鹰厦线鹰（潭）来舟段，自1991年5月份电化开通后，为减缓北段运能紧张状况起到了积极的作用（运量从1990年的3700万吨增加至1993年的5000万吨）；同时由于山区铁路曲线多、半径小、坡度大，电化后轴重的增加、牵引吨位的加大，使设备破损严重、轨道几何状态变化加大，给养护维 The eagle Eagle (Lake) to the boat section, since May 1991 electrification opened, to ease the tension in the northern section has played a positive role (volume from 37 million tons in 1990 increased to 50 million in 1993 Ton). At the same time, as the railway in mountainous area has many curves, small radius, large slope and increased axle weight after electrification, the traction tonnage will increase so that the equipment will be severely damaged and the orbital geometry will change more.
