Renfe adjusts schedules due to Garraf tunnel construction: AVE, Avlo, and commuter trains—here's how it affects you

If you've tried to book a train ticket to Barcelona in the past few weeks and noticed fewer departures than usual, don't worry—it's not just you. Renfe has had to tighten its belt (and completely reshuffle its operations) due to construction that has dug right into the heart of one of its main arteries. The reason, as often happens, is improvement work that's set to drag on longer than anyone hoped. We're talking about the intervention in the Garraf tunnel, that key route connecting the south with Barcelona, which since mid-March has become a real headache for both the operator and travellers.

Three months of work: which Renfe lines are affected?

First off, let's get a handle on what we're dealing with. The construction in the Garraf tunnel isn't just a weekend patch-up—it's a major intervention that will last three months, directly impacting the corridor linking Zaragoza, Caspe, and Barcelona, and by extension, the entire high-speed and long-distance network running through it. That means both the sleek Renfe AVE trains and the budget-friendly Renfe Avlo services on the Madrid-Barcelona route have had to tweak their schedules, and in some cases, drop stops or combine with a road alternative. And hold on—the Renfe Alvia trains connecting the north (from Galicia or the Basque Country) with Barcelona have also had to rework their maps.

The bus shuffle: Renfe's Plan B

To try and minimize the chaos, Renfe has rolled out a extensive network of shuttle buses covering the hardest-hit sections. Basically, on some stretches where the tracks are completely closed, travellers have to get off the train, hop on a bus, and then board another train. That's right, you heard it correctly. It's a hassle, especially if you're lugging suitcases or travelling with kids. But what are the alternatives? The company insists overall travel times will stay roughly the same, though I'd venture to say that with a transfer in the mix, you should always budget a little extra time.

• AVE and Avlo trains: Fewer direct Madrid-Barcelona frequencies. Some services are being rerouted along conventional tracks in the affected section, leading to longer travel times.
• Renfe Alvia: Trains coming from the north (like those connecting with Bilbao or San Sebastián) are also facing delays and schedule changes to fit into the available windows through the construction zone.
• Commuter trains (Cercanías/Rodalies): While the focus is on long-distance, users of Bilbao's commuter trains (Cercanías Bilbao) don't need to worry, as the impact is limited to the Mediterranean corridor. However, Catalunya's Rodalies lines are affected in sections near Garraf.

From Zaragoza to Barcelona: the hardest-hit route

If you live in Aragon or are planning to travel from Zaragoza to Barcelona, brace yourself. RENFE's reorganization is particularly intense on this axis. Trains that used to stop in towns like Caspe now offer a mixed service: part train, part bus. And as you can imagine, it's just not the same. The company has promised constant updates at stations, but you know how it goes: better keep your phone charged and the Renfe website handy to check real-time train status, because those departure boards can lag.

A view from someone who's been riding the rails for decades

Look, I've been taking the train since I was a kid, and I've seen it all: strikes, delays from breakdowns, construction that drags on forever... This work at Garraf is necessary, no doubt, but it stings. It stings because just now, when it seemed like Renfe Avlo was making high-speed travel more accessible and prices were starting to get competitive, we hit this three-month roadblock. The hope is that when the work wraps up at the end of June, everything will run smoother than before. In the meantime, it's time to arm yourself with patience, double-check those schedules, and if you can, avoid peak hours when the transfers might get clogged up. And if you have a ticket for the coming weeks, don't rely on memory: hit the Renfe website and confirm whether your train's schedule is holding or if you're now part of the bus-transfer crew. Because, like I always say, when it comes to trains, better safe than sorry.
