Railway activities in 2019:
Spain: With 125 years of history, COMSA Corporación is a specialist in turnkey railway projects covering the fields of construction, installations and systems, as well as maintenance of high-speed lines, tramways, and metropolitan and regional railways. In the high-speed sector, it has been involved in the development of all Spanish lines. In 2019, the group started the construction of a section of the Mediterranean Corridor between Murcia and Almería, the construction of sector 3 of the Mondragón, Elorrio and Bergara branch lines of the Basque Y, as well as maintenance of the Madrid-Sur lines. Likewise, its engineering business executed the construction work project for the overhead electric contact line facilities and associated systems of the Plasencia - Peñas Blancas split section for the Madrid-Extremadura high-speed line and the Antequera-Granada section of the Madrid-Granada high speed line.
Regarding its activities on conventional lines, the group has carried out the extension of the burying of the Ferrocarrils de la Generalitat de Catalunya (Catalan rail network) in Sabadell (Barcelona), the maintenance of catenary, substations, traffic control and remote control of energy on the Medina del Campo (Valladolid)-Fuentes de Oñoro (Salamanca) line and the construction of the electric traction substations, auto-transformation centres and overhead high voltage lines in the Cariñena and Villafranca areas of the Zaragoza-Teruel-Sagunto railway line.
In the field of underground systems, COMSA Corporación has taken on the construction of the Lugaritz-Miraconcha section of the San Sebastián Metro underground network (Guipúzcoa) and maintains its presence in those of Barcelona, Madrid, Seville, Málaga and Bilbao with contracts for the conditioning and adaptation of infrastructures, electrical installations and systems.

Furthermore, its concessions area is still operating the Málaga Metro, which in 2019 reached 6.9 million passengers, the Murcia Tram and the Barcelona Tram.
Europe: Backed by its high level of specialisation and its century-old experience, COMSA Corporación has made a firm commitment to markets with high opportunities for the development of new infrastructures and the modernisation of existing ones. To this end, the tramway in the city of Odense (Denmark) is still under construction and the railway line between Gradec and Sveti Ivan Zabno (Croatia), located 40 kilometres from the country's capital, Zagreb, has been completed.
In Poland, among the most emblematic contracts, it highlights the upgrading of line 406 between Szczecin Glowny and Police and the modernisation of track systems, associated infrastructure and stations in the Poznan Glowny and Rokietnica sector of the E59.
Finally, in Portugal, it is carrying out the electrification of the line between Viana do Castelo and Valença Fronteira, and the track and catenary maintenance in the north of the country.

In 2019, the company expanded its contract portfolio in Mexico through the construction of a double-track section for the Veracruz Port and the maintenance of the light train track in Tasquena-Estadio Azteca section. In Brazil, the second phase of line 4 of the São Paulo Metro is underway, as well as a 10-kilometre stretch of track, also in São Paulo, for the company, Rumo Malha Norte.
