近日(ri)，中鐵電(dian)(dian)氣化局中標(biao)新建(jian)鐵路(lu)太原至(zhi)中衛（銀(yin)川(chuan)）線(xian)站后四電(dian)(dian)工(gong)程項目最(zui)大(da)標(biao)段(duan)—太原南至(zhi)山(shan)陜省界段(duan)。該標(biao)段(duan)全長218正線(xian)公(gong)(gong)(gong)里(li)(li)(li)，總造價11.74億元。主要(yao)工(gong)程數量包括通信光電(dian)(dian)纜1008公(gong)(gong)(gong)里(li)(li)(li)，自動閉塞203.4區(qu)間公(gong)(gong)(gong)里(li)(li)(li)，聯鎖道(dao)岔(cha)141組，電(dian)(dian)力(li)線(xian)路(lu)644.8公(gong)(gong)(gong)里(li)(li)(li),接觸網(wang)導線(xian)772.3條(tiao)公(gong)(gong)(gong)里(li)(li)(li),供電(dian)(dian)線(xian)67.6條(tiao)公(gong)(gong)(gong)里(li)(li)(li),回流(liu)線(xian)518.3條(tiao)公(gong)(gong)(gong)里(li)(li)(li),給排水(shui)管道(dao)77公(gong)(gong)(gong)里(li)(li)(li)。建(jian)成后，除承擔沿線(xian)的客貨(huo)運輸任務外，還可以分流(liu)隴海和包蘭(lan)、京(jing)包南北(bei)兩(liang)條(tiao)鐵路(lu)的客貨(huo)運輸，使(shi)西(xi)部地區(qu)至(zhi)華北(bei)主要(yao)城市的運輸距(ju)離縮短(duan)100-150km，將成為西(xi)北(bei)地區(qu)通往東部最(zui)便捷的鐵路(lu)通道(dao)，對緩解南北(bei)相鄰(lin)路(lu)網(wang)的運輸壓(ya)力(li)，增加路(lu)網(wang)的機動性等起到積極作用。
