interior of a train car

interior of a train car. On the left side, there is a window with trees visible outside, suggesting a rural or forested area. The interior walls appear to be white with some discoloration and peeling paint. To the right of the window is a doorway with a glass panel. On the glass, the number "2" is prominently displayed in black. Below the "2" is a rectangular sign with a red circle and a diagonal line through a cigarette, indicating "no smoking." The corridor beyond the doorway appears long and narrow, with multiple doors on either side, suggesting passenger compartments. The floor is covered with dark, textured material, possibly rubber matting. The overall impression is of an older, functional train car. The location is Gornje Leskovice, Serbia.
