China-Europe Express refers to container freight trains that travel between Chongqing, Chengdu, Zhengzhou and other cities in China, and Europe and many countries along the “Belt and Road”. As an important logistics channel for Sichuan to integrate into the “Belt and Road”, there are more than 2,000 China-Europe trains operating from Chengdu every year, connecting 67 overseas city stations. Compared with sea freight, the most obvious advantage of railway freight is the short time. After the optimization of the train operation by the countries along the route, it only takes 10-15 one-way. The shipping takes 40-50 days, which still does not consider the time from the place of manufacture to the port. The shortened logistics time means that funds can be withdrawn in advance and the capital turnover rate can be increased. This is what companies are happy to see.
