[1] Trains on Line 14 reach a maximum service speed of 120 km/h (75 mph),[2] allowing for passengers to travel from outer Guangzhou to the city center in one hour.

Line 14 actually consists of two independent services - a mainline which opened on December 28, 2018, connecting Jiahewanggang in Baiyun to Dongfeng in Conghua and a shuttle branch referred to as the Knowledge City Line, which runs from Xinhe in Baiyun to Zhenlong in Huangpu.

After Taihe, it continued southward, passing through Jiahe and Xinshi, ultimately terminating at Guangzhou Railway Station.

The line was split in two phases for construction with Jiahewanggang as the dividing point, both of which were submitted for approval and built separately.

Xinguangcong Road was fully open to traffic in June 2021, four years after completion of Line 14.

The second phase of Line 14 extends the mainline south to Guangzhou Railway Station from Jiahewanggang.

The electrical substation at Baiyun Cultural Square will be expanded to meet the necessary power requirements.

[7] On June 30, 2019, the first tunnel boring machine departed south from the Jiahewanggang Station construction site.

These plans include a southeastern extension from Zhenlong down past Xinsha on line 13 and crossing the Dongjiang river into Dongguan.
