A drastic change for the Fukuchiyama Line came in 1986, when the section between Takarazuka and Shin-Sanda was double-tracked and all the sections up to Fukuchiyama were electrified (the electrification was extended to Kinosakionsen Station on the Sanin Main Line).
福知山線にとって劇的な変化が起こるのは、1986年に宝塚～新三田間の複線化、福知山までの全線電化（電化は山陰本線城崎温泉駅まで）が完成してからである。
