If you’ve received Eurostar or Thalys train tickets and they appear to be incomplete—don't worry. The tickets you’ve received are valid for your entire journey. Your ticket will have either “Any Belgian Station” (ABS) or “Any Dutch Station” (ADS) written on it. Occasionally both terms will be listed for certain itineraries.
Whilst you have chosen a specific route and departure time for your journey, only the Eurostar /Thalys ticket is for a fixed departure. The rest of your itinerary is flexible. The travel times in your confirmation email are only guidelines for your convenience.
With an ABS/ADS ticket, you can complete your journey with any train expect for high-speed services such as Thalys. This is why “Any Belgian Station” or “Any Dutch Station” is printed on your ticket and not the specific journey you selected on Omio.
