On September 23,2018,the Hong Kong section of the Guangzhou-Shenzhen-Hong Kong High-speed Railway was open to traffic.Hong Kong has entered a high-speed rail era.After the excitement,there were readers who called to inquire:"Is the Guangzhou-Shenzhen-Hong Kong railway a high-speed railway,or an intercity railway?"The author replied that"It is both a high-speed railway and an intercity railway.As seen from the location attribute,it belongs to an intercity railway in the Guangdong-Hong Kong-Macao Greater Bay Area,and seen from the speed attribute,it is a high-speed railway.It is the end of the national high-speed railway network."
