After the electrification, the operation of the Limited Express 'Kitakinki' started and the number of local trains available every hour during the day increased to three, mainly with two cars of the JNR/JR Suburban Train Series 113 (one for operation between Osaka and Fukuchiyama and two for operation between Osaka and Shin-Sanda); however, it wasn't sufficient to have two cars so many of the local trains were packed with too many passengers and experienced successive delays, thereby resulting in many complaints about, for example, bumped passengers, especially for the trains after 22:00 to the last train.
全線電化以降、電車特急「北近畿」の運転開始に加え、普通電車は国鉄113系電車2両編成を主体として日中毎時3本（1本が大阪～福知山、2本が大阪～新三田）に増発されたが、2両編成は短過ぎて多くの列車で満員となり遅延が続発、特に22時台以降から最終電車にかけては時に積み残しが出るなど苦情が相次いだ。
