Automatic Functions AF
Train Traffic Control System Lötschberg Base Tunnel, Switzerland
The system Automatic Functions AF is the train control system of the Loetschberg base tunnel of the NEAT. The first operational use of this client/server based railway control system was in 2007, today it handles over hundred trains daily. The system takes advantage of the radio-controlled system of the ETCS/ERTMS Level-2 and uses it to realize a whole array of new functions, which are indispensable for a modern railway company.
With a total length of almost 35km, the Loetschberg base tunnel is one of the longest railway tunnels of the world. Special precautions had to be taken and different systems were installed to ensure the safety of passengers and personnel. Therefore the Automatic Functions AF also implements a set of functions which are specialized for such long tunnels.
The system is based on commercial off-the-shelf hardware and operating system.
