Took the train out of Helsinki airport the other day and it was a quick and easy experience. Signage is clear from the terminal to get to the trains. There are a couple very deep escalators to go down into the train station. Payment is made via the app. There are also payment islands in the middle of the train station. Payment can also be made by tapping the card reader once on board after selecting the zones and the quantity of tickets. The train into the city is 4,3 Euros with no airport surcharge unlike other cities and takes 38 minutes to get into the city centre. read more
