Spain’s Low-Density Railway Lines Get a Boost: New Signal System Opens the Door to Hidden Tourist Gems

Published on November 25, 2025

For those seeking an authentic Spanish experience away from the crowds, Spain’s lesser-known regions are about to become much more accessible. A pioneering rail project, spearheaded by Alstom in collaboration with Adif (Spain’s national rail infrastructure company), is set to revolutionise train travel across the country’s low-density secondary railway lines. The initiative will not only improve the efficiency and safety of Spain’s regional railways but also significantly boost tourism by providing easier access to the country’s most picturesque and unexplored destinations.

In a bid to modernise rail travel, particularly on less-busy routes, Alstom’s state-of-the-art signalling technology has been introduced to Spanish regional railways. This system, known as the European Rail Traffic Management System (ERTMS), is set to bring the benefits of high-speed train networks to secondary lines. The ERTMS technology is designed to make trains safer, more reliable, and ultimately more attractive for both domestic and international travellers looking for alternative ways to explore Spain’s stunning countryside.

A New Era for Rural Tourism in Spain

Spain is home to some of Europe’s most beautiful, yet often overlooked, landscapes and towns. With rail travel increasingly becoming a preferred mode of transport for tourists, modernising secondary railway lines presents a golden opportunity to unlock these hidden gems. In fact, Spain’s official tourism website already highlights the significant role of rail in connecting visitors to remote and culturally rich regions. From the vineyards of La Rioja to the medieval towns of Castile, and the coastal serenity of Galicia, Spain’s quieter regions will soon become more accessible thanks to these upgraded rail systems.

This new signalling technology allows for the use of satellite sensors and public telecommunications networks rather than traditional, expensive rail communications infrastructure. This upgrade reduces the need for extensive trackside equipment and opens up remote train services to a wider audience, making travel to rural and lesser-visited parts of Spain easier and more affordable. It also means trains can operate more efficiently, with better safety features and smoother journeys for tourists hoping to explore Spain beyond the popular tourist hotspots.

Boosting Local Economies with More Visitors

While the main benefits of this project are apparent for tourists, local economies in these quieter regions stand to gain just as much. With improved rail access, smaller towns and villages that previously struggled to attract tourists will now see more foot traffic. For local businesses, this could mean a surge in visitors to local shops, restaurants, and attractions. It’s an opportunity for communities to grow their tourism sector while still maintaining the charm and authenticity that sets them apart from overcrowded cities.

The Spanish government has long recognised the importance of sustainable tourism as a driver for rural development. By providing tourists with reliable rail links to more regions, the government hopes to distribute tourism more evenly across the country. This shift is expected to help alleviate overcrowding in major cities, allowing Spain’s smaller towns and natural wonders to receive their fair share of international attention.

A Seamless Travel Experience for Tourists

One of the most exciting aspects of the new system is the potential for a more seamless travel experience. Currently, tourists often face challenges when travelling to Spain’s rural areas due to infrequent or unreliable trains. The introduction of ERTMS on low-density lines promises to change that. Tourists will be able to hop on trains that run more regularly, safely, and efficiently, making it easier to enjoy a spontaneous day out to a quaint town or a countryside retreat.

The improved infrastructure will also likely encourage more tourists to plan longer stays in rural Spain. It’s not just about getting from one city to another; it’s about taking time to explore the many hidden gems the country has to offer. Whether it’s the rolling hills of Andalusia or the charming fishing villages along the Mediterranean coast, tourists will now have the means to access Spain’s untouched beauty with ease.

The Road Ahead: What Tourists Can Expect

While the project is still in its early stages, the first phase of testing has already begun on the La Asunción Universidad to Guardo line in northern Spain. The rollout of the new system is expected to continue into 2026, with more lines gradually being upgraded to benefit from this innovative technology. For tourists planning trips to rural Spain in the coming years, this is a game-changer.

In the long term, this initiative has the potential to completely transform Spain’s tourism landscape. The shift toward accessible regional travel is in line with Spain’s broader efforts to promote sustainable tourism and boost local economies. Tourists will now be able to explore the parts of Spain that have previously been too difficult to reach, making the country’s diverse offerings even more enticing to those seeking new adventures.

A New Dawn for Spain’s Tourism

Thanks to this technological breakthrough, tourists will soon have the chance to experience Spain’s rich culture, history, and landscapes like never before. The upgrade of low-density railway lines will not only improve the travel experience but also breathe new life into underexplored parts of Spain. As these quieter regions gain visibility and accessibility, Spain is set to offer even more unforgettable memories for those who venture beyond the usual tourist trails. With Spain’s rail network evolving, the journey is about to become just as memorable as the destination itself.
