我国在解放初期,铁路运营里程为2万多公里,现在已达5万余公里,除西藏外,各省、市、自治区均有铁路。全国路网骨架基本形成,运输能力大提高。1979年全国货运量为1949年的19倍,客运量为8倍。我国通过三十年的铁路建设,积累了不少的经验。回顾一下过去修建铁路和运营的经验教训,作为对今后修建铁路的借镜,提出如下看法,以供参考。一、线路限制坡度问题: 铁路线路限制坡度选择是否恰当,是决定工程投资、运输能力以及运营支出的重大问
In the early days of the liberation of our country, the mileage of railway operation was over 20,000 kilometers and now it has reached 50,000 kilometers. Except for Tibet, all provinces, municipalities and autonomous regions have railways. The basic formation of the national road network skeleton, transport capacity increased. In 1979, the national freight volume was 19 times that of 1949 and the passenger traffic was 8 times. Through 30 years of railway construction in our country, we have accumulated a lot of experience. Recalling the past experiences of building railways and operations as a reference for the construction of railways in the future, the following observations are made for reference. First, the line to limit the slope problem: the appropriate choice of railway lines to limit the slope, is to determine the project investment, transport capacity and operating expenses major question
