I think this picture is taken inside the train. In the train there is a restaurant filled with the tables, chairs and people. Tables are arranged on either side of the train. in the middle there is a lane. At the bottom right there are two men sitting on either side of the table. On the table there are glasses, cups, menu card, a jacket are placed. At the bottom left there is a man and woman sitting on either of the table. On the windows of the train, there are curtains.
