Incredible! Train travels right through hole in 19-storey block of flats

A light railway track has been built to go through a hole in a residential 19-storey building in China. The city of Chongqing in the south-east of the country has a population of 49 million packed into 31,000 square miles, causing urban planners to look creatively at solving space issues. A special railway station was built into the block of houses, set into the sixth to eighth floors. Even though they are living in close quarters to a busy train station, any noise has been muffled by special equipment.
