The Nanning–Guangzhou high-speed railway (Chinese: 南宁至广州铁路; pinyin: Nánníng zhì Guǎngzhōu Tiělù),^[1] abbreviated as Nan–Guang railway (Chinese: 南广铁路; pinyin: Nán–Guǎng Tiělù), connects Nanning, capital of Guangxi Zhuang Autonomous Region, and Guangzhou, capital of Guangdong Province, in China. Construction started on November 9, 2008; Nanning to Wuzhou was completed by April 18, 2014, while the full route opened on December 26, 2014. The total cost was about 41 billion RMB.^[2] The railway is expected to spur economic development, and increase mobility across the Guangxi and western Guangdong regions.

Route

The railway travels mostly along the Pearl River Delta's Xi River valley. From Nanning it initially follows the route of the Liuzhou–Nanning Intercity Railway to Litang in Binyang County. It then heads eastward through Guigang, crossing the Yu River, over Guiping, Pingnan and Tengxian to Wuzhou. After entering Guangdong it passes Yunan and Yunfu to Zhaoqing, before reaching Guangzhou South railway station. Its total length is 576 km (358 mi), 349 km (217 mi) of which is in Guangxi, 227 km (141 mi) in Guangdong. Twenty-three stations will be built along the route, though not all will service passengers.

Future development

Rail Transport in Nanning

Nanning is already connected by conventional-speed rail to Vietnam, though Pingxiang on the China–Vietnam border. Nanning–Pingxiang high-speed railway is also under construction. This would allow high-speed trains from Guangzhou to Nanning to continue on to Vietnam and other countries in ASEAN, connecting with the Kunming–Singapore railway.^[9]
