According to the traffic situation in Sichuan, especially Tongjiang, which you mentioned, it will be impossible to connect trains in the next five years. Then, according to the economic development of Bazhong, our dominant city, and the gradual formation of the transportation network, the 11th Bureau of China Railway officially started construction of Dayu Railway in June 5438+February, 2007, which will pass through Bazhong. At present, the Pakistan-China railway construction project has been officially undertaken by the Second Branch of China Railway 11th Bureau, and it is expected to be completed in May 20 10. It may take half a year for the later construction project to be fully opened to traffic. If you want to go from Xi 'an, Shaanxi to Chongqing, it depends on the design of the chief commander and chief engineer of railway engineering. If he is quick-witted and quick-witted, he will say that Tongjiang will take the highway and then Tongjiang will take the train. That may be many years later! I hope it helps you!
