Avlo vs. OUIGO: Which High-Speed Train Is Best in Spain?

When it comes to getting around with low-cost trains in Spain, the biggest difference between Avlo and OUIGO is how far their networks reach. Avlo, backed by Renfe, has the advantage of a much wider and more established route map.

It connects major hubs like Madrid, Barcelona, Zaragoza, Valencia, Alicante, Seville, Málaga, and Córdoba, plus a long list of secondary cities across northern Spain and the Mediterranean corridor. This means you can travel directly to your final stop without hunting for an extra transfer. For anyone heading to a smaller city or somewhere slightly off the usual tourist path, Avlo usually offers the smoother, more convenient option.

OUIGO, on the other hand, runs on a more limited, but steadily expanding, network. It focuses mainly on key high-traffic corridors, linking cities such as Madrid, Barcelona, Zaragoza, Valencia, Tarragona, Alicante, Albacete, Cuenca, Valladolid, Segovia, Murcia, Elche, Córdoba, Seville, and Málaga. The coverage is solid if you're travelling between major hubs or sticking to well-known routes between the centre, the east coast, and Andalusia. While OUIGO's network doesn't stretch quite as far as Avlo's, it continues to grow year by year, adding more destinations and strengthening its presence.

Avlo wins on sheer coverage and convenience, especially if you're exploring beyond Spain's biggest cities, while OUIGO keeps things focused but continues to push outward, making it easier over time to choose a budget-friendly ride.

Luggage can make or break a train journey, and Avlo and OUIGO handle it quite differently. Avlo allows passengers to bring a small handbag or backpack up to 36 × 27 × 25 cm, plus a medium cabin suitcase measuring 55 × 35 × 25 cm, and there are no weight limits on either piece.

If you need extra space, you can add a larger suitcase of up to 85 × 60 × 35 cm, for a modest fee. This can be done during booking or just before departure, which is especially useful for families, long trips, or travellers who simply like to pack more.

OUIGO's baggage policy is less flexible. The basic ticket covers one handbag of up to 27 × 36 × 15 cm and one cabin suitcase measuring 55 × 35 × 25 cm, but if you want to carry additional or oversized luggage, you must purchase the extra baggage option in advance or up to 30 minutes before the train departs.

XL luggage can weigh up to 25 kg and measure up to 2 metres total across all sides. Failing to book it ahead results in a €25 fee at the station, which can be an unpleasant surprise.

For passengers travelling light with just one bag and a cabin suitcase, both Avlo and OUIGO are fine. However, for anyone carrying extra items or bulky luggage, Avlo baggage allowance offers a more flexible approach with lower fees for additional baggage. Knowing the baggage rules before you travel helps you avoid hidden fees and ensures a smooth, stress-free journey on Spain's high-speed trains.

For passengers who value speed and simplicity, Avlo's vending machines and mobile bar work well. For those who enjoy a broader selection and a bit of service interaction, OUIGO's OUIBAR makes the journey feel more comfortable and engaging.

Spain’s high-speed trains aren't all the same, and the choice between Avlo and OUIGO affects your comfort and experience. Avlo uses 106 (Avril) and 112 series single-deck trains, equipped with reclining seats, power outlets at every seat, and air conditioning. Capacity ranges from 438 to 581 passengers depending on the model, providing a smooth, predictable ride across the country's main routes.

OUIGO, in contrast, operates Alstom Euroduplex double-decker trains, reaching up to 1,018 passengers. Travellers can select the "Sky" upper level or "Ground" lower level, and choose between standard or XL seats. XL seats are 33% wider, ideal for long trips, and the upper deck offers a fun perspective, especially appreciated by families with children.

Avlo delivers a consistent, no-fuss journey with reliable comfort, while OUIGO's double-decker design offers more seating options, higher capacity, and a unique onboard experience. Choosing between them depends on whether you prefer simplicity or extra features and space for your high-speed adventure.
