Watch: In China, trains pass right through a 19-storey engineering marvel

Nestled in the heart of China lies the bustling city of Chongqing. Its sprawling metropolis is home to over 30 million residents, making it one of the largest cities in the world. But amidst the skyscrapers and crowds, there's a unique attraction that's been turning heads - the Chongqing Rail Transit.

This isn't your average transit system. Trains don't simply glide along tracks above or below ground. Instead, they pass straight through the middle of a 19-storey residential building, known as the Liziba monorail station. It's a feat of engineering that's captured the attention of people around the world, with a viral video showcasing the incredible sight of a train coming through a residential apartment block.

The monorail station is located between the sixth and eighth floors of the building, and its innovative design has saved valuable space in the densely populated city. Passengers can hop on and off the train right in the middle of a residential building, surrounded by apartments and offices.

But it's not just a convenient way to get around. The Chongqing Rail Transit has become a symbol of China's ambition and engineering prowess. The country has long been known for its impressive infrastructure projects, and this is no exception.

Of course, with any ambitious project, there have been concerns. Some worry about the safety of living in such close proximity to a train track, while others wonder about the impact on property values. But for many residents, the Chongqing Rail Transit has become a point of pride for the city.

As China continues to grow and innovate, it's likely we'll see even more impressive feats of engineering in the years to come. But for now, the Chongqing Rail Transit stands as a testament to what's possible when ambition meets ingenuity.
