BLS Rosshäusern Tunnel

Railway tunnel Technical facilities / equipment

Project description
The 2.1km long Rosshäusern tunnel is the centrepiece of the new Rossäusern-Mauss line and part of the double-track expansion of the Bern-Neuchâtel railway line.

In addition to the actual tunnel, there are technical buildings at both portals, which house the railway technology. In the middle of the tunnel, there is an emergency exit: a shaft about 45m deep with an elevator and stairs, which serves for self-rescue and evacuation of passengers in the event of an incident. EPRO TRAFFIC accompanied this extensive project already in the procurement phase by drawing up the specifications for the “Low Voltage” and “Data Networks” lots.

During the evaluation of offers from various railway technology providers, EPRO TRAFFIC graded specialist technical aspects. The mandate was extended by BLS. EPRO TRAFFIC was commissioned with specialist controlling and owner representation for the further phases planning, implementation, and commissioning. In addition, EPRO TRAFFIC coordinates the overall integration of the tunnel with BLS’s specialist services, especially with regards to data networks and control systems / alarm management.
