Metro de Madrid is engaged in strategic projects to overhaul, modernize and legalize the low voltage installations in the oldest stations and facilities of its network to ensure that they conform with regulations. This requires the updating and renovation of the electrical installations, as well as the corresponding legalization procedures.

Inse Rail, along with seven other companies, was selected to carry out these actions, as part of framework agreement signed with Metro de Madrid in February 2019, under which Inse Rail has already executed five support contracts to provide technical assistance to Metro de Madrid in the El Carmen, Puerta de Toledo, Pirámides, Carabanchel and Estación del Arte stations.

These last two contracts make a total of seven Metro de Madrid stations in which Inse Rail will provide its services to overhaul and modernize the energy distribution facilities, which include the subsystems of transformer substations (CTS), general low voltage switchboards (CGBT), low-voltage emergency voltage (ABS), tunnel lighting (ILT), station lighting (ILE), and industrial facility lighting (ILD).

ADIF has awarded Inse Rail the technical assistance contract for the control and supervision of the works to inspect and upgrade the overhead contact line between the Aranguren and Carranza stations and the Carranza substation for the commissioning of the electrification of the section.

The purpose of this contract is to outfit the facilities modern and functional equipment that provides greater reliability and better performance, by replacing the existing equipment in the outdoor installations and the direct-current area, as well as upgrading the protections and control, replacing deteriorated catenary posts and seals.

The project also includes a complete inventory of the condition of the catenary in the Aranguren-Carranza section; tunnel scanning; adaptation of the current catenary with calculations, regulation, running cable and pendulum work; installation of protective visors and fences at tunnel openings and underpasses; inspection of protection at platforms and stations, and elimination of vegetation and pruning along the line to ensure the electrical safety distance from the catenary lines and train clearances.

The upgrade of the overhead contact line in the Aranguren-Carranza section was the final one planned to complete the electrification from Bilbao to Carranza, following completion of the comprehensive reconstruction works of the Callejo and Arroyo tunnels. This project also included the installation of catenary in the tunnels and in the section between them.

The installation works are part of the set of actions included to move the railroad tracks in the municipality of Sant Feliu de Llobregat underground in the section between the stations of Molins de Rei and Cornella.

The purpose of the project is to adapt the sensing systems to the different phases of civil works to move the Sant Feliu de Llobregat station underground in order to maintain service and guarantee the safety of railway traffic.

Some of the main facilities and activities covered by the contract include the interlockings and blocks, signaling facilities and centralized traffic control systems (PLO and CTC), installation of train protection systems, installation of fixed communications and associated systems, energy supply to the facilities, auxiliary civil works, installation of the cable network needed to operate the facilities and environmental integration of the works and facilities.

The integration of the railway into the urban center of Sant Feliu de Llobregat will promote one of the most important urban development and railway transformation projects in the Transformem Rodalies plan, which will eliminate the existing grade crossing, build a new underground station and fully integrate the railway infrastructure in the urban network, creating new spaces for socio-economic activity and promoting new operating arrangements for the railway network in the proximity of Barcelona and its metropolitan area.

Adif is developing a new investment, for more than 22.3 million euros, to advance the modernization of the infrastructure and railway facilities of the Barcelona-Girona-Portbou conventional gage line.

This investment will be used to install a new security and communications system on the Figueres-Portbou section, which is one of the actions in the Rodalies Plan.

Specifically, the system known as the Automatic Two-Way Track Block System (BAB) will be installed on this route. This state-of-the-art equipment allows trains to travel equally in both directions on either trac.

In addition to increasing the capacity conditions of railway operation, it also improves operation and flexibility in train movements, increasing the reliability of the installations and the regularity of traffic. It also increases the commercial speed and decreases the impact in case of incidents.

Inse Rail, in consortium with Airtren, will be in charge of executing the technical assistance services during the execution of the works. 

The estimated completion time is 25 months, with 6 months corresponding to the drafting and approval of the project and the other 19 to the execution of the works.

Some of the most important operations include new installations for computer systems to manage and regulate traffic, as well as for train detection equipment, digital ASFA (Automatic Braking and Signal Announcement), fixed LED signaling lights, and the integration of the facilities into Barcelona’s Centralized Traffic Control (CTC).

It also includes actions in the energy supply system for future installations and additional works on conduits and auxiliary civil works.
