The government has assigned the main responsibility for the deployment of ERTMS in Sweden to Trafikverket (Swedish Transport Administration). This assignment includes accounting for and presenting the costs of the global project and outline the benefits for infrastructure owners and users of the railway. The signalling system is an important part of the railway system that contributes to safety and also enhances the possibility to organize traffic for better use of capacity on the railway. Today a number of different signalling systems are used throughout Europe. Trains that are crossing borders therefore have to be equipped with several signalling systems and the driver of the vehicle must be trained to use any one of them. ERTMS is a common European signalling system aiming at facilitation of border crossing traffic and replacing existing systems with a new generation of Control Command system. The current signalling system in Sweden, as in Norway, is ATC (Automatic Train Control).
