ABS 36 Brenner North Access Route Planning Sections PA1 and PA3

The project comprises the design of the approximately 15-kilometre-long new line section between Grafing and Ostermünchen in Planning Section 1 (PA 1), as well as the roughly 25-kilometre-long new line section in Planning Section 3 (PA 3) between Innleiten (Inn crossing near Rosenheim) and Kirnstein (near the Niederaudorf junction). Both sections form part of the northern access route to the Brenner Base Tunnel and thus belong to the Scandinavian–Mediterranean Corridor (Scan–Med Corridor), Europe’s most important north–south railway axis stretching from Finland to Malta.

In addition to the open-track sections, the project includes the design of all associated transport infrastructure such as bridges, noise barriers, and tunnel structures. All design services are carried out comprehensively using the BIM methodology and also include optional services for subsequent planning phases (preliminary design, approval planning, and tender design).

Within Planning Section PA 1 Grafing–Ostermünchen, OBERMEYER is responsible for the design of the structural engineering works and tunnels. Key elements include the approximately 700-metre-long Filzental Bridge and the roughly 3,700-metre-long Salach Tunnel.

Within Planning Section PA 3 Innleiten–Kirnstein, OBERMEYER is responsible for the design of the structural engineering works, transport facilities, and selected tunnel components. The scope includes, among others, the approximately 8.5-kilometre-long Innleiten Tunnel between Innleiten (Stephanskirchen municipality) and Riedering, as well as the open-track section in the area of the operations station with passing loops near Holzen. Immediately before the A8 motorway near Rohrdorf, the roughly 13.9-kilometre-long Sattelberg Tunnel begins and concludes west of the Inn and the Inntal A93 motorway after passing beneath both.
