The demand for public mass-transit transportation services is growing continuously. However, passenger capacity can seldom be expanded as generously as would actually be necessary. To continue to ensure the smooth running of mobility systems, on-track effectiveness and efficiency must be improved. The solution here is automation. With automation, the capacity of a metro line can be increased by up to 50 percent. Automated metro systems make it possible to realize short headway times of 80 to 90 seconds. Optimized acceleration, traction and breaking processes consume less energy. Depending on the degree of automation, power consumption can be reduced by up to 30 percent while simultaneously increasing train punctuality. On the basis of line data, the system calculates exactly how and at which point a train has to be accelerated and braked for it to arrive at the next station on time. The Siemens solution, Trainguard MT, is the most widely used system in the world today and is deployed by more than 25 metro operators, such as in São Paulo, Barcelona, Algiers, Paris and Guangzhou.
