Renfe shakes up timetables due to Garraf tunnel works: How will it affect your AVE, Avlo, and local services?

If you've tried booking a train to Barcelona in the last few weeks and noticed fewer services than usual, don't worry, it's not just you. Renfe has been forced to slash services (and completely shake up its operations) due to major works right in the heart of one of its busiest lines. The reason, as is often the case, is a set of improvement projects that are set to drag on for a while. We're talking about the work on the Garraf tunnel, that crucial link connecting the south with Barcelona, which since mid-March has turned into a major headache for both the operator and travellers.

Three months of works: Which Renfe lines are affected?

First things first, let's break down what's happening. The work on the Garraf tunnel isn't just a weekend fix; it's a significant project set to last three months, directly impacting the corridor connecting Zaragoza, Caspe, and Barcelona, and by extension, the entire high-speed and long-distance network that funnels through there. This means that both the flagship Renfe AVE and the budget-friendly Renfe Avlo services on the Madrid-Barcelona route have had to adjust their timetables, and in some cases, skip stops or combine with a replacement road service. And hold on, the Renfe Alvia services connecting the north (from Galicia or the Basque Country) with Barcelona have also had to shuffle their schedules.

The bus shuffle: Renfe's Plan B

To try and minimise the chaos, Renfe has laid on a comprehensive bus network to cover the worst-affected sections. Essentially, on some stretches where the track is completely closed, passengers have to get off the train, hop on a bus, and then board another train on the other side. Yep, you heard that right. It's a hassle, especially if you're travelling with luggage or kids. So, what are the alternatives? The company assures that overall travel times will stay roughly the same, though I'd venture to say that with a transfer involved, you should always factor in some extra buffer time.

• AVE and Avlo trains: Fewer direct Madrid-Barcelona services. Some trains are being diverted onto the conventional line through the affected section, leading to longer journey times.
• Renfe Alvia: Trains coming from the north (like those connecting with Bilbao or San Sebastián) are also facing delays and timetable changes to fit into the available slots through the works.
• Local services (Rodalies/Cercanías): While the focus is on long-distance, commuters on lines like Bilbao's Cercanías don't need to worry as the impact is mainly on the Mediterranean corridor. The same can't be said for Catalunya's Rodalies lines, which are also affected on the stretches near Garraf.

From Zaragoza to Barcelona: The hardest-hit route

If you live in Aragon or are planning to travel from Zaragoza to Barcelona, get ready. Renfe's overhaul is particularly intense on this route. 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 not quite the same. The company has promised clear information at stations, but you know how it goes: best to keep your phone charged and the Renfe website handy to check real-time train status, because the departure boards can be a bit slow to update.

From someone who's been riding the rails for decades

Look, I've been catching trains since I was a kid and I've seen it all: strikes, delays from breakdowns, works that drag on forever... This Garraf project is necessary, no doubt, but it's a pain. It's a pain because just now, when it seemed like Renfe Avlo was making high-speed travel more accessible and prices were becoming competitive, we hit this three-month bump in the road. The hope is that when the works finish at the end of June, everything will run better than before. In the meantime, it's time to arm yourself with patience, double-check those timetables, and if you can, avoid peak times when the transfers can get really clogged up. And if you've got a ticket for the next few weeks, don't rely on memory: jump on the Renfe website and check if your train's still running to schedule or if you're now one of the ones facing a bus transfer. Because, as I always say, with trains, better safe than sorry.
