This special railway tracks takes riders into a tunnel that was built through a block of apartments in southwest China’s city of Chongqing.
To take a ride in this train, the residents just have to step outside their apartments and hop on at the Liziba Station ,located on the sixth to eighth floors of the building.
The smoke-free light rail system, which has a low noise and vibration features, is famous for being of one the quietest rail lines in China. The sound of the train was designed to be only as loud as what you’d hear from a dishwasher -meaning it is very quiet.
This way, the planners were able to integrate the rail systems into the already congested city without having to demolish the 19 Storey residential building.
