Spain: Recoletos Tunnel Project Completed

In just five months Alstom has completed the signalling upgrade works in the Recoletos Tunnel in Madrid. The project included modernising the signalling and protection systems, and installing new fixed communications systems.

While Alstom was delivering its part of the project, it also had to co-ordinate with other contractors on site working on the roads and catenary infrastructure.

As Railway-News reported in October, ADIF has invested 45 million euros in refurbishing the 7km tunnel. These upgrade works should improve the reliability of the line and provide a better service, particularly for Madrid’s suburban network. Furthermore, the works include improved safety measures. These would make evacuation easier, should this become necessary.

Antonio Moreno, Managing Director, Alstom Spain, said:

“The Recoletos Tunnel project has been a real challenge due to the short deadlines and system complexity. The signalling leadership and experience of Alstom teams in Spain have allow {sic} us to successfully achieve our commitment with the client. To reach this goal, a team of more than 140 people from different departments and expertise areas has been coordinated, working 24 hours a day, seven days a week, with alternate shifts.”

The Recoletos Tunnel in Spain is incredibly busy, handling 470 trains and more than 200,000 passengers a day. It is the busiest on the Spanish rail network.

Alstom’s Involvement in the Recoletos Tunnel Upgrade Project

Spanish rail infrastructure manager Adif began works on upgrading the tunnel in June 2018. Alstom won the contract element dealing with the signalling renewal between Atocha Cercanías and Chamartín stations. It included new interlocks for Nuevos Ministerios and Chamartín stations, digital ASFA balises and other infrastructure equipment.

Alstom has also upgraded and relocated the telecommunications wiring, and adapted the signalling at Atocha and Chamartín stations to be in line with the new equipment in the tunnel.
