Planners in China had a task at hand to construct a new railway line in a congested residential area and they unveiled a complete ingenious plan by laying a track that runs through a building.

The astonishing train line runs right through the middle of the building in Chongqing, known as Mountain City for its countless skyscrapers, and is one of the most heavily populated areas in China with nearly 33 million people.

The idea behind monorail running through a building was conceived in view of burgeoning population in the city.

But instead of blighting residents’ lives with the sounds of trains passing through, planners claim the train line has increased the value of the apartments because it is so convenient for transport links.

According to them, the trains produce just 60 decibels of noise as it passes through the building — about at loud as a dishwasher.

City transport spokesman Yuan Cheng in an interview said: ‘Our city is very heavily built upon and that can make finding room for roads and railway lines a real challenge.

‘Sometimes there just isn’t room on the ground so we have to think about going under, or over, or – in this case – straight through.
