Inse Rail, in a joint venture with the company Grusamar, will supervise the works promoted by Adif to reorganize the tracks of the Atocha Cercanías station with the implementation of a new arrangement (4+4+2) that will improve the management of the railway traffic of the station. 

The action is part of the Madrid Cercanías Plan and will increase the capacity of the C-3 and C-4 lines that run through the Sol tunnel. It will also expand platform 5 that serves passengers on line C-5.

New 4+4+2 track arrangement
The changing of the tracks to a 4+4+2 arrangement in the northern header station will assign tracks 1 to 4 to the Recoletos tunnel, tracks 5 to 8 to the Sol tunnel and tracks 9 and 10 to the Embajadores tunnel. It will also allow track 8 to be used as a siding track for line C-5 in the event of an incident. 

Likewise, platform 5, which serves tracks 9 and 10, will be extended and widened to increase its capacity and use it for passengers to get on and off line C-5 in both traffic directions. 

The Atocha Cercanías station currently has ten tracks with platforms in a 4+3+3 configuration, so this remodeling represents a significant change that will improve the movement of the most heavily used lines. 

The Cercanías commuter trains are the ones that travel through Atocha the most, but the movement of Medium and Long Distance trains may also be affected in the future.

The contract awarded to Inse Rail, as part of a joint venture with Ayesa, covers the outfitting, modification and overhaul of the safety and communications installations to migrate the L050 high-speed line that is currently in service to the new route that runs through the future Sagrera station on its second railway level. The contract also includes the commissioning and integration into the systems managed from Madrid, Zaragoza and Barcelona (CRC, PRO, CTC, BSC, …) and its impact on the Barcelona-Sants and Bifurcación Mollet stations, and connections with other lines.

The upgrading of existing facilities and the installation of new is part of a large-scale change reported to the AESF. It includes contracts for the infrastructure, energy, control, command and signaling subsystems, ERTMS train protection systems and fixed telecommunications, with the different works executed interdependently and in parallel.

The La Sagrera station is the largest infrastructure currently under construction in Catalonia and one of the most ambitious and complex projects in recent years in Spain. The project is being carried out in Barcelona’s large multimodal transport hub, which will host high-speed and long-distance, medium-distance and commuter services -Rodalies-, metro and urban and intercity buses.

Adif is moving forward with the project to eliminate telephone blocking on the Bobadilla-Ronda section -70.5 km between the provinces of Málaga and Cádiz- of the Bobadilla-Algeciras line, which will be replaced with an advanced signaling and telecommunications system, an Automatic Single-Track Blocking (BAU), which will work with Centralized Traffic Control (CTC). 

The project, with an investment of 27.9 million euros, will improve the reliability of the facilities and the quality of the service. With this project, the system will be implemented along the full length of the railway line, because it is already installed between Ronda and Algeciras (105.5 km).

The works, which involve modifications to the signaling, energy and telecommunications facilities and the installation of new state-of-the-art electronic interlockings, will be supervised by the Inse Rail-Meta Engineering joint venture, with a completion time of 26 months.

The main actions to be carried out are the following:

• Replacement of the electrical interlocking in Bobadilla and the Bouré interlockings in Campillos, Almargen/Cañete La Real and Setenil, with new electronic interlockings.
• Installation of Automatic Single-Track Blocking (BAU) throughout the section.
• Integration of new electronic interlockings in the CTCs in Ronda and Córdoba.
• New technical buildings for signaling and telecommunications facilities in the Bobadilla, Campillos, Almargen/Cañete La Real and Setenil stations, as well as at the intermediate posts in Teba, Atalaya and Parchite.
• In Bobadilla, Campillos and Almargen/Cañete La Real stations, traffic offices will also be built.

ADIF has awarded Inse Rail the supervision of the works to modernize the signaling, energy and communications installations in a 96-kilometer stretch, from the Madrid-Burgos line to the Prado Marina de Aranda de Duero industrial park, with an expected completion period of 18 months.

This action will improve the connection of freight train traffic in this section and, will also incorporate advances in railway operation, increasing the capacity and reliability of the line and improving the regularity of train traffic.

The main actions that will be carried out include:

• Replacement of the electrical interlocking of Aranda de Duero with an electronic one.
• Upgrading the Burgos interlocking.
• Replacement of the signals installed on the track with LED signals with their respective ASFA Digital beacons.
• Installation of new train detection equipment (axle counters) and new turnout motors.
• Establishment of a Single-Track Automatic Release Block throughout the project section.
• Integration of the new interlocking functions in the Miranda de Ebro Centralized Traffic Control (CTC).
• Installation of the Uninterruptible Power Supply (UPS) in the interlocking signaling equipment.
• Laying of fiber optic cable.

The enabling of Single-Track Automatic Blocking in all sections and the installation of electronic interlocks in the entire section will increase the adaptability in the case of future modifications.
