Is there a through train from Dujiangyan to Zigong Rongxian? If not, which station is crowded and take the expressway to Chengdu?

The main expressway from Chengbei Passenger Transport Center to Rongxian County is Le Cheng Expressway, with a price of 70. Liangjiaxiang takes Zigong and turns to Rong County and Chengdu-Chongqing Expressway. The fare is more than 80 yuan, almost 100 after the transfer, and the time is longer. I usually take a bus to Rongxian at Chengbei Passenger Transport Center. I suggest you take a bus at Chengbei Passenger Transport Center. Dujiangyan takes more than 20 minutes by train. Chengbei Passenger Transport Center is 500 meters west of North Railway Station.
