Renfe overhauls timetables due to Garraf tunnel works: How do the AVE, Avlo and local train changes affect you?

If you've tried to book a train ticket to Barcelona in the last few weeks and noticed fewer services than usual, don't worry, it's not just you. Renfe has had to tighten its belt (and completely reorganise its operations) thanks to some construction work smack-bang in the middle of one of its main arteries. The reason, as is often the case, is a set of improvement projects that are dragging on longer than expected. We're talking about the work on the Garraf tunnel, that critical link connecting the south with Barcelona, which since mid-March has become a real headache for the operator and travellers alike.

Three months of works: Which Renfe lines are affected?

First things first, let's get a clear picture. The Garraf tunnel works aren't just a quick weekend fix; it's a significant project that will stretch over three months, directly impacting the corridor connecting Zaragoza, Caspe and Barcelona, and by extension, the entire high-speed and long-distance network that runs through it. 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 road replacement service. And, you'll want to take note, the Renfe Alvia trains linking the north (from Galicia or the Basque Country) with Barcelona have also had to do a bit of a shuffle.

The bus hassle: Renfe's Plan B

To try and minimise the disruption, Renfe has put in place an extensive network of replacement coaches covering the most affected sections. Basically, on some stretches where the track is completely closed, passengers have to get off the train, hop on a coach, and then board another train further along. Yep, you heard that right. A real pain, especially if you're travelling with suitcases or kids. But what are the alternatives? The company assures that total journey times will remain roughly the same, though I'd hazard a guess that with a transfer involved, you should always factor in a bit of extra time.

• AVE and Avlo trains: Reduction in direct Madrid-Barcelona frequencies. Some services are being rerouted via 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 experiencing delays and timetable changes to fit into the available slots through the worksite.
• Cercanías (Commuter trains): While the focus is on long-distance, users of the Bilbao commuter services don't need to worry as the disruption is exclusive to the Mediterranean corridor. However, the Rodalies de Catalunya lines are affected on the 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. The reshuffle by RENFE is particularly intense on this route. Trains that used to stop at towns like Caspe now operate a mixed service: part train, part coach. And as you can imagine, it's not quite the same. The company has promised constant updates 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.

A view from a long-time train traveller

Look, I've been catching trains since I was a kid and I've seen it all: strikes, delays due to breakdowns, works that go on forever... This Garraf project is necessary, no doubt, but it's a pain. It's a pain because just when it seemed like Renfe Avlo was making high-speed travel popular and prices were starting to look competitive, we hit this three-month hurdle. The hope is that once the work finishes at the end of June, everything will run better than before. In the meantime, it's time to arm yourself with patience, double-check your timetables and, if you can, avoid peak times when the transfers might get clogged up. And if you've got a ticket for the coming weeks, don't rely on memory: jump on the Renfe website and check if your train still has its original time or if you're now one of the ones who has to make the coach transfer. Because, as I always say, with train travel, better safe than sorry.
