近日，中(zhong)鐵(tie)電(dian)氣化局(ju)中(zhong)標(biao)新建鐵(tie)路(lu)(lu)太(tai)原至(zhi)(zhi)中(zhong)衛（銀川）線(xian)(xian)(xian)站(zhan)后四電(dian)工(gong)(gong)程項目最(zui)大標(biao)段(duan)(duan)—太(tai)原南(nan)至(zhi)(zhi)山陜省界段(duan)(duan)。該標(biao)段(duan)(duan)全長218正線(xian)(xian)(xian)公(gong)(gong)(gong)里(li)，總造(zao)價11.74億(yi)元。主(zhu)要(yao)工(gong)(gong)程數量包括通(tong)信(xin)光電(dian)纜(lan)1008公(gong)(gong)(gong)里(li)，自(zi)動(dong)閉塞203.4區(qu)間(jian)公(gong)(gong)(gong)里(li)，聯鎖道岔141組(zu)，電(dian)力(li)線(xian)(xian)(xian)路(lu)(lu)644.8公(gong)(gong)(gong)里(li),接觸網(wang)(wang)導線(xian)(xian)(xian)772.3條(tiao)公(gong)(gong)(gong)里(li),供(gong)電(dian)線(xian)(xian)(xian)67.6條(tiao)公(gong)(gong)(gong)里(li),回流(liu)線(xian)(xian)(xian)518.3條(tiao)公(gong)(gong)(gong)里(li),給排水管道77公(gong)(gong)(gong)里(li)。建成后，除承擔沿線(xian)(xian)(xian)的(de)(de)客(ke)貨(huo)運(yun)(yun)(yun)輸任務外，還可以(yi)分流(liu)隴海(hai)和包蘭、京包南(nan)北(bei)兩條(tiao)鐵(tie)路(lu)(lu)的(de)(de)客(ke)貨(huo)運(yun)(yun)(yun)輸，使西部地(di)區(qu)至(zhi)(zhi)華北(bei)主(zhu)要(yao)城市的(de)(de)運(yun)(yun)(yun)輸距(ju)離縮短100-150km，將成為西北(bei)地(di)區(qu)通(tong)往東部最(zui)便捷的(de)(de)鐵(tie)路(lu)(lu)通(tong)道，對(dui)緩解南(nan)北(bei)相鄰路(lu)(lu)網(wang)(wang)的(de)(de)運(yun)(yun)(yun)輸壓力(li)，增加路(lu)(lu)網(wang)(wang)的(de)(de)機(ji)動(dong)性等起到(dao)積極作(zuo)用(yong)。
