The eight-kilometer section starts at the east train station in Mayen, which can be reached by regional train. It lies on the route of the Eifelquerbahn. This runs every hour between Andernach on the left Rhine route and Kaisersesch. The route then leads in the district of Hausen with a slight incline into the Nette valley, which is bridged with the help of an approximately 40 meter high natural stone viaduct. The route runs along the route of the former Koblenz-Lützel - Mayen Ost railway line. Behind the viaduct over the Nette valley, it goes through the 252 m long Hausen-2 tunnel, which is followed by the Lehnener viaduct. With a length of 82 m, this only has a height of 8 m. Immediately afterwards follows the Hausen-1 tunnel with a length of 500 m. Both tunnels are illuminated. The route climbs slightly from the Nette valley and passes the village of Nettesürsch. The A48 motorway is then crossed with a slight downward gradient before the cycle path junction at the former Polch train station is reached.
