在我国“七五”国民经济发展期间,铁道部为适应国民经济的迅速发展,提出以扩能为中心,提高综合运输能力的战略部署,综合技术改造必须紧紧围绕重载、扩编进行。目前,铁路的运能已不适应我国国民经济发展的要求。依靠增加新建线路的方法来解决运量及运能的矛盾,国家投资大、需要的时间长。比较理想的办法是采用新的科学技术开行重载列车或组合列车提高现有线路的通过能力,这种方法仅需改造部分线路就可以明显地提高现有线路的
During the “Seventh Five-Year Plan” national economic development in our country, in order to meet the rapid development of the national economy, the Ministry of Railways proposed a strategic deployment of expanding capacity as the center and improving the comprehensive transport capacity. The comprehensive technological transformation must focus on reloading and expansion. At present, the transport capacity of the railway is no longer suitable for the development of our national economy. Relying on the method of adding new lines to solve the contradiction between capacity and capacity, the country needs a long time to invest heavily. The ideal solution is to adopt new science and technology to operate heavy-haul trains or combined trains to improve the passing capacity of existing routes. This method can significantly improve the existing routes
