A video showing a monorail in southwest China’s Chongqing automatically switching tracks has gone viral again during the National Day holiday.⁣ ⁣ As the train speeds toward the junction, a massive section of track slides into position, allowing the train to seamlessly switch tracks, with no manual intervention.⁣ ⁣ The system is part of Chongqing’s monorail network, designed to navigate the city’s mountainous terrain, steep slopes and rivers.⁣ ⁣ At the Biji Station on Line 3, the sliding turnout can move a section of track weighing about 120 tonnes by 4.25 meters, with an alignment error of no more than 3 millimeters. The switching process takes less than 30 seconds.⁣ ⁣ For passengers, it’s not just a ride, but also a front-row view of some seriously impressive rail engineering.⁣ ⁣ #Chongqing #ChinaMoments #nationalday #holiday #ChinaTravel
