一、京广、津浦线技术改造简要情况 京广和津浦两线都是在解放以前修建的。受当时历史条件的限制,原有铁路质量较差,技术标准也低,以后又遭多次战争的严重破坏。新中国成立后,着手抢修线路,改善设备质量,保证正常通车,逐步开始了全面的技术改造。 在单线运营期间,这两条线都采取了各种技术改造措施来挖掘单线设备的潜力。以后,运量不断增长而单线能力又不敷需要的情况下,这两条线较早动手进行修建双线,但都经历
First, the Beijing-Guangzhou, Jin Pu briefing on the technological transformation Jingguang and Jinpu two lines were built before the liberation. Due to the historical conditions at that time, the quality of the original railway was poor and the technical standards were also low. Afterwards, it was severely damaged by many wars. After the founding of New China, embarked on repair and repair lines to improve the quality of equipment to ensure normal operation, and gradually started a comprehensive technological transformation. During the single-line operation, both lines took various technological modifications to tap the potential of single-wire equipment. In the future, with the continuous increase in traffic volume and the lack of capacity for single-line operations, the two lines started the construction of two lines earlier but both experienced
