COMSA Corporación wins electrification works for the Algarve railway line

COMSA Corporación has been awarded the electrification project for the Algarve railway line, in Portugal. The works, to be carried out on a 45 km section, will be executed by the consortium formed by COMSA (construction company), COMSA Industrial (engineering) and FERGRUPO (the group’s subsidiary in Portugal).

The work consists of the electrification of the Tunes-Lagos sector of the Algarve line with a 25kV/50HZ catenary including the traction current return system and protective earth. In order to carry out these works, it is necessary to lower the platform at some points, with additional drainage and embankment works.

The project also includes the construction of the new infrastructure supporting the signalling and telecommunications systems, the remodelling of the drainage system to adapt it to the new troughs and catenary massifs, and the painting of the Vale da Lama bridge.

Finally, it is planned the adaptation of the station and halt buildings to support the new installations, as well as the construction of three overpasses to eliminate level crossings.


COMSA Corporación has been in Portugal for more than 30 years, through its subsidiary FERGRUPO. The group is currently carrying out the renovation project of the Beira Alta line, on the Pampilhosa-Santa Comba Dão section, and the construction of the Mealhada bypass, both of which are part of the Northern International Corridor and considered a priority in Portugal’s Strategic Transport and Infrastructure Plan.

The company also continues to make progress on the railway section between Évora Norte and Freixo on the Southern International Corridor, and on the Mondego Metrobus section between Serpins and Alto de São João.
