随着秦沈客运专线的运营,沈山线从客货混跑,逐步转变为以货为主、兼顾客车进出关的主要通道之一。区段通过能力的增加,车站通过能力的加强,是沈山线电气化改造的关键。 With the operation of the Qin-Shen Passenger Dedicated Line, the Shen-Shan Line has been gradually transformed from a passenger and cargo mixed operation to one of the major thoroughfares that take cargo as the mainstay and give consideration to the entry and exit of passenger cars. The increase of capacity through the section and the enhancement of station passing capacity are the keys to the electrification of Shen Shan Line.
