Since 2015, all Sennichimae Line trains support
automatic train operation (ATO) with
one-person operation as fallback. ATO was previously trialled on the Sennichimae Line between October 1973 and July 1974.
Until 2011, the Sennichimae Line had a depot near Imazato station. Nowadays, Sennichimae Line rolling stock are stored at Morinomiya Depot on the Chūō Line where it is linked via a connecting track at Awaza. Since 2016, the regular inspection of the trains used on the third rail lines of Osaka Metro has been consolidated at Midorigi Depot on the
Yotsubashi Line, so a new spur track has been constructed near
Hommachi Station for Sennichimae Line trains to access Midorigi Depot.
