上海局管内开行的沿(途)零(担)列车,货车平均载重17.5t,只占全局平均静载重的36%;列车限编20辆,占常规牵引定数的40%左右;而且平均旅速只12.5km/h(快沿零),运营效率低。停开一列沿零列车,一般在复线自动闭塞区段可加开3.5对货物列车,在单线半自动闭塞区段可加开1.5～2对货物列车,潜力较大。而且沪宁线等沿线与内河、公路、长江四线平行,公路网遍及城乡,联运事业发达;地方交通运输不仅能力有余,而且任务吃不
The freight trains carried an average load of 17.5 tons (accounting for 36% of the overall average global dead weight) along the (transit) train operated by the Shanghai Municipal Bureau; 20 train trains, accounting for about 40% of the conventional traction numbers; and the average speed Only 12.5km / h (fast along zero), low operational efficiency. Stop a train along the zero, usually in the automatic block section of the double-line can be added to open 3.5 pairs of cargo trains in the single-lane semi-automatic block section can be added to open 1.5 to 2 cargo trains, great potential. And the Shanghai-Nanjing line along the river and other roads, the Yangtze River parallel to the four lines, the road network throughout urban and rural areas, the development of inter-transport; local transport is not only more than capacity, and the task to eat or not
