1. The 520 Ceiling and the 2026 Count

The ministry and ProRail use a yearly performance ceiling of 520 “impactful” or “high-impact” disruptions (in Dutch coverage: grote storingen / impactvolle storingen). Exceeding the threshold can result in a financial penalty under the performance agreement.

Sources for the historical figures include RTL Z and government correspondence for 2022–2025, while the 31 August 2026 tally and 508–573 forecast were reported on 10 September 2026.

NL Times, citing AD, reported that ProRail had planned measures to reduce future disruption numbers and referred to an internal target of 459. Van Velthuizen’s comment to AD, reported by NOS, was that 2027 is also expected to exceed the 520 limit.

2. Causes ProRail Listed

NOS, citing ProRail, reported several causes behind the 2026 disruption count.

Technical failures were a major category, including the cable-duct fire near Rotterdam Stadion on 29 June 2026. A problem in a feeder cable caused a short circuit and fire. Rail traffic between Rotterdam and Dordrecht was disrupted for more than a week, while the high-speed line between Rotterdam and Breda was also affected.

Dry weather and heat were also cited. Three weekends of heavy thunderstorms in May and June produced sixteen large disruptions. Snow and frost in January produced twelve disruptions that counted toward the annual total.

Van Velthuizen told AD, as reported by NOS, that the network is becoming busier, meaning that a single infrastructure failure can have a larger impact. Extreme weather was also identified as an increasing factor.

Earlier reporting on the 2025 disruption file also identified copper theft, collisions with people or vehicles, points failures, overhead-line problems, signal failures and weaknesses in the maintenance market.

3. ProRail and NS: Who Does What

A ProRail performance penalty is separate from passenger compensation. If your NS journey is delayed, you use NS’s compensation procedure where the NS conditions apply.

4. Geld Terug bij Vertraging

NS publishes the current Geld terug bij vertraging (GTBV) rules on its website. The exact compensation depends on your ticket or subscription and the length of the delay. :contentReference[oaicite:2]{index=2}

For ordinary NS services, compensation generally starts at 30 minutes of delay. For Intercity direct and certain HSL services, compensation can start at 15 minutes. Claims normally need to be submitted within three months of the journey. :contentReference[oaicite:3]{index=3}

NS says there is no compensation when the calculated amount is below €2.30, when a longer journey time was already announced in advance, when another carrier caused the delay, when there was no valid ticket, or in certain listed force-majeure situations. :contentReference[oaicite:4]{index=4}

Important: The detailed NS compensation table used for the subscription-specific amounts was last marked 10 December 2025. The general GTBV rules remain published by NS, but readers should check the live NS compensation table before relying on a specific euro amount.

A claim is assessed using journey and check-in/check-out information. NS says claims can normally be submitted up to three months after the journey. :contentReference[oaicite:5]{index=5}

5. What Changed on 4 September 2026

NS published revised Algemene Vervoervoorwaarden (AVR-NS) effective 4 September 2026. :contentReference[oaicite:6]{index=6}

The most important change for passengers concerns strikes:

• The strike compensation provision in Article 6.4 was simplified to one main route: Geld terug bij vertraging (GTBV).
• The previous possibility of claiming up to €25 per person per day for alternative transport without checking in was removed.
• Passengers can still receive compensation for eligible delays during a strike, generally through GTBV and normally after checking in.

NS explicitly says that the alternative-transport reimbursement was removed from 4 September 2026. :contentReference[oaicite:7]{index=7}

A national public-transport strike took place on 9 September 2026. NS services were heavily affected, although the Airport Sprinter between Amsterdam Centraal, Schiphol and Hoofddorp continued to operate.

For journeys affected by the strike, passengers should use the rules that were in force on the date of travel.

6. Amsterdam Centraal–Weesp, 12–14 September

The planned Amsterdam Centraal–Weesp closure is scheduled engineering work rather than an unexpected disruption.

Work is planned from Saturday 12 September at 05:00 until Monday 14 September at 05:00, with work taking place at multiple locations along the corridor.

Passengers should expect changes to normal train services and should check the NS Reisplanner before travelling.

Important for compensation: planned engineering works that were announced in advance are generally not treated as a normal delay for GTBV purposes. NS’s conditions state that a longer journey time announced at least one day before the journey is not considered a delay for the GTBV calculation. However, if an additional unexpected delay occurs on top of the planned disruption, the circumstances can be different. :contentReference[oaicite:8]{index=8}

Always check the current NS planner because engineering schedules can change.

7. How to Check Before You Travel

The NS Reisplanner and NS app show the current timetable and alternative travel options, including buses replacing trains.

ProRail publishes information about infrastructure disruptions and planned works.

For an NS compensation claim:

1. Check your journey details and the actual delay.
2. Use Mijn NS or the appropriate NS claim form for your ticket.
3. Keep your check-in and check-out information where applicable.
4. Submit the claim within three months of the journey.

NS states that the GTBV claim deadline is three months after the journey. :contentReference[oaicite:9]{index=9}

International tickets such as Eurostar, ICE and Nightjet can be subject to the conditions of the operator that sold the ticket. Do not automatically apply the domestic NS compensation table to the entire international journey.
