Finnish transport is a wonderfull thing. I have been in Helsinki for only two weeks, but i think my good, stress-less relationship with its public transport is a thing that will keep on going strong.
Why you ask? Well let us compare the Dutch transportation system to the Finnish one shall we?
In the Netherlands, the people have to use the OV card if they are students, and buy a ticket at the machines. The trains tend to experience a lot of delay when the weather is bad, or the rails themselves are broken down, or sometimes there are simply not enough wagons to keep up with the rush hour. The times when every train leaves depends on where the train is going, but sometimes if you miss one train you might have to wait a whopping 45 minutes for the next one. In terms of the Dutch busses i cannot say too much, because i have not traveled with them often enough in my life, so i will leave them undiscussed for now, but the stations in for example Leeuwarden is in the open air and it can be a bit hard trying to find from where your bus will be leaving. But seeing as the station was being renovated before i left, perhaps it will be more clear when i am back.

Now the Finnish first of all also have a travel card, but everyone can buy one. You can also put money on it like the OV, but you can specify if you want to be able to travel to all areas in Helsinki, or just certain destricts. Otherwise it works about the same. It applies for all forms of public transport. However when you buy a ticket, it is a little different. Wheras the Dutch tickets are only valid between your starting and your end point, the Finnish tickets go by time. You can travel anywhere you want, as long as you are there within, say, two hours, or you will need another ticket. But seeing as you are able to buy a ticket in the bus itsself, or in the train as well, it is not that big an issue.

I have not seen many bus stations thus far of course, but i feel obligated to at least talk about the one i now use daily, namely the station located in Kamppi. The first time i saw the bus station i was amazed. First of all it was underground, which in hindsight makes sense i suppose, with the weather possibly turning so harsh here in the winter months. The second amazing part was that there was a long row of terminals, which all listed their end destination and what time it would leave. So there was no possible way of getting lost trying to find the right terminal! As long as you knew which end destination route your stop was, you're solid! Luckily for me, one bus's endstop is the Otaniemi campus, where i work, so it is very easy every morning. The busses all leave from a terminal, and the sheer amount of busses coming and going is amazing.

Another smaller yet amazing detail about the Finnish public transport compared to the Dutch one, is the time. I mentioned earlier that sometimes as a Dutchy you have to really haul ass to make it from, say, your bus to your train, and if you miss it you might be stuck for 45 minutes. Amazingly, no such thing in Finland. Every max 5 minutes there is a new metro or bus ready to take you to your destination. I have traveled in the London underground before, so seeing the metro being so timely was not that shocking, but the busses did surprise me. The drivers are super punctual and as soon as it is their time to leave, they have no qualms about just pulling out and driving off. But seeing as another bus arrives merely 5 minutes later, i find myself unable to care if it happens. It is very relaxing to just saunter up to your transport system in relaxed ease, and if you miss one, no big deal. It saves me a lot of stress and loitering around. The NS could definitly learn from this in my opinion!
The other small interesting thing about the Finnish transport, is less about the transport itsself, but the people in it. The first thing i had noticed was that everyone has their bag on their lap. At first i wondered why, but then i figured it was because of the floor being so wet. With everyone tracking in snow and it melting, the floor can turn pretty wet. And the Fins are very QUIET. Thus far, for two weeks, the people i heard talk in the metro of the bus i can still count on one hand. They don't need a stilte coupe here, cause every one is silent. They only talk on the phone or when they are in the transport with a friend, but even then it is so hushed you hardly notice. Quite perculiar, but not something i find myself minding very much!
