The image shows the interior of a train car with two windows on either side. Above the windows, there is a large map of the train system displayed on the wall. The map is in blue and red colors and shows the various lines and stations in the train. The lines are arranged in a grid-like pattern, with each line representing a different train station. The stations are labeled with numbers and letters, and there are also some information about the train's layout. The ceiling of the car is white, and the windows are open, allowing natural light to enter the space.
