  Buses departing to Helsinki and Jyväskylä 30m
  
  If you need to catch a train at Orivesi train station (e.g. at 15:26), then please contact the organisers!
  
  The Jyväskylä bus was originally scheduled to leave at 14:45 to catch the 15:26 train, if needed. As there is no need for the stop at Orivesi, the plan is to leave at 15:00 continue directly towards Jyväskylä (i.e. no stop at the train station).
  
  The bus towards Helsinki is "ready for boarding" at 15:00 and will leave as soon as possible after. The bus will stop close to Kivistö train station in Vantaa (Keimola stop) and at Käpylä station on the way to Kumpula.
