铁路运输是国民经济的大动脉,是社会主义建设的“先行官”。铁路运输能力的大小,将直接影响国民经济的发展和国防建设的需要。增强铁路运输能力的重要措施,是进行牵引动力改革,采用电力牵引和内燃牵引逐步代替蒸汽牵引,并相应地进行运营管理体制改革。与蒸汽牵引相比,新型牵引动力整备作业少(不需上煤上水清灰)、生产规模大(长距离运行)、运营效率高(多拉快跑),大大
Railway transportation is the main artery of the national economy and the “pioneer” of socialist construction. The size of railway transport capacity will directly affect the development of the national economy and the needs of national defense construction. An important measure to enhance railway transport capacity is to carry out traction reform, gradually replace steam traction with electric traction and internal combustion traction, and reform the operation and management system accordingly. Compared with the steam traction, the new traction power trim less (without ash on the water), large-scale production (long distance operation), high operational efficiency (Dora run), greatly
