRt08SBJgYo

The Alstom Optonix propulsion is exactly the same! And the kicker is these trains started construction in 2010 and entered service back in 2014.

For reference here is a video of the r211: https://www.youtube.com/watch?v=y4y_sCEJ9IA

I cant be the only person that has noticed this?

Your second paragraph, are you trying to imply the R211s propulsion is outdated? I recall watching one of DJ Hammers YouTube vids of the R211 testing and remember the description said they had to install updated mechanical gear on the cars.

No. I just thought it was cool that the same propulsion can be found on a totally different system.

I was not sure if it belonged there or in its own thread. Sorry, I am still new to the forum

In the Atlanta Subway, some of the cars have the same propulsion as the R142A/188 and R143s.

Too bad they wont be around for much longer, as MARTA is replace all their trains.

I have also noticed that the propulsion on the MTR "A" trains (Adtranz–CAF EMU) sounds like a low pitch version of the R142A/188 and R143 propulsion.
