积极加大列车密度不断扩大运输能力

Increasing Train Operation Density Actively and En larging Transport Capacity Continuously

分析了我国铁路的负荷情况，回顾了加大列车密度在提高铁路运输能力中的地位和作用。提出为完成２０００年的运输任务，今后在大力增加列车牵引重量的同时，还应积极加大列车密度。分析了单线和双线区段所能达到的能力。提出今后主要应从提高复线率和自动闭塞的比重，来加大全路平均列车密度。

The paper expounds the transporta tion load of China railways, and reviewed the position and role of increasing train operation density in raising transport capacity. The paper hence suggested that to achieve transportation task for year 2000, China rail way should actively increase in train density while rais ing traction load of trains. The paper also analyzed the capacities which could be reached of single-track and double-track sections, and proposed that the average train density should be increased by way of raising the percentages of double-track and automatic blocking.
