Lausanne is one of the main cities in Switzerland, and the 2020 Winter Youth Olympics are also held here. In the morning, I passed Lausanne on the way from Lusen to Fort Dei by train. Lausanne is an ancient city with a long history. Switzerland is a multilingual area. French is the main language in Lausanne. Of course, English can also be communicated here. There are also many people who come to Lausanne to ski, and many passengers who bring their own ski equipment on the train. The famous attractions of Lausanne include the Olympic Museum and the Cathedral of Lausanne.
