OV Service Shops: public transport service centres NS is collaborating with other carriers in providing public transport service centres – ‘OVservicewinkels’ or service shops – at stations. Customers can go there for help with their queries about public transport travel. In 2016 we opened service centres in Tilburg, Utrecht (Jaarbeurs side), Alkmaar and Maastricht. In Venlo and Roermond, Arriva moved into the current Tickets & Service centres as well, turning them into a combined information desk. In Arnhem we extended the collaboration with Breng.
