Direct services will begin operating between Amsterdam Central and London St Pancras on December 15, when the 2020 timetable comes into effect.
Currently passengers must disembark at Brussels South station to clear security and immigration before continuing their journey to London. For London - Amsterdam passengers, security and customs checks take place before boarding at London St Pancras.
Under the new arrangements, these checks will take place at Dutch stations.
Netherlands Railways (NS) and Eurostar are working to complete facilities such as segregated platforms and waiting facilities, which will enable security and immigration checks to be transferred to Rotterdam Central and Amsterdam Central.
Despite the agreement, the Dutch government says a no-deal Brexit would complicate customs arrangements for direct services between the Dutch and British capitals. French National Railways (SNCF) warned in July that a no-deal Brexit could even result in the temporary suspension of Eurostar services.
Eurostar launched London - Amsterdam services in April 2018 and added a third daily train in June this year.
