On lake Luzerne (Lucerne) in Switzerland, beautiful passenger ships that are more than 100 years old still cross the lake on a regular basis. In this photo, you can see the engines of the ship "Uri" in action while the ship is crossing the lake. The engine goes back to 1901. On the sides, you can see the paddles which are turning to propell the ship forward. The stairs lead to the 1st class deck which is upstairs.
