We took a train from our hotel to downtown Helsinki en route to the airport before leaving. These trains are fast and smooth and make very few stops. They do have a slower train that makes all the stops. They have 4 sets of tracks two in each direction. Lots of public transportation, trains, buses, and trolley's.
Train station in downtown Helsinki.
Modern buildings mixed with older looking architecture.
The town square was all being renovated so in a year or so it will all look very nice.
Jacob, this picture is for you. Several buildings had advertising on the roofs.
