In the field of rail transport technology, the European Train Control System is a signaling and control system widely used in many European countries to control trains from a specific control center. The train control system of a line on which ERTMS/ETCS is used must perform all monitoring and control processes perfectly and fully automatically. Elements such as the switch operating system, signals and axle counters should also be easy to maintain and constantly in operation. AYESAŞ is characterized by its expertise in the development of EVC and DMI, two of the ERTMS system units.
