Sichuan Basin
Together with the Hankou–Yichang and Yichang–Lichuan sections of the Huhanrong mainline, the Chongqing–Lichuan line forms what was, until the completion of the Xi'an–Chengdu high-speed railway, the only high-speed rail connection between the Sichuan Basin and the rest of China. It carries numerous high-speed trains running between the cities of the Sichuan Basin (Chengdu and Chongqing) and various destinations in the central and eastern China.
