The train station at Helsinki airport is really a welcome addition to airports transport options. The easy connection to central Helsinki is a really great improvement from the oft delayed buses and expensive (and often lacking in numbers) taxis.
The entrance is conveniently located in between T1 and T2 (so no need to walk outside any longer) and while escalators are jot fully operational the elevators are fairly fast. The station is clean and neat and the trains modern and spacious. I also really appreciate that it is possible to use the local travel cards so a cheap option to get into town.

It’s brilliant that the Helsinki Vantaa airport now has a train connection to the Helsinki central station — but beware that (currently?) the walk between the airport and train station is certainly not a few hundred metres like the signs states but more like a 2 km walk outdoors. If you have a lot of luggage that is pretty inconvenient. Once you reach the train station (which is very modern and fresh) you should know that the walk is far from over, you have to go down 5 (!) escalators, unless you opt for the elevator. And then walk in a long long long culvert before you finally reach the platform.
The comfortable ride into the city takes about 45 minutes and costs around 10 euros (Nov 2015).
The ticket machine on the platform didn’t work — and why it’s only one machine and situated at the far end of the platform is a mystery! — and never mind about the digital signs in the train windows that says ‘ticket sales’ resp ‘no ticket sales’ because the train staff sells tickets.
Unlike the train to and from Arlanda airport in Stockholm this train also works as a commuter train ring line so be prepared for a lot of stops along the way. But still, a train ride is a really convenient and comfortable way to travel to and from airport and city centre. Even if the long walk to get there is less so.

This is a new station on the Helsinki ring line that opened in summer 2015. It’s so new that it’s perfectly clean and spotless. Both tracks feature dramatic murals, as shown in my picture.
As of the time I write this (early September 2015) they have yet to open a direct passageway to the airport terminals. As such, it’s a very long trip from the station platforms to the terminals themselves. First, the station is incredibly deep. So deep, in fact, that you need to take at least three long flights of escalators up or down, so save some time and go straight for the elevators. Then, once you reach ground level, it’s a 450m walk to T1 and a 750m walk to T2, The ground-​level signs that have been put up by the airport aren’t well-​lit at night, and the walk involves twists and turns through underpasses and the airport parking garage, without any moving walkways.
According to the HSL website, the direct connection from the platforms to the terminals is scheduled to open in the fall of 2015, which should make things somewhat smoother. Nevertheless, it’s a marvel to look at how much effort and expense was spared in digging such a deep station while you’re making your way up to, or down from, ground level.
Although the Finnair buses to Helsinki central station are also a nice, comfortable option to take into central Helsinki, the rail line may be more convenient if you’re headed to any of the stations on the ring line between the airport and Helsinki central station. There are at least 10 stations in between, trains stop at every single one, and there are only 2 trains an hour after 23.00, so if you’re coming in late to Helsinki, the Finnair bus is still the faster, more frequent way to go.
