Kindly advice if I need the supplement to travel to Breda from Schipol.
I have a NS flex and take the Direct train to Brussels without transferring at Rotterdam. I was charged on train once for not having the supplement, so my understanding is that I have to take the supplement even if I am not getting down at Rotterdam? Kindly confirm.
Also, when I tap on the red pole for supplement at Schipol do I need to tap out again? Asking since I have been marked as no checkout a couple of times.
