"When it opens in 2016, the 57-kilometer-long Gotthard Base Tunnel (GBT) will form an important part of the European high-speed rail network, linking the north and south of the Swiss Alps and reducing travel time from Zurich to Milan from 3.5 hours to 2.5 hours. Within the engineering group Gotthard Base Tunnel South, which consists of three companies, Pöyry Infra AG was responsible for designing the GBT ventilation system. Pöyry Infra graduate engineer Reto Buchmann describes how he and his team used MATLAB based fluid dynamics models to determine how the system should be operated under normal, maintenance, and emergency conditions..."
