Most trains operate throughout the line, although during the morning hours, some services terminate at Shin-Tsudanuma.

During the daytime, Shin-Keisei runs alternate through trains to Chiba-Chūō on the Keisei Chiba Line.

The line was originally opened in 1929 with a track gauge of 1,067 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) from Shin-Tsudanuma to Yakuendai, on 27 December 1947.
