一、总结经验,合理计划自1961年我国第一条电气化线路—宝凤线建成至1976年的十六年间,由于十年动乱,电气化运输未能得到很好的发展。随着国民经济迅速发展,要求铁路运输改变长期与国民经济发展严重不相适应的状态。我国在近几年间,先后建成了襄渝、阳安、石太、兰宝等线。但是因受机车种类单一的限制,并缺乏准确的远期沿线运量预测的资料和数据,只能根据机车的牵引力和线路限坡等因素来确定列车的牵引定数、列车通过对数等定额。因此,一些线路用单机牵引时,运能很快就饱和了。用双机牵引时,列车长度受到发线长度限制,牵引定数增加不多,机车功率损失较大,效率低,因而
I. Summary of Experiences and Rational Planning Since 1961, the first electrified line in our country - Bao Feng Line was completed in 1976 to 16 years, due to the ten years of turmoil, electrified transport has not been well developed. With the rapid development of the national economy, rail transport is required to change its state of being incompatible with the long-term development of the national economy. In recent years, our country has built Xiangyu, Yang’an, Shitai, Lanbao and other lines. However, due to the single type of locomotive and the lack of accurate data and data for traffic forecast along the long-term, the number of trains can only be determined according to the tractive force of the locomotive and the slope of the line. The number of trains is fixed by logarithm. Therefore, some of the lines with a single traction, transport capacity will soon be saturated. When towing with double machine, the length of train is limited by the length of hairline, the increase of traction number is small, the power loss of locomotive is large and the efficiency is low, thus
