History
The Shinonoi to Nishijo section opened in 1900, and was extended via Matsumoto to Shiojiri in 1902.{{citation needed|date=November 2016}}
The Shiojiri to Matsumoto section was double-tracked between 1961 and 1965, with the Tazawa to Akashina section double-tracked in 1966. The Akashina to Nishijo section was also double-tracked, but the original line was decommissioned in 1988.{{citation needed|date=November 2016}}
The Shiojiri to Matsumoto section was electrified in 1964/5, and extended to Shinonoi in 1973, CTC signalling being commissioned on the entire line the previous year.{{citation needed|date=November 2016}}
Station numbering was introduced on the Nagano area from February 2025, with Shinonoi Line stations numbered using the prefix "SN". Numbers increase towards Shinonoi.{{cite web |title=ＪＲ東日本長野支社管内へ「駅ナンバリング」を拡大します |url=https://www.jreast.co.jp/press/2024/nagano/20241213_na02.pdf |website=East Japan Railway Company |access-date=8 April 2025 |language=Japanese |date=13 December 2024}}
