An exclusive line connecting these facilities for the army was laid (there were three lines such as Hoshida Station Kori factory, Tsuda Station Nakamiya (Kinya magazine) and the present-day Shimokoma Station vicinity of the Hosono ammunition chamber).
これらの施設までは陸軍の専用線が敷設されていた（星田駅-香里製造所・津田駅-中宮（禁野火薬庫）・現在の下狛駅付近-祝園弾薬庫の3線）。
