要提高铁路运输能力,其关键在于牵引动力现代化,而对铁路牵引动力的改造,又是实现铁路现代化的中心环节。本文从各种牵引动力的燃料消耗比较,经济有利范围,以及在不同线路上的运量适应范围,说明电力牵引大有潜力可挖,虽然它比内燃牵引和蒸汽牵引一次投资大,但由于运量大,取得的利润多,可以迅速回收。同时指出,在旧线的电气化改造方面,还须注意协调配套问题。
The key to improving the capacity of railway transportation lies in the modernization of the traction power. The transformation of traction power of the railway is also the central link in the modernization of the railway. This paper from a variety of traction power fuel consumption, the economy is advantageous range, as well as in different lines of traffic adaptation range, indicating that electric traction has great potential to dig, although it is a big investment than internal combustion and steam traction, but due to transport Large amount of profits made, you can quickly recover. Also pointed out that in the electrification of the old line, we must pay attention to the coordination of supporting issues.
