Adif Alta Velocidad, the company that manages Spain's high-speed railway infrastructure, has announced that it will improve the capacity of the Madrid-Galicia High-Speed Line (HSL) by constructing a second track on the 32 km stretch connecting the provinces of Zamora and Ourense, between Pedralba and Vilavella, which is currently a single track.

This additional track will allow a greater number of trains to operate on the high-speed line and will also connect it to the conventional line, allowing for transversal connections. The project is estimated to cost €4.8 million and will not affect high-speed train traffic.

Adif has already begun the tendering process for the drafting of the project, which is the first step before the works can be put out to tender. The development of this action will involve a wide range of works, including the remodelling of the historic Padornelo tunnel, the construction of a new tunnel and two viaducts, track assembly, electrification, installation of turnouts, and renovation of facilities.

The project represents a significant technical challenge due to the volume and variety of works that need to be carried out. Part of this second track will run through the historic Padornelo tunnel, which is 6 km long and will be adapted to high-speed standards. This tunnel runs parallel to the new tunnel of the same name, which channels the current single track of this section of the high-speed line.

The central section of the second track, which includes the newly built platform and the historic Padornelo tunnel, will be shared with the conventional Medina del Campo-Ourense line. Therefore, it will be laid with a three-wire track, which will allow the circulation of both high-speed and conventional trains.

The project will enable the second track of this section of the High-Speed Railway through the installation of track, electrification, safety and communications installations, and other systems on the platform that has already been built along the entire route, except for around one kilometre of its central part. To bridge this distance, the Aciberos Tunnel (445 m) and the Leira (100 m) and Pedro (370 m) viaducts will be built.

This project aligns with Sustainable Development Goal (SDG) 9, which aims to promote sustainable, reliable, and quality infrastructure. It may also be co-financed by the European Union's Connecting Europe Facility (CEF), which is a funding instrument that supports infrastructure projects that contribute to the development of a sustainable and interconnected Europe.
