Since July 2021, Sol multimodal station has been connected to the recently renovated Gran Vía metro station via a pedestrian tunnel. Ineco drew up the commissioning plan and supervised the works for this underground connection, which serves 22,000 users every day in the heart of the Spanish capital.

After 52 years in service, the Recoletos tunnel in Madrid, the backbone of the Madrid railway system and the busiest tunnel in Spain, is undergoing a complete renovation designed and managed by Ineco. Its 7.3 kilometres connect the two major stations of Atocha and Chamartín along the city’s most important urban axis.
