1998年10月1日实行新的运行图后,京广干线实现了全线提速,尤其快速旅客列车的开行,大大提高了列车运行速度,方便了旅客旅行,从而吸引了众多的客流,为铁路参与运输市场的竞争,扩大市场占有份额提供了契机。实践证明,京广线开行快速旅客列车,不仅取得了良好的经济效益,同时还收到了良好的社会效益。由于京广线的提速工程属既有线改造,鉴于资金、技术和地理环境等因素的限制,有些地段的改造还不能一步到位,因此新图实施后,仍保留了部分允许通过速度在100公里/小时以内的限速区段。位于七里营至新乡间第Ⅱ正线上的唐庄大桥就是其中一例,该桥虽经加固改造,但通过速度也仅能提高到100公里/小时,致使提速工作的整体性受到一定影响。
After the implementation of the new operating plan on October 1, 1998, the Beijing-Guangzhou trunk line has achieved speeding across the board. In particular, the opening of fast passenger trains has greatly accelerated the speed of trains and facilitated the travel of passengers, thus attracting numerous passenger traffic and providing railway participation Transport market competition, expanding market share provides an opportunity. Practice has proved that the Beijing-Guangzhou line opened fast passenger train, not only achieved good economic returns, but also received good social benefits. As the Beijing-Guangzhou line speeding project is a transformation of existing lines, due to capital, technology and geographical constraints and other factors, the transformation of some sections can not be achieved in one step, so after the implementation of the new map, still retains part of the allowable speed of 100 km / Speed limit within hours section. An example is the Tangzhuang Bridge on Qilixian of Qixiying to Xinxiang. Although the bridge has been reinforced and rebuilt, the passing speed can only be increased to 100 km / h, resulting in a certain impact on the integrity of speed-raising work.
