I am flying from Berlin to Zürich and continuing my travel by train. I am considering booking a fixed-connection train ticket, which is available for a train departing 1 hour 3 min after landing. 

I have never been to Zürich Airport and don't know how large it is or how easy it is to reach the train station. So I have trouble calculating if there is a reasonable chance that I catch the train. What would be a rough estimate of the expected time needed to reach the train station, under following factors: 

- assume that the flight arrives roughly on time 
- I am an EU citizen, so shouldn't need to pass too many control points 
- I don't have checked luggage on that flight 
- I am flying with Swiss (do they get preferred slots close to the terminal, so the passengers don't need to wait for the bus?)
- I have a cheap ticket, so won't be able to leave the plane early  
- I can sustain a brisk walking speed 
- assume that nothing out of the ordinary happens (e.g. security pulling me out for questioning)
