In the Helsinki area you can get information on local and regional routes, timetables and tickets from the Traffic information telephone number 0100-111 (€ 0,41/call + local call charge).
You can also use the YTV Public Transport Journey Planner, to check the available routes and transportation on the specific days and times. The Journey Planner can be found from the following URL: http://aikataulut.ytv.fi/reittiopas/en/
The new Finland Journey Planner launched by the Finnish Public Transport system can also be used to plan your journey.
"Journey.fi allows you to search for the best public transport connections between selected locations. At the moment the service provides door-to-door information on the following: all trains and all express buses in the Helsinki metropolitan area, and local traffic in Joensuu, Kuopio, Lappeenranta, Mikkeli and Tampere. In the future, more cities will be added to the service."
