Analysis and Capacity Expansion Revamping of Passenger-Cargo Transportation in the Chengdu-Kunming Railway

The Chengkun depot in the Chengdu-Kunming railway has some problems because of poor transportation capacity, such as low traveling speed of passenger-cargo train, bad transportation organization elasticity, limited passenger transportation, and insufficient cargo transportation capacity. After predicting and analyzing the future demand of passenger-cargo transportation, a conclusion has been drawn that the transportation capacity of the Chengdu-Kunming Railway Line is far from meeting the economic development along the line's demands at present, and must expand transformation capacity. Different revamping measures were compared, and some of those measures are accelerating to built strategy loading point and expand the capacity of the existing lines so as to alleviate the pressure of transportation capacity, but, building the second line (or double track) is the basic scheme of solving the capacity problem.
