Construction Engineering

Adif has begun the works on the Safety, Communications, Energy and Civil Works Installations and the implementation of the GSM-R Mobile Communications system on the Humanes-Monfragüe section, which is part of the Madrid – Valencia de Alcántara conventional gage line, as it passes through the Region of Madrid and the provinces of Toledo and Cáceres.

The works will increase the reliability of the infrastructure and the quality of service on 230 km of the line, which will be able to be connected to the Madrid – Extremadura High Speed Line. The tasks represent a qualitative leap in the operation of the line, with the implementation of new railway regulation and control systems, by eliminating the existing telephone blocks.

The action, which requires an investment of 54 million euros, includes the drafting of the projects, the execution of the works and maintenance of the installations. To this amount we must add the technical assistance work to monitor and control the works, which will be done by Inse Rail.

The works and activities that will be carried out as part of the technical assistance contract are the analysis, review and control of the construction projects, modified projects and liquidation projects, monitoring and control of the work prior to the execution of the works, monitoring and control during construction and installation of the works, and monitoring and control of work after the construction.

The scope of the contract includes actions on the safety installations, train protection systems, fixed-line telecommunications, mobile telecommunications, Centralized Traffic Control (CTC), auxiliary detection systems, energy supply, civil works for technical and auxiliary buildings, as well as testing and commissioning.

Other elements that are planned include the installation of new electronic interlockings (devices used to automatically establish railway routes, which can be activated remotely), as well as different auxiliary equipment in stations and along the length of the track; fiber-optic transmission networks and base stations for fixed and mobile telecommunications; transformer substations and cables for the supply of electrical power to the installations.

Likewise, there are plans to integrate the line into the CTC to automate the regulation and supervision of traffic, as well as the execution of the civil works required to integrate the new equipment into the infrastructure, locate technical shelters, etc.
