铁路运输是一个大的金属需要部门。交通部所属企业的需要量约占全国生产的金属的3％,还不包括以机车车辆形式供应的金属。单位运输产品金属用量稳定增长的趋势,说明供给运输部门的金属未能充分有效地利用。所以铁路运输部门节约金属问题值得充分的重视。线路部门用去了供给交通部的金属的一半以上。
Rail transportation is a big metal needs department. Ministry of Communications owned enterprises accounted for about 3% of the country’s production of metal, does not include the supply of motor vehicles in the form of metal. The steady growth of the metal consumption of transport products per unit shows that the metals supplied to the transport sector have not been fully and effectively utilized. Therefore, the issue of metal saving in the railway transport sector deserves full attention. The line department used more than half of the metal supplied to the Ministry of Transportation.
