Traffic control is the responsibility of traffic controllers who have undergone training specified by Trafi and obtained a traffic controller’s qualification. In addition to the control of rail traffic, the traffic controllers’ tasks include securing access paths, issuing permits for shunting and securing track work and issuing permits for them. The traffic controllers are also responsible for managing traffic anomalies and exceptions together with various interest groups, such as the Finnish Transport Agency’s Rail Transport Centre, the rescue authority and other operators. In 2016, 81% of Finrail's staff worked in traffic control.
Traffic control is centralised into control service centres, which are located in seven localities: Helsinki, Tampere, Seinäjoki, Oulu, Joensuu, Pieksämäki and Kouvola. In addition to these larger control service centres, traffic is controlled also at separate points in eight localities.
Traffic is controlled around the clock, every day of the year.
