<<"I’ve managed to book my train back, but still no luck on the Basel to
interlaken trains. Would this be one that my dad can get at the station?
He’s not a well seasoned traveller so want to make it all as easy as I
can for him =)">>
At the counter, in German, French, Italian or English.
Or, from a ticket machine in the same languages.
The counter would be simplest and easiest, and they are used to foreign travelers. They may have a short line of purchasers, so if he wants to try the machines, they are quite easy.
You start by choosing a language on a touch screen (English, French, German or Italian) . The first screen will offer tickets from Basel ( if that is where he is; it displays the current station name) and lets you pick from some typical destinations, or type in a name on a touch screen, which offers a narrowing list of choices as you type.
Then you pick first or second class ( second is quite all right) and it tells you the cost. You can pay with paper money or credit cards...their are slots for both. If you give it too much paper money, it will give you change. That is one way to get a few Swiss coins in his pocket.
Here is a not terribly useful description:
with a video of sorts linked on on that page. Unfortunately, it is in French. On the earlier version of the website, they used to have a step-by step illustration. Maybe one of the moderators knows how to find it:

Actually, the machines are quite easy for simple tickets such as Basel to Interlaken. (Make sure he knows if it is Interlaken Ost or Interlaken West). But, the counters are easier.
