The positive line of the Ya'an end interval.

The main line from Tianfu to Chaoyang Lake Station is 80.6 kilometers; the connecting line to Puxing Station of Chengdu-Kunming Railway is 10.1 kilometers, and the connecting line to Chengdu-Kunming Railway to Kunming is 3.4 kilometers; it is planned to adopt the standard of National Railway Class I, double-track and 160 kilometers per hour (The speed of 200 kilometers per hour is reserved for the plane); There are 5 stations along the line: Tianfu, Xinjinnan, Shou'an, Pujiang, and Chaoyang Lake.
