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 from Shin-Tsudanuma to Yakuendai, on 27 December 1947. The Yukuendai–Takifudo section was reopened in 1948, and extended to Hatsutomi the following year.

The reopened sections were regauged to in October 1953, and the entire line was reopened as a single-track line by 21 April 1955. In August 1959, the line was again regauged, this time to to match the standard gauge used by Keisei Electric Railway.
