Windows of the train are the TVs.

The windows offer a view that would not usually be seen. The TV gives images that are exciting and convey different emotions. The horses running are peaceful. The sun is powerful and the indian scene is interesting and fun. The different scenes appear to different people who seek different forms of intellectual stimulation in their lives. Same idea as the "eyes are the window to the soul." The images aren't real. People want to be in a fantasy sometimes and escape life. People want to be entertained and transported to a different place. The train transports people to different places literally and the TVs transport people's minds. The TVs show nothing that is sad or upsetting. When we look out a window we sometimes see things we want to see and other times we see things that we would never want to see. The TVs make life better. If you have the TV in your house you will always view beautiful things with clarity. The TV doesn't have graffiti on it and the windows are not scratched. Initials aren't etched into the windows. The screen is perfect. Who wouldn't want to live in a perfect world? The TVs seem just like reality because the little boy and the little girl seem to make contact. The TV is not just something to watch. Watching TV is known to be a passive activity, but in this commercial the little boy runs after the train to stay in contact with the little girl and the little girl moves her hand. Her face lights up when she looks at the TV. Her brain is working. The windows could be anything you like. You can choose channels. The TVs can even offer you to be in your favorite movie or watch your favorite movie unfold outside your "window." You can teleport. The destination is unkown because the TVs are always changing scenes. This makes it seem like the train ride is adventurous. Everyone wants some adventure. The destination however will probably be somewhere magical or somewhere dull and depressing, because you will have to be in the real world and not be viewing the world through a TV. Plays on the way modern society uses TV. People sit and watch TV programs to better understand the world.
