CAF NS-07 - Santiago Metro - Line 1 - Entire Course 

The most demanded line of Santiago's network, under stress all the day. This is the entire course between stations Los Dominicos and San Pablo. Enjoy the interesting sound of this train, similar to the NS93.
The NS07 trains initially doesn't feature air conditioning, but after 2012, it featured that in order to improve travel comfort in trains that goes crowded all the day.
Recordings made in May 2019.
