> I was hoping for a list of shortest travel times between stations in Europe, as more of a thought/data experiment. Or put another way; which two train stations in Europe have the least distance between them?
That would not be very interesting. I live close to a train station that's less than 5 minutes (by train) away from the nearest other train station. The other train station is the city hub with many connections to other cities. There is nothing interesting about this connection, it simply replaces a 20 minute bike or bus ride. There are many such connections.
I assume if you only observe the data in isolation. But compiling that data would provide an image of where the density of stations are higher. Again, we can assume that's probably around the bigger cities, but until we actual lay out the data, we are just assuming. Maybe it'll prove the data right, but maybe it will reveal something we didn't expect. Testing the obvious sometimes lead to unobvious observations.
