Engineers in Madrid have almost finished a 1.1 million euro project to renew a section of the city’s oldest metro line.
Madrid Metro is hoping to restore services to the line by mid-September, having closed it to trains on June 29.
Between Bilbao and Vodafone Sol Stations, workers exposed the tunnel’s steel framework before shotcreting and injecting fresh grout into the ground to reduce settlement.
The Regional Secretary of Transport, Infrastructure and Housing, Pablo Cavero, visited the section of tunnel last week to see how the repair programme was progressing.
The 23km Line 1 was officially opened by King Alfonso XIII on October 17, 1919, making it the oldest line on the network.
