Hi there, I need to stop in country of residence (Netherlands) before going on to the UK. Therefore once I leave I will have no outbound journey left. I understand that I can buy a separate ticket within the Netherlands to a “virtual” train station on the border (Dutch-Belgium), however 1) how do I know which virtual train station I will need to buy a ticket to? 2) how do I buy this ticket to the virtual station- is it just via the usual NS app? Thank you! (Also I can keep travelling outside of my country of residence once I’ve used my in/outbound right?)
