GDTsystemet

GDTsystemet is a proprietary digital communication system developed and implemented by the Swedish Transport Administration (Trafikverket). It serves as a critical infrastructure for the management and control of railway traffic throughout Sweden. The system facilitates real-time communication between train operators, traffic control centers, and other essential railway personnel.

The primary function of GDTsystemet is to ensure the safe and efficient movement of trains. It transmits vital information such as train positions, speed, route status, and potential disruptions. This data is crucial for maintaining traffic flow, preventing collisions, and responding effectively to incidents. The system integrates various sub-systems and technologies to provide a comprehensive overview of the railway network.

GDTsystemet replaced older, less advanced communication systems, offering enhanced capabilities for real-time data processing and improved reliability. Its implementation has been a significant part of Trafikverket's efforts to modernize Sweden's railway infrastructure and enhance operational efficiency. The system is continuously maintained and updated to meet evolving safety standards and technological advancements in railway signaling and control.
