大力发展电力牵引 提高铁路运输能力

To enhance the railway transportation capacity by promoting electric traction

对电力机车和内燃机车牵引性能进行比较，并以郑州铁路局解决运能与运量矛盾的具体实践为例进行说明，从而提出提高铁路运输能力的主要措施是大力发展电力牵引。

Comparisons are made regarding traction performances between electric and diesel locomotives.The practice of Zhengzhou Railway Administration in resolving the contradiction between the traffic volume and carrying capacity is cited to prove that a efficient way to enhance the railway carrying capacity is to promote electric traction.
