I found a
(Dutch) news article, which I've translated and summarised below:
Eurostar's version:
Eurostar requested an increase in Dutch border force staff at Amsterdam from 3 to 5 staff members (due to the capacity increase from 260 to 650 passengers per trains), by corresponce in June of 2024 (or December 2023 in
other sources), with increased staff to start from April 2025. This is at a significantly longer timeframe than the minimum required under the agreement for the border checks, which lists the minimum timeframe as 14 days. The minister was very slow to communicate and no meeting happened until April 2025, and the request was denied for at least all of 2025, and refuses to give any certainty for 2026. Eurostar pays for the border force, and offered to increase payments to finance the extra staff.
Ministry of Asylum and Migration (responsible for border force) version:
We have always been clear about what is and isn't possible. Any delays that may occur are Eurostar's fault for selling tickets before they had confirmed in writing that extra staff would be available. Eurostar is aware of the timeframe agreed in the original agreement for expanding border force capacity.
The Ministry of Asylum's position is confirmed by this statement on
the Dutch border force's website
Some relevant context for people less familiar with Dutch politics: Minister Faber is broadly perceived as highly incompetent; And the border force is currently overstretched due to a political decision to do more border checks at the borders with Belgium and Germany, with each location requiring at least 10 border force staff members. My personal experience of dealing with the Dutch government suggests that Eurostar's account is likely accurate.
Regarding the costs, the statement that Eurostar pays for the border force and Schiphol airport does not, has repeatedly been included in Dutch media (e.g., the article above, or
here), and at no point has the ministry denied it in their statements in the same articles. It is not mentioned in the border force statement above either, however it does mention that the provision of border officials at Eurostar stations is not according to the legal obligation that is present at Schiphol airport, but instead under an agreement between the ministry and Eurostar.
Dutch news articles have previously stated that airlines are charged for security at Schiphol, but that border force is covered by the government. Checking the official government budget, the income of the border force is so low that it can't be charging anyone other than Eurostar, with an income varying between four and eight million euros annually. Eurostar is reported to be paying in that range.
Do we know what the arrangements at St Pancras, Paris Nord, Brussels Midi and Lille Europe are?
Eurostar has stated that the situation as present in the Netherlands is unique, but I guess that doesn't help much figuring out what the situation in other countries is beyond that it is different from the Dutch one!
Was London - Brussels hourly all day all the way up until early 2020? Hopefully more Amsterdams will fill more of the current two-hour gaps.
There is plans to expand from 3 tpd currently to 5 tpd next year on London-Amsterdam, which will increase frequency for Brussels.
Through-tickets should really be sold with both the Eurostar and the ICE service though, to maximise the number of journey opportunities.
