Hi Crystal,
>> so that means to say that when I bring my print at home tickets to the station, , the conductor while checking our tickets will Charge me for the difference of the tickets?
Your tickets will not be checked at the station. They will only be checked on board the train once the train is on its way. It will be too late to get off and get a Swiss Half Fare Card.
>> So I can still use my tickets right? Even if it is bought wrongly due to the half price issue? Will I be charged more than the regular price?
As far as I can make out from reading bureaucratic German, travelling on a half-fare ticket without a Swiss Half Fare Card will result in a fine of CHF 70 for a first offence, CHF 110 for a second offence and CHF 140 for each subsequent offence.
Why waste that money and spoil your holiday mood with such aggravation 😉
Buy your Swiss Half Fare card before you board any trains!
Mind you, I did something similar many years ago, when I was travelling with a Eurail Pass between Luzern and Chur via Göschenen and Andermatt. For the sector from Göschenen to Disentis, you needed to buy a supplementary ticket, which I did not know about at the time.
I made it from Göschenen to Andermatt without a ticket check, but at Andermatt my ticket was checked and I was informed it was not valid. However, as the train did not have a conductor, it was the driver checking my ticket, so the train had not left the station.
The driver kindly took me to the ticket machine on the station platform, and waited while I bought my ticket, and the train did not leave until I reboarded it!
However, this was low season at a small station, and very few passengers were on the train. In my carriage there were only two of us! I would not count on such kindness in high season on a mainline train that is already underway on its journey 😉
