If you think that the traffic on the street outside your apartment window is noisy, stop complaining now. You've got nothing on the residents of this Chongqing apartment building: they have to deal with a train running straight through the structure!
"Our city is very heavily built upon and that can make finding room for roads and railway lines a real challenge," a Chongqing Rail Transit Group spokesperson said in 2014 as reported by Oddity Central, "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. In a city as fast paced as this it was clear people wanted to get around quickly. Extending the railway line this way was a gamble, but it was one that paid off."
Interestingly, having a train traveling straight through the building several times a day did not reduce property values. In fact, it actually made the apartments more expensive as it made access to public transportation much more convenient for the dwellers.
