When you make a booking, even if the train times change your saved times in NSInternational never change. My train left 33 minutes earlier than shown in NSInternational and I got no notification: not in NSInternational , by email, or by text. BEWARE. (Compensation delays are taking 36+ weeks too)
Also, in the event your train actually is departing at the original time, notifications are only sometimes working. Track changes might not listed.
Thanks to NSInternational and Schiphol airport, my belief in the ability of the Dutch to organise things well is appropriately adjusted.
