A network of three tunnels consisting of a total of 5 tubes and 22 evacuation galleries excavated in a karst massif, a tunnel mouth over 40 metres high shared by three tunnels in a slope traversed by a geological fault and the presence of a protected species under a viaduct are just a few of the technical, geological and environmental challenges faced by the construction teams of the Bergara railway junction. It is a crucial project that will make it possible to split the high-speed line to connect the centre of the Iberian Peninsula to the three provincial capitals of the Basque Country and to France.
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.
Malaysia wants to modernise its railways to make them the main public transport option for its citizens. To do this, a consortium consisting of Ineco, Adif and two Malaysian companies has designed a new open-access model for railway transport in which ownership and management of the infrastructure are unbundled from operation, allowing new private operators to enter.
The installation of energy recovery units in traction substations on the conventional network enables surplus regenerative braking energy to be recovered and returned to the electrical grid, preventing dissipation in the form of heat in the braking resistors of the trains. Since 2010, Ineco has been developing a number of engineering projects for Adif to define and implement these units.
