Beijing, Ta. 04 February 2022 Friday

With the 2022 Beijing Winter Olympics, the world’s first self-driving high-speed train is already in operation, carrying athletes and officials between two major cities, the historic Beijing-Zhangjiakou Intercity Railway.

Built in 2019, the station is within walking distance of the entrance to Bedling, the most popular compartment of the centuries-old wall. The railway line and its attached station were dug deep underground to prevent structural damage to the iconic monument.

The three-storey structure, with a depth of 102 meters below ground and covering an area of ​​more than 36000 square meters, is said to be the world’s deepest and largest underground high-speed railway station.

The construction of such a complex station, which includes a 12 km long tunnel system, is a UNESCO World Heritage Site. No easy feat.

According to Chinese state media, engineers used an electronic detonator to detonate the explosives for up to a millisecond. This was the first time the technology was used in China and allowed workers to make vibration velocities of less than 0.2 centimeters per second.
