Low-cost high-speed trains in Europe

Ouigo, Avlo, Iryo and friends — budget high-speed rail, and the catches.

Europe's high-speed rail market has genuinely opened up to budget competition over the past decade, and fares on routes like Paris–Lyon or Madrid–Barcelona can now undercut the legacy operator by a wide margin if you book the right brand at the right time. The trade-offs — stricter luggage limits, fewer amenities, and sometimes a secondary station rather than the city centre — are real, but manageable once you know what to expect from Ouigo, Avlo, Iryo and Italo.

Ouigo: SNCF's no-frills TGV

Ouigo is French operator SNCF's own budget brand, running on the same high-speed lines as the mainline TGV but stripped back: fixed non-reclining or limited-recline seating in standard fares, no complimentary at-seat service, and strict luggage rules (more below). It launched in France in 2013 and has since expanded to Spain as Ouigo España, running budget high-speed services from Madrid to Barcelona and Valencia. Fares can undercut the standard TGV or AVE by a wide margin if booked well in advance, though flexibility is minimal — tickets are typically tied to a specific train with little to no changes allowed.

Avlo and Iryo: Spain's budget and rival brands

Spain's high-speed market opened to competition in 2021, and two brands emerged alongside incumbent Renfe. Avlo is Renfe's own budget offshoot, running no-frills AVE services primarily on the Madrid–Barcelona corridor and a growing number of other routes, with fares that regularly beat both Ouigo España and standard AVE tickets when booked early. Iryo, a joint venture involving Trenitalia, competes on the same corridors with a slightly more comfortable standard fare tier than Avlo, sitting between full-price AVE and the strictest budget brands. See our Spain by AVE guide and Spain by rail guide for how all of Spain's operators now fit together.

Italo and Trenitalia's cheaper fare tiers

Italy has had genuine high-speed competition for longer than most of Europe: private operator Italo (NTV) has run alongside state operator Trenitalia's Frecciarossa services since 2012, and the rivalry has kept fares on routes like Milan–Rome and Rome–Naples competitive even without a dedicated ultra-budget brand. Both operators offer tiered fares — Trenitalia's cheapest Frecciarossa "Standard" or "Super Economy"-style tickets, and Italo's equivalent lower tiers — that are non-refundable and non-changeable but considerably cheaper than flexible fares. Booking early is what actually gets you the low price here, more than choosing one operator over the other. Our Trenitalia vs Italo guide compares the two head to head.

What you actually give up for the low fare

The cheapest tickets across all these brands share a pattern: they're tied to one specific train and date with little or no flexibility to change or refund, seats may not recline as far (or at all) compared with the standard mainline service, and complimentary food or drink is rare — bring your own or budget for the onboard trolley. None of this is a dealbreaker for most journeys, but it does mean a low-cost booking is a genuine commitment, not a flexible option to hold and change later the way some standard fares allow.

The luggage catch is the one that actually trips travellers up. Ouigo, in particular, enforces strict luggage size limits on its cheapest fares and can charge a real on-the-spot fee for oversized bags that don't fit its stated dimensions — a much stricter policy than the mainline TGV. Avlo applies similar limits on its budget tickets. Check the exact size allowance for your specific fare before you travel, not just the headline price, especially if you're carrying anything larger than a standard cabin bag.

Which stations you actually arrive at

Some budget services use secondary stations rather than a city's main terminus — Ouigo, for instance, has historically run some Paris departures from Marne-la-Vallée or Massy rather than Gare de Lyon or Montparnasse, both well outside the centre. That's not universal across every route or timetable, but it's exactly the kind of detail that's easy to miss when comparing fares by price alone. Always check the actual departure and arrival station printed on your ticket, not just the city name, and factor in the extra transfer time and cost if it isn't the main central station.

Booking tips to get the lowest fares

All these brands price dynamically, much like airlines: the earliest bookings on a given departure are the cheapest, and prices climb steadily as the train fills. Booking a month or more ahead typically secures the lowest available fare, and comparing a few adjacent departure times on the same day can reveal a meaningfully cheaper option even on a popular route. See our guide to how far in advance to book European trains for the general pattern across the continent, and our high-speed trains in Europe guide for how the whole network, budget and mainline, fits together.

Frequently asked questions

Is Ouigo the same train as a regular TGV?

It runs on the same high-speed infrastructure and often similar rolling stock, but with a stripped-back fare product — less flexible tickets, tighter luggage limits, and sometimes departures from a secondary station rather than SNCF's main Paris terminals.

Which is cheaper in Spain: Avlo or Iryo?

Avlo is generally the cheapest of Spain's high-speed brands on its budget fares, with Iryo typically sitting a step above it and closer to standard AVE pricing, though the exact gap varies by route and how far ahead you book.

Do budget high-speed trains require seat reservations?

Yes — like all high-speed services in France, Spain and Italy, your ticket is tied to a specific seat on a specific train, so there's no turning up and boarding the next departure the way you might on a slower regional train.

What happens if my luggage is too big for a budget fare?

You risk being charged an on-the-spot fee, particularly on Ouigo and Avlo's cheapest tickets, so check the stated size limits for your specific fare before travelling and pack accordingly if you're near the threshold.
