I was search website for trains from Zurich HB to Airport, S2 and IR takes approx 12 mins for this journey. I want to ask what is S2 and IR are they different types of train services?
Which one will be better? Both are priced equal.
How much do we have to walk from train station to Airport departure building?
If I buy the train tickets in advance will it be cost saving or it will be same priced if I buy them on the same day at Zurich HB?
