Train tracks with protective barriers in a Catalan mountainous landscape

Ferrocarrils de la Generalitat de Catalunya (FGC) has tendered the expansion of its landslide detection system on two slopes of the Lleida-La Pobla de Segur line, involving an investment of 205,869 euros and a 30-week execution period.

This FGC initiative will focus on slope 4, located between the Santa Linya and Àger stops, where a 360-meter static barrier will be installed. On slope 17, between Àger and Cellers-Llimiana, 60 meters of dynamic containment barriers will be placed at the north and south entrances of tunnels 32 and 33, respectively.
The tendered works, valued at 205,869 euros (before VAT), are expected to be completed within 30 weeks once awarded. This action will integrate the preventive warning system for potential rockfalls, known as the Aspa-Fletxa Landslide Detection System, which Ferrocarrils began implementing in 2021.
The Aspa-Fletxa system is a dynamic luminous signaling method that enhances train circulation safety. It indicates the absence of landslides with an illuminated arrow signal, or the detection of disturbances in the nets with an 'X'-shaped signal (aspa), which requires trains to proceed with caution.
This action complements other recent improvements, such as the April award of works for rockfall protection on slope 3 of the same line, at the Santa Linya stop, within the municipality of Les Avellanes i Santa Linya (Noguera). That project included the installation of a 4-meter high and 50-meter long dynamic barrier, along with 1,450 m² of triple-twist mesh on the lower embankment.
Since Ferrocarrils took over the Lleida-La Pobla de Segur line, over 90 million euros have been invested in various maintenance and renovation projects. These include interventions on embankments, tunnels, slopes, bridges, tracks, and facilities, as well as the elimination of level crossings, all aimed at ensuring the infrastructure's robustness and service reliability.
FGC's management of the line has led to continuous growth in demand. Over the past 12 months, the number of journeys exceeded half a million for the first time, reaching 501,732. In the first four months of this year, 161,887 journeys have already been recorded, representing an 11.81% increase compared to the same period last year.
