Train services are currently suspended on the direct line between Kerava and Lahti as a result of a malfunction in the traffic management system, as reported by Fintraffic's Rail Traffic Centre. This disruption has necessitated a deviation for long-distance trains, which are now being rerouted from Lahti through Riihimäki to Helsinki and vice versa. The Z-train services in particular have been halted indefinitely between these two points due to the ongoing issues.

The traffic control system problem has not only caused delays but has also left many passengers uncertain about when normal services will resume. No timetable for repairs has been issued at this time, meaning that commuters and travelers are advised to seek alternative routes or transport options until further notice. Public transport authorities are working to manage the situation and provide updated information to affected travelers.

As the traffic management failure continues without a known resolution timeline, the impact on daily commutes and long-distance travel could be significant. Passengers are urged to check for updates frequently, as the situation may evolve.
