doors inside a train car while the train is in motion

doors inside a train car while the train is in motion. The doors are metallic and have windows, through which a blurry image of another train car can be seen. The other train car is white with blue and red stripes and has a logo with a green leaf and the letters SNCF. The interior of the train car is well-lit. There is a vertical silver pole and a door-opening mechanism with a green button. Occasional blurry silhouettes of people can be seen reflected in the windows of the doors.
