A subway train approaches and passes through an underground station or tunnel. Bright headlights illuminate the dark tunnel as the train emerges, with a red signal light visible on the tunnel wall to the left of the tracks. The train is predominantly grey with blue and white stripes along its lower body. A digital destination display on the front of the train shows Cyrillic text, which reads "УЛ. Б. ДМ. ДОНСКОГО" (Ul. B. Dm. Donskogo), indicating a destination in Moscow. A person can be seen in the driver's cabin. The train quickly moves past the camera, revealing its side with multiple windows and doors. The platform features a yellow safety line. The tunnel wall to the left is adorned with numerous cables, conduits, and structures, including a white sign marked with the number "2374".
