Ineco has drafted the preliminary studies and projects and managed the works for the comprehensive renovation of this 217-kilometre historic line that crosses the Cantabrian Mountains. Built 150 years ago, it is still a vital corridor both for freight –especially vehicles manufactured in Castilla y León– and for rail passengers. The duplication of sections of track between Santander and Torrelavega, which is expected to start in 2019, will complete improvements in speed, safety, passenger comfort and freight capacity.
