Denmark has been operation with the same company since she was built in 1861. Sailing passengers to and from Silkeborg and Himmelbjerget ever since, using her original steam engine she was built with. Norway is the oldest steamship in regular operation. Built in 1856, she still operates on lake Mjøsa in Norway. Switzerland Switzerland has a large paddle steamer fleet, most of the "Salon Steamer-type" built by Sulzer in Winterthur or Escher-Wyss in Zurich. There are five active and one inactive on Lake Lucerne, two on Lake Zurich, and one each on Lake Brienz, Lake Thun and Lake Constance. Swiss company CGN operates a number of paddle steamers on Lake Geneva. Their fleet includes three converted to diesel electric power in the 1960s and five retaining steam. One, Montreux, was reconverted in 2000 from diesel to an all-new steam engine. It is the world's first electronically remote-controlled steam engine and has operating costs similar to state-of-the-art diesels, while producing up to 90 percent less air pollution.

France No paddle ship is currently in operation in France as of 2015 (though some Paris sightseeing tourist crafts sport a dummy sternwheel powered by a hydraulic motor). In Lac D'Annecy an almost intact paddle steamer called la France, resting on an even keel, can be visited by advanced divers (resting at deep). She was built, like most of its Swiss counterparts by Escher-Wyss in 1909 (as a CKD dismantled kit to be transported by railway and assembled at the local annecy Puya Shipyard) and ran a regular line around Lac d'Annecy. During World War II the ship was laid up in Annecy and used as a prison by the German occupying forces and the Gestapo. La France made her last commercial voyage in
