Abstract
For better comfort of passengers on the subway, a projector can be used. It can be mounted in the wall of the wagon so the image would appear outside on the well prepared wall of the subway tunnel. The wall of the tunnel needs to be prepared and painted white. For the legibility of the image, laser sensors of distance can be mounted by the projector. These can give a good focused image even on the walls which are in different distances from the wagon.
