ABSTRACT

The paper discusses the implementation of new, innovative, fully electric “Automated Service Vehicles” (ASV), designed for the operation as standalone vehicles or in train formation, serving as the logistical backbone for a 25km long mechanical excavation. These vehicles are used to supply the Tunnel Boring Machine with materials and carry out various other versatile logistical tasks. The project involves the construction of a 4,2m bored diameter diversion tunnel in the Kühtai area in the heart of the Tyrolean Alps, which will be used to collect water from the Stubai Glacier area for the Kühtai pumped-storage power stations operated by TIWAG. The paper provides an overview of the project’s tunnelling challenges and gives an insight of the Automated Service Vehicles technology. It also covers the experience gained operating these innovative, battery powered, fully electric vehicles, which are utilized flexibly, both as individual units and in various train configurations. Using a battery as power source ensures a CO2 (carbon) neutral operation, achieving significantly lower energy cost compared to Diesel powered vehicles. Furthermore, the ASV is prepared for a fully automated operation.
