作为中国煤炭运输的大动脉之一,大秦铁路一边扩能改造,一边增加运量,数年间其年运量便从1亿吨增长到3.3亿吨之多。图中这些可敬可爱的路基维修工们,便是在扩能改造方面创造奇迹的铁路职工们中的代表,是铁路向前延伸、火车多拉快跑必不可少的基石。 As one of the major arteries of China’s coal transport, the Daqin Railway has expanded its capacity and capacity while increasing its capacity. In just a few years, its annual traffic volume increased from 100 million tons to as much as 330 million tons. These respectable and lovely subgrade repairers are representatives of railway workers who have won the miracle in capacity expansion and renovation. They are the cornerstone for the railway to extend forward and run fast on the train.
