As consecutive sections of the Beijing–Guangzhou high-speed railway became operational, the railway authorities shifted much of passenger traffic from the original railway to the new high-speed line. This allowed an increase in the amount of freight volume transported over the original route. For example, according to preliminary estimates, after the entire Beijing–Guangzhou high-speed railway opens, the annual freight capacity of the northern half of the Beijing–Guangzhou railway (between its two main freight stations, Beijing's Fengtai West Station and Wuhan North railway station) would increase by 20 million tons.
