The Higashi-Ikoma depot was established at the start of operations between Nagata Station and Ikoma Station, and until around November 2005, when trial operations started between Ikoma Station and Gakken-Nara-Tomigaoka Station, the outbound main-line portion between the current Ikoma Station and Higashi-Ikoma Signal Station (the track toward Gakken-Nara-Tomigaoka Station) was used as the line for a depot.
東生駒車庫は長田～生駒間開業時に設置された車庫で、生駒～学研奈良登美ヶ丘間で試運転が開始された2005年11月頃までは現在の生駒～東生駒信号場間の下り（学研奈良登美ヶ丘方面）本線を車庫線として使用していた。
