解放以前,我国铁路上除了几个破破烂烂的修理工厂以外,几乎没有什么机车车辆工业可言。在线路上跑的机车车辆来自世界各大洲,我国的铁路成了万国机车车辆产品的展览会场。建国以来,由于党和国家的关怀和大力支持,仅仅用了十几年的时间,已经彻底改变了这种半殖民地的面貌。现在我国铁路上所需要的机车车辆,无论在品种或数量上,已经基本上可以自给自足。同时,为了满足兄弟国家或友好国家的需要,还出口了一些机、客、货 Before the liberation, there was hardly any locomotive and rolling stock industry on the railway except for a few dilapidated repair factories. The locomotives and buses that run on the roads come from all continents. The railways in our country have become the exhibition grounds for the products of locomotives and locomotives. Since the founding of the People’s Republic of China, due to the care and strong support of the party and the country, it took only a decade or more to completely change the appearance of this semi-colonial. At present, the locomotives and vehicles that are needed on China’s railways can basically be self-sufficient in terms of variety or quantity. At the same time, in order to meet the needs of fraternal countries or friendly countries, some machines, passengers, and goods have also been exported.
