An indoor metro station platform in Sofia, Bulgaria, features a stationary train

An indoor metro station platform in Sofia, Bulgaria, features a stationary train. The train, number "2027," is white with a dark green horizontal stripe and closed doors. Horizontal yellow blinds or a textured film cover the windows, partially obscuring the interior. Three individuals are visible within the train: one seated person with reddish-brown hair wearing a light green jacket, and two standing figures in dark attire further inside. In the foreground, a vertical, multi-faceted structural column or platform barrier stands between the viewer and the train. It is decorated with a brown, beige, and white geometric pattern. On its upper section, a white panel displays "1-2" along with three red-crossed-out circular symbols prohibiting smoking, eating/drinking, and animals. The platform floor is tiled with alternating light brown/terracotta and beige square tiles. A yellow tactile paving strip marks the platform edge, with a thin yellow painted line running parallel behind it. The ceiling is light-colored and features several circular, surface-mounted LED light fixtures emitting bright white light, casting distinct beams into the dark upper area of the station. Metal rails and infrastructure are visible overhead.
