襄渝线再扩能问题探讨

Exploration of Re Enlarging Capacity of Xang Yu Raihay

襄渝线虽经过扩建，但１９９６年线路通过能力已近饱和，随着国民经济发展，进出四川的物资将会有很大增长，为提高襄渝线襄樊北至胡家营段的通过能力，可采取更换机车型号，提高货物列车牵引重量；在困难区间修建双线插入段和采用定点计轴自动闭塞三种办法。三种办法互相不制约，可单独使用，也可综合使用，但不论采用何种方式都要同时增加部分中间站的到发线和加强供电能力。

Although the Xiang Yu Raiway has been reconstructed,its traffic capacity has nearly reached saturation by 1996.With national economic development,the goods and materials going in and out of Sichuan will increase greatly. In order to raise the traffic capacity of the section between Xiangfan North and Hujiangying on Xiangyu Railway,the following three methods can be appplied:changing locomotive model,increasing traction tonnage of freight trains,and building double track inserting section in difficult sections and applying automatic blocking by counting axles at fixed points. These three methods do not restrict each other and can either be used alone or comprehensively.However,no matter which method isused,the receiving track should be increased in some interim stations and power supply should be strengthened simultaneously.
