The line was originally opened in 1929 with a track gauge of1,067 mm (3 ft 6 in) for army training purposes, and ceased to be used in 1945.^{[citation needed]}

The line was transferred to the Shin-Keisei Railway, which reopened and electrified at 1,500 V DC (overhead) the first section of the line, 2.5 km (1.6 mi) fromShin-Tsudanuma toYakuendai, on 27 December 1947.^[3] The Yukuendai–Takifudo section was reopened in 1948, and extended to Hatsutomi the following year.^{[citation needed]}

The reopened sections were regauged to1,372 mm (4 ft 6 in) in October 1953, and the entire line was reopened as a single-track line by 21 April 1955.^[3] In August 1959, the line was again regauged, this time to1,435 mm (4 ft 8+1⁄2 in) to match the standard gauge used byKeisei Electric Railway.^[3]

On 31 October 2023, it was announced that the Shin-Keisei Line would be merged into the Keisei Electric Railway and renamed to theMatsudo Line (松戸線,Matsudo-sen). The move is expected to be completed by April 2025.^[4][5][6]
