近日(ri)，中鐵(tie)電氣化局(ju)中標(biao)新建鐵(tie)路(lu)太原(yuan)至中衛（銀川）線(xian)站(zhan)后四電工程(cheng)項目(mu)最(zui)大標(biao)段(duan)—太原(yuan)南(nan)至山陜省界(jie)段(duan)。該標(biao)段(duan)全長(chang)218正線(xian)公(gong)(gong)里(li)(li)，總(zong)造價11.74億元(yuan)。主要(yao)工程(cheng)數量包括通信(xin)光電纜1008公(gong)(gong)里(li)(li)，自動閉塞203.4區間公(gong)(gong)里(li)(li)，聯(lian)鎖道(dao)(dao)岔141組，電力線(xian)路(lu)644.8公(gong)(gong)里(li)(li),接觸網導(dao)線(xian)772.3條(tiao)公(gong)(gong)里(li)(li),供電線(xian)67.6條(tiao)公(gong)(gong)里(li)(li),回流線(xian)518.3條(tiao)公(gong)(gong)里(li)(li),給排水管道(dao)(dao)77公(gong)(gong)里(li)(li)。建成后，除承擔(dan)沿線(xian)的客(ke)貨運(yun)輸(shu)(shu)任務外(wai)，還可(ke)以(yi)分流隴海和(he)包蘭、京包南(nan)北(bei)(bei)兩條(tiao)鐵(tie)路(lu)的客(ke)貨運(yun)輸(shu)(shu)，使(shi)西部地(di)區至華北(bei)(bei)主要(yao)城市的運(yun)輸(shu)(shu)距離縮短100-150km，將成為西北(bei)(bei)地(di)區通往東部最(zui)便捷的鐵(tie)路(lu)通道(dao)(dao)，對緩解南(nan)北(bei)(bei)相鄰路(lu)網的運(yun)輸(shu)(shu)壓力，增加(jia)路(lu)網的機動性等(deng)起到(dao)積極作用。
