History
Guangdong officials listed the Ganzhou–Shenzhen HSR as a major part of the province's 2011 agenda, and Shenzhen Mayor Xu Qin called for accelerated construction of the line at the provincial legislature's annual session in 2012. Peng Jianwen, mayor of the city of Heyuan in northwestern Guangdong, confirmed in January 2014 that construction of the Ganzhou-Shenzhen HSR will start in 2015 and be completed in 2020.

Construction on the 10.24 km long Longnan tunnel, the longest on the railway, began in April 2017.

Tracklaying began on 1 February 2021.
