The World’s Longest Rail Tunnel Implemented with ERTMS

Services we provided

Being the world’s longest rail tunnel with its 57 km, St. Gotthard railway tunnel is naturally included in the nationwide ERTMS implementation in Switzerland. Due to the potential maximum speed of 250 km/h, the Gotthard Base Tunnel must be fitted with the ETCS Level 2 for legal reasons. 

Overall, Ramboll has provided safety, interoperability and RAM consultancy support. In addition, Ramboll also provided documentation to the proposing consortium to demonstrate how the proposed system-design would fulfil safety, interoperability and the dependability (RAM). This comprised ERTMS signalling systems, train management systems as well as power systems. 

Upon completion, the implementation of the ETCS Level 2 will allow for monitoring the speed of trains over the entire route while generally improving and securing long-term safety. Ramboll also delivers project management, automation and energy projects from out permanent office in Switzerland.
