This is the wrong statistic! It doesnt matter how often you take the train, but how far you go. There is something called a passenger kilometer. Someone traveling one kilometer by train makes one passenger kilometer, 6 people on a train going 10 kilometers makes 60 passenger kilometers. The same can be done for other modes of transportation. The modal split (the right statistic) then shows how much each mode of transportation is actually used. Here you can find the statistic for each country of the EU: https://www.eea.europa.eu/data-and-maps/daviz/passenger-transport-modal-split-2#tab-chart_1

A few examples why modal split is better than frequencies:

• Environmentally CO2 is emitted per kilometer. Someone may bike a short distance everyday to work, but visits his parents who live far away every weekend by car.
• On the way to work someone could take the car and the train on the same commute.

The Netherlands is very much missing from this

I fully understand not wanting to use a train in Greece.

A probe into the tragedy would focus on the "chronic delays in implementing railway works, delays caused by chronic public sector malaise and decades of failure," government spokesman Yiannis Economou told reporters in Athens.

That said, I feel all European countries, maybe except of Switzerland, have failed to proper care for their rail infrastructure and missed the chance to convince more people to travel with trains instead of cars. :(

Here's the article this image arms to be based on, which includes many more counties.

Finland is missing

That looks like bullshit. Or it's at least missing some data. Czechia, by the very nature of being in the middle of Europe, we have the densest train network which in turn means our trains go even to the smallest of shitholes and it's very common to take a train somewhere.

What do European country are you from?

France, Germany, EU, Sweden

All are countries in the EU

As a train traveler in Bulgaria (absent from this statistic but present in the one posted in the comments), I can vouch for our low rates of train commute (still 3 times higher than Greece) The car culture is going strong with everyone using their own vehicle. A lot of places are barely reachable by bus and unreachable by train. It takes longer and there are delays. The security is questionable with creeps causing trouble fairly often, despite police always being present. It's rather dirty, the trains are mostly Soviet era. We can't talk about air conditioning, only open windows (which you prop open with an item that you're not afraid to lose) and scorching radiators.

Despite all that I love commuting by train. I can sit comfortably, stretch, walk around, use the (very poor) toilet if needed. I can cross stitch when creeps don't try to talk to me, I try to sit around grannies that take interest at most. It's cheap, you can go from the coast to Sofia in about 7 hours for 15 euros, half if you have a card. It's easier to talk with the person I'm traveling with. The scenery of rural Bulgaria is absolutely beautiful, and best of all - No motion sickness!

this seems to somewhat correlate with cold.

My country has 0 trains.
