We are planning a train ride from Vienna to Salzburg and are wondering whether it's worth splashing out on 1st class tickets. Does anybody if there are significant difference between the 2 classes? I recall seeing somewhere that there are 1st class compartments with panorama windows. Is this applicable to all trains? And if it is worthwhile? Is the journey from Vienna to Salzburg scenic?
I understand that there is no charge for children under 4. If that's the case, does the child get to have a seat too, or do they need to share it with the parent?
Many thanks for your help.
