铁路旅客运输,在其它各种运输方式发展的同时,仍发挥着重要作用。铁路运输在节省动力资源和减少环境污染方面都是比较重要的。它能有效地利用电力,而这种电力是在利用廉价的矿物燃料、水力和原子能的基础上获得的。近年来,在所有发达的国家中,铁路旅客周转量出现了增长的趋势。运输量的增长就要求经常地提高铁路输送能力和通过能力。解决这个课题的方法乃是发展铁路网和加强运输技 Rail passenger transport still plays an important role in the development of other modes of transport. Railway transportation is more important in saving power resources and reducing environmental pollution. It can effectively use electricity, which is based on the use of cheap fossil fuels, water and atomic energy. In recent years, the railway passenger turnover has shown an upward trend in all developed countries. The increase in volume of transportation requires frequent improvements in the capacity and capacity of the railways. The solution to this issue is to develop the railway network and strengthen transport skills
