STRABAG AG<\/a> is carrying out the outstanding renovation work on the Zentralbahn line between Meiringen and Brienzwiler in the Bernese Oberland. The narrow-gauge line runs on a single track along the Hasliaare, which is part of the Aare flood plain. Out of consideration for several nature conservation areas, “maximum precision for logistics and coordination” is required for the new construction, according to a press release<\/a>. Preparatory work began in March 2025 and the ten-week intensive phase has been underway since October 2025.<\/p>\n\n\n\n\n\n

Heavy rainfall events had repeatedly occurred in the area, causing the railroad embankment and superstructure to flood, resulting in damage to the railroad infrastructure and adjacent cultivated land. STRABAG already carried out track construction work there in 2022 and 2023 (lots 1 and 3). The modernization project will now be completed with a total reconstruction of the challenging middle section of lot 2 over a length of 2600 meters and in the middle of the Sytenwald nature reserve. This involves raising the railroad embankment. To allow surface and slope water to drain away, a continuous planned drainage system will be installed along the route. The area along the Hasliaare will receive a new flood protection wall. <\/p>\n\n\n\n\n\n

According to the press release, the “tight space conditions and local lack of redundant construction slopes in certain sections between the Hasliaare, the railroad line and several nature conservation areas” are a special construction feature, which requires special precautions for ecology and landscape protection. On the one hand, STRABAG is building 30 new foundations for the catenary masts on the side facing away from the river, and on the other, 37 crossings are to ensure the ecological continuity of the terrain. This means protection for wildlife and small animals when crossing the section.<\/p>\n\n\n\n\n\n

A particularly challenging component is the new construction of the H\u00fcsenbach bridge made of ultra-high-strength and durable fiber-reinforced concrete (UHPC). During bridge construction, special consideration was given to the trout population present there at spawning time.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
