Guangqing Intercity Railway is the first intercity railway constructed and operated by Guangdong Province. It starts from Huadu Station, runs through Letong Station, Shiling Station, Yinzhan Station and Longtangzhen Station, and ends at Qingcheng Station, with a total length of 38.1 km and design speed of 200 km/h. Xinbaiguang Intercity Railway starts from the north end of Huadu Station of Guangqing Intercity Railway, and sets three stations: Huachengjie Station, Huashanzhen Station and Airport T2 Station, with a total length of 20.131 km and design speed of 160 km/h. Trains of both railways adopt CTCS-2+ATO mode, which combines the advantages of both high-speed railway and metro, and could effectively fit the operation of intercity railways, featuring high speed, high density, short intervals between stations and public transportation operation.
