China’s Fuxing, dubbed as the world’s fastest commercial bullet train, started operations in the Beijing-Tianjin-Hebei region on Monday.
According to manufacturer China Railway Corporation, the next-generation trains run at 350 kilometers per hour (217 mph), with top speeds hitting the 400-kilometer (249-mile) mark.
The trains, running on the Beijing-Shanghai line from September 21, are expected to cut travel time between the cities — a distance of 1,318 kilometers (819 miles) — from six to just 4.5 hours, making seven round trips a day.
The route between Beijing and Shanghai is reportedly among the most used high-speed railways, with some 600 million commuters riding since 2011.
It was also noted to be the most profitable, reportedly earning 6.6 billion yuan (about $1 billion) in profits in 2015.
As per People’s Daily, China began running trains at 350 km/h in August 2008. At least three more lines of similar speeds were launched subsequently, until the government required slowdowns between 250 and 300 km/h (155 and 186 mph) following a deadly accident in Zhejiang Province in 2011.
At 22,000 kilometers (13,670 miles), China owns the world’s longest high-speed rail network, roughly 60% of the global total. The government aims to further the distance at 30,000 kilometers (18,641 miles) by 2020.
