为了满足我国铁路运输日益增长及行车速度不断提高的需要,铁道部决定在今后几年内主要干线上要更换60公斤钢轨,而60AT钢轨是60公斤钢轨线路铺设的组成部分。为了使运输不造成困难,必须提供一定数量道岔轨为站线和正线上使用。在铁路网中,平均500米线路就需要一付道岔轨(瑞士455米一付)。道岔轨是用在铁路道岔的地方,其一端与60公斤钢轨靠紧,该端必须加工成较尖的楔形
In order to meet the needs of our country’s increasing railway traffic and increasing traffic speeds, the Ministry of Railways decided to replace 60 kilograms of rails on major trunk lines within the next few years, and 60AT railways were part of laying 60 kilograms of rail lines. In order not to cause any difficulty in transportation, a certain number of turnout rails must be provided for the station line and on the main line. In the railway network, an average of 500 meters on the line will need to pay a turnout (Swiss 455 meters). Turnout rails are used at railroad turnouts, with one end abutted against a 60kg rail and the end must be machined to a pointed wedge
