texassubwayfan555 Posted August 23, 2022 Share #1 Posted August 23, 2022 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? 0 Quote Link to comment Share on other sites More sharing options...

trainfan22 Posted August 23, 2022 Share #3 Posted August 23, 2022 Your second paragraph, are you trying to imply the R211s propulsion is outdated?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. 0 Quote Link to comment Share on other sites More sharing options...

No. I just thought it was cool that the same propulsion can be found on a totally different system. 1 hour ago, Railfanner Mario said: U do realize there’s a “R211 discussion” thread for a reason brother man I was not sure if it belonged there or in its own thread. Sorry, I am still new to the forum 0 Quote Link to comment Share on other sites More sharing options...

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. 0 Quote Link to comment Share on other sites More sharing options...
texassubwayfan555 Posted August 24, 2022 Author Share #6 Posted August 24, 2022 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. Example: https://www.youtube.com/watch?v=2Xr8WH38-N4 (Sorry I can't find a video with better audio.) 0 Quote Link to comment Share on other sites More sharing options...
