The Shinomiya depot, a rail yard for train cars on the Keishin Line, is located on the north side of this station, but it looks somewhat small because the depot, which was originally provided for two-car trains, has been updated to accommodate four-car trains.
駅の北側に京津線の車両基地である四宮車庫が設置されているが、もともと2両編成時代のものを4両化に合わせてリフォームしたもので、窮屈に見える。
