Norman Switzerland is crossed by two railway lines connecting Caen to Flers on the one hand and Berjou to Falaise on the other. These two lines are punctuated by several works of art - bridges, viaducts, and tunnels - to adapt to the relief of the Orne and its tributary valleys. The most notable of them are the bridges of Feuguerolles and Pont-d'Ouilly ; the Pouquet, Sainte-Anne, La Lande or Clécy (photo), Bordeaux, Mesnil-Villement, and Rapilly viaducts as well as the Hom and Gouttes tunnels.
