I assume you're referring to the Swiss Half Fare Card
and 50% discounted train tickets? In that case you can buy discounted tickets through sbb.ch
. They'll be valid for any train as long as you don't book seats for specific trains. Your parents would be bound to a schedule (at least per day, not the exact time) and can't change their plans this way. A Swiss Pass
would be easier if they prefer maximum convenience: no tickets required, and still the option to change plans, e.g. according to the weather.
I hope this helps you out!
