Picture a short movie about natural beauties of Germany, through whole movie you see movement (transparent shape of train). While traveling throug the forrest you can see animals, plants, flowers not "aware" of train passing by. At the end train rushes into the train station in a cloud of greenery (like opening of a passage between the worlds with the plants braces around the edge of the round opening), becomes "solid" (something like on a picture), and people come out - tourists, business people, family...
