Tunnels are built and equipped on the basis of the most up-to-date and safe technologies and constructions

Tunnels are created wherever local conditions do not permit an efficient road or rail routes. They connect people by shortening travel times significantly, protect man and nature from noise and exhaust fumes and make remote areas accessible.

The safety standards for tunnels are regularly reviewed and adapted to the latest findings. New tunnels will be built and equipped on the basis of the most up-to-date and safe technologies and constructions, while older tunnels will have to be upgraded.

Tunnel automation with an end-to-end portfolio

ABB offers a portfolio of higher-level control systems (SCADA) which act on top of the local ABB PLC-based architecture. All technical subsystems and field devices of the tunnel system can be controlled and monitored from one or several central locations.

An end-to-end portfolio with a high number of scalable products and options, from the field layer right through to the management and visualization layers saves significant engineering time and money, while at the same time ensuring a highly available, safe and future-proof tunnel system.
