The intention in Digirail’s EKA track section is to use a radio network solution to communicate with trains by utilising commercial network connections. Digirail is in the process of collaboration with Finnish telecom operators to design a common disturbance map view that enables efficient train traffic.
Digirail has investigated the possibility of receiving disturbance information from the Finnish commercial telecom operators for the purpose of preventing traffic disruptions in rail traffic. The review work has been successfully completed, and in cooperation with three Finnish commercial telecom operators, it has been determined that a map view can be created to combine the disturbance information of the three telecom operators simultaneously.
“Information on planned and unplanned radio network disturbances from telecom operators has been successfully combined into one controllable entity. This is a unique concept that, to our knowledge, has not been implemented anywhere else. The desire to cooperate has been very enthusiastic among the telecom operators. This is a good example of how Finland’s digital transformation solutions are among the world’s best. Such solutions could not be innovated without the functioning cooperation we have experienced with the telecom operators”, says Simon Indola, Project Manager.
“The Finnish railway sector is undergoing something entirely novel. The system developed in cooperation with telecom operators will definitely generate interest, as the rest of the world is following closely how Finland succeeds in utilising existing commercial radio network connections to ensure data communications with trains. Building a designated 5G-level communications network for the sole use of railway traffic would cost hundreds of millions of euros”, Indola continues.
Potential disruptions in communications can be anticipated
Disturbance information provided by telecom operators and a jointly developed system are essential, as Digirail intends to use commercial radio networks for train communications. When the communications between trains and traffic control is transferred to radio waves, it is critical to ensure a continuous connection.
Disturbance information can be used to anticipate potential radio and communication disturbances, which will help in preventing traffic disruptions. It is important that traffic controllers are aware of possible disturbances or service interruptions so that they can ensure the safety of specific track sections.
“The major benefit of a common disturbance map view is that we can anticipate potential connectivity disturbances before the traffic controller issues moving authority to a driver. The system developed with telecom operators allows us to implement so-called proactive monitoring. The next step is to decide who will be responsible for monitoring connections and how it will be implemented”, says Simon Indola, Project Manager.
