The Beijing-Shanghai high-speed railway line, which started construction three years ago, will run trials for 10 days from June 9 to June 19 of this year, the Yangtze Evening Post reported.

An ID-based ticket booking system will be used for all China Railway High-Speed (CRH) trains starting June 1 in an attempt to prevent ticket scalping. Shanghai may implement the system as early as May 22, due to its 11-day presale of tickets.

During the Beijing-Shanghai line’s trial, scheduling of other Beijing-Shanghai trains may see some adjustments. But even train attendants who are going to serve on the Beijing-Shanghai CRH trains know little about its speed and passenger capacity.

China's high-speed rail network has been developing rapidly over the past decade, reaching a total of 8,358 kilometres, the world's longest.
