I am helping a friend to plan a trip in the Netherlands. He is 68 years old. Is there some discount on the train like in Belgium?
Not really, at least for NS (the main operator in the country). As far as I know, the only things seniors can get are
- 7 day travel passes (called “Keuzedagen”), if they already have an Altijd Voordeel or Dal Voordeel discount card. You can't buy a single day travel pass at the discounted price, you have to buy 7 of them and you need to have a yearly discount card to benefit from the offer (it's not valid with a monthly discount card).
- Discounted prices on passes like Dal Vrij or Weekend Vrij. Those are also yearly passes.
None of this seems relevant for visitors and, in fact, the info is apparently not even available in the English-language part of the website.
There are a few other train operators, mostly in the north and east of the country but I don't know about those.
