France’s TGV (Train à Grande Vitesse) — marketed as TGV inOui for classic services and OUIGO for low-cost — is still Europe’s high-speed pioneer. This 2026 guide covers Paris hubs, Prem’s fares, seat rules, Lyria links to Switzerland, and how to book live TGV tickets on EuroRail Times.
What is TGV inOui vs OUIGO?
TGV inOui is SNCF’s full-service high-speed brand: café-bar, quieter coaches, flexible fare families, and through-tickets across much of France. OUIGO is the budget sister — cheaper seats, stricter luggage rules, and often secondary departure halls. Pick inOui for comfort and connections; OUIGO when price wins and you travel light.

Prem’s, Second vs First, and OUIGO fares
- Prem’s — cheapest inOui quotas; non-flexible; open ~4 months ahead (sometimes earlier on key lines).
- Second / First (inOui) — standard seats; First adds quieter coaches and a bit more space — see 1st vs 2nd class.
- OUIGO — rock-bottom prices; pay for large luggage and seat selection; arrive early for bag drop / boarding.
Friday evenings and Sunday returns Paris↔province sell out first. More tactics in our cheapest tickets guide.
Which Paris station?
- Gare de Lyon — Lyon, Marseille, Nice, Switzerland (Lyria), Italy-bound connections.
- Montparnasse — Bordeaux, Toulouse, Nantes, Brittany, Spain via Hendaye/Irun.
- Gare du Nord — Eurostar, Lille, Brussels corridor (not classic TGV Sud-Est).
- Est / others — Strasbourg, Germany (some TGV / ICE / Lyria partners).
Wrong station is the #1 same-day miss for first-time visitors — check the ticket PDF before you leave the hotel.
Reservations & Interrail
TGV requires a seat reservation (included in point-to-point tickets). Pass holders must still buy a TGV reservation — quotas are limited on popular trains. Budget €10–20+ per leg into Interrail maths; details in our Interrail 2026 guide.
On board
- Wi-Fi: Free on most inOui; variable speed.
- Power: Sockets at most seats on newer duplex sets.
- Bar: Café-bar on inOui; OUIGO has limited or no catering — pack snacks.
- Quiet zones: Look for silence coaches on longer runs.
TGV vs flying inside France
Paris–Lyon, Paris–Bordeaux and Paris–Marseille usually beat flying door-to-door once you add airport transfers and security. Full framework: train vs plane Europe 2026.

Practical FAQs
How fast is the TGV Paris to Lyon?
About 2 hours on the fastest services. Prem’s fares appear months ahead and vanish first on Friday evenings.

Yes. Point-to-point tickets include a seat. Interrail/Eurail pass holders must buy a separate TGV reservation.
Is OUIGO worth it?
Yes when the fare gap is large and you travel with cabin-size bags. Add fees for large luggage and remember the secondary hall / earlier boarding.
