SNCF G30: the 30-minute guarantee

G30 is the name SNCF gives to its delay compensation guarantee: the Garantie 30 minutes. That is the name the rule exists under, and that is why this page is called what it is called.

A delay leaves two different traces, and they do not do the same job. The scale belongs to the carrier. Here, the records preserve reported times without confirming what happened.

What the official rule says

What follows is taken from the SNCF Connect help page «Retard de votre train et remboursement», read on 19 August 2026. It is here to orient you, not to settle anything: the carrier's own page is what counts, and a commercial rule can change without notice.

Services covered: domestic TGV INOUI, international TGV INOUI, INTERCITÉS with or without compulsory reservation.

The threshold: an arrival delay of 30 minutes or more.

The scale, as a share of the ticket price:

• under 30 minutes — no compensation
• 30 minutes to 2 hours — 25%
• 2 to 3 hours — 50%
• over 3 hours — 75%

The form: the refund comes as a voucher. A bank transfer is possible only for a delay of more than 60 minutes.

The deadline: the claim must be filed within 90 days.

The claim is filed with SNCF, using your file reference, through the dedicated form.

These points were read on the SNCF Voyageurs page «En cas de retard», on 31 October 2026.

What we do not copy here

The minimum amount below which nothing is paid is not stated on the official page we read, so we do not repeat it. The cases of automatic compensation and the detailed procedure are not repeated either. An approximate rule about money does more harm than no rule at all. They are on the carrier's site.

G30 or the European regulation: two thresholds, two scales

Two rules exist for a train that arrives late. They do not share the same threshold.

• SNCF G30: from 30 minutes. 25% of the ticket from 30 minutes to 2 hours, 50% from 2 to 3 hours, 75% beyond 3 hours. It covers domestic and international TGV INOUI and INTERCITÉS. Source: SNCF Connect, read on 19 August 2026.
• Regulation (EU) 2021/782, article 19: from 60 minutes. 25% of the ticket from 60 to 119 minutes, 50% from 120 minutes. It applies to every operator. Source: EUR-Lex.

The European regulation sets a minimum, and SNCF's guarantee starts earlier. See also our guide on European rights when a train is late.

A worked example with an 80 euro ticket

The price is made up for the example. Only the percentages come from the texts above.

• 25 minutes late: G30, nothing (0 euros)
• 45 minutes late: G30, 25%, that is 20 euros
• 2 h 30 late: G30, 50%, that is 40 euros
• 3 h 15 late: G30, 75%, that is 60 euros

For an 80 euro ticket, the European regulation gives 20 euros from 60 minutes and 40 euros from 120 minutes. The real amount depends on your ticket and fare: the operator calculates it.

Before you file a claim

• keep your file reference and your ticket
• note the train number, the date and the actual arrival time at your final destination
• check that your train is a covered service (TGV INOUI or INTERCITÉS)
• file the claim with SNCF, using its form: the deadline is 90 days, the operator's page gives the documents to attach (SNCF Voyageurs, in case of delay)

Our train record can help you recall what was announced. It does not replace SNCF's decision.

If your train is not covered

TER, Transilien and other services are not part of the G30. The European regulation may apply: see the guide on European rights. During a strike, see SNCF strike: your rights and the current strikes page.

What this site does

This site stores the available reported times and delays with their timestamps. These records can contain forecasts or scheduled times. They confirm neither the train's passage nor its final arrival delay.

What this site does not do

Compensation is a contractual relationship between the passenger and the carrier. It depends on the ticket, the fare, the reason for the delay and the conditions of the service concerned. None of those things are in a public feed, so none of them are here.

In practice: the claim is filed with SNCF. This site has neither your file nor the power to open it.

Why say it this plainly

Because a site that suggests otherwise wastes your time at the moment you have the least of it. A record can support a claim. It does not replace one, and it is not worth an official document from the carrier.

The threshold we show, which is not the G30 one

On this site, a train counts as on time below 5 minutes of delay, and heavily delayed beyond 15. Those two numbers have nothing to do with the 30 minutes of the G30: they classify reported delays without measuring confirmed arrivals or determining compensation. A percentage without a threshold means nothing: depending on the threshold you pick, the same network looks excellent or poor.
