(一)提高运输能力的途径随着我国四化建设的不断发展,铁路所应担负的运输量也不断提高。为此,有必要进一步提高铁路的运输能力。提高运输能力的手段主要有:①建新线;②改造旧线;③由单线过渡到复线甚至三线;④改造牵引动力;⑤采用大型车辆等。不论是建新线,还是改造旧线,都可以采用自动闭塞、调度集中,适当延长到发线长度、增设车站、改善线路的纵断面与平面布置,降低线路限制坡度等措施,来提
(I) Ways to improve transport capacity With the continuous development of the four modernizations in our country, the volume of transport that railways should shoulder is also on the increase. Therefore, it is necessary to further improve the transport capacity of the railway. The main means to improve transport capacity are: ① build a new line; ② transform the old line; ③ transition from single to double or even three lines; ④ transform traction power; ⑤ large vehicles and so on. Whether it is to build a new line or to rebuild the old line, automatic blocking and centralized scheduling can be adopted to appropriately extend the length of the hairline, add more stations, improve the vertical and horizontal layout of the lines, and reduce the limit of line restrictions
