With 5G signals(信号 xìnhào), wireless charging(无线充电 wúxiàn chōngdiàn) and intelligent lighting, the smart train G8811 departed from Beijing North Railway Station at around 8:30 am to Zhangjiakou in North China's Hebei province.

The railway is 174 km long, with 10 stations along the line.

With a maximum design speed of 350 kph, it will reduce(减少 jiǎnshǎo) the travel time between Beijing and Zhangjiakou from over three hours to 47 minutes, facilitating inter-city traffic and crucial for the co-host of the 2022 Beijing Winter Olympics.

Chongli railway, a branch line(支线 zhīxiàn) of the Beijing-Zhangjiakou high-speed railway, also went into service Monday. It is 53 km long, with a maximum design speed of 250 kph.

Construction of the Beijing-Zhangjiakou high-speed railway began in the first half of 2016. The railway underwent test runs earlier this month.
