Adif will invest 14 million euros to modernize the catenary of the metric-gage network in Cantabria. This new action is part of the Plan de Cercanías, which will increase the reliability of the electrification systems, improve the response to potential incidents and facilitate maintenance tasks.

All the disconnect switches in the network’s catenary will be replaced, and they will also be integrated into a remote control system so that the devices can be monitored and controlled automatically. 

The work – which includes all the installation operations, integration of the equipment, supply, installation, configuration and commissioning – will be supervised by Inse Rail. 

Catenary disconnect switches are the devices that make it possible to mechanically separate an electrical circuit from its power supply, isolating it in a section or segment of the line. This makes it safe to work on the electrical network and makes it possible to isolate sections of the catenary in case of malfunctions so that trains can continue to travel over the rest of the network.

This action joins other initiatives related to the network’s electrification that are currently underway, such as the new substations in Santander, Virgen de la Peña (both in the project-design phase) and Requejada (under construction).

Adif has awarded Inse Rail the contract to provide technical assistance in the supervision of the works to remodel and modernize the Grisén railway station on the Madrid-Zaragoza conventional-gage line, located in the Ribera Alta del Ebro region (Zaragoza).

The construction project for the remodel was designed by Inse Rail to expand the functionality and operation of the station’s layout to improve traffic performance and improve operating efficiency.

The comprehensive remodeling of the station, which has several siding tracks and an industrial siding for the Opel automobile factory, includes the overhaul of the track yard configuration and layout to increase the travel speed of passenger trains between Madrid and Navarra/Basque Country/La Rioja, and the reorganization of the tracks in the siding to extend the useful length of two of them (3A and 3B) to 750 m.  The platform will also be expanded to respond to the needs of the new track configuration and the structure over the Canal Imperial de Aragón will be prepared.

The work includes the installation of new elements (rails, sleepers and ballast) and trackside devices, the comprehensive modernization of the electrification system, and the relocation of the lighting installations. The platforms will also be raised, a new central platform will be created, the main platform next to the passenger building will be reconstructed, and a new underpass equipped with stairs and ramps will be built under the platforms.

Adif Alta Velocidad has awarded the engineering consortium made up of Inse Rail, Grusamar, Eptisa and GOC the contract to supervise the works of the future Atocha transit station that will allow trains that leave from Chamartín Station to stop at Madrid’s southern terminal, and will also expand the terminal’s capacity.

The supervision contract has a budget of 17.7 million euros and a completion time of 7.5 years.

This is the final action in the railway manager’s ambitious plan to expand the capacity of the high-speed network, and will turn Madrid “into one large train station with two terminals, Atocha and Chamartín”. It will connect the high-speed tunnel that passes through Madrid from north to south with the route used by trains from Barcelona and Andalusia, enabling them to continue to destinations in the north of the Peninsula.

The transit station will be located underground beneath the existing Puerta de Atocha station and Calle Méndez Álvaro. It will have four new tracks and two platforms, and although the execution involves a “high degree of technical complexity”, train traffic will not have to be cut off. It will have two entrances: one, to the north, from the existing terminal and another to the south, to give access to the Méndez Álvaro area, where an intermode platform for taxis, VTCs and private vehicles will be installed. The northern part of Puerta de Atocha will also be remodeled.

The project will be carried out on several levels: the platforms will be located at an elevation of 600 meters; above that, at 607 meters, there will be two boarding halls to the north and south, as well as the connecting walkways. The southern lobby of Méndez Álvaro will be located on an upper floor, at 611 meters and will include the taxi stand; and at 624 meters it will connect with the first floor of the Puerta de Atocha departure lobby. The underground station will also include a central skylight and a curtain wall.

Inse Rail has been awarded the contract to supervise the works to renovate the 43 km of track in the Bobadilla-Ronda. This investment is an important step forward in the renovation and modernization of the conventional railway line between Bobadilla-Algeciras (176 km), between the provinces of Málaga and Cádiz.

The action, which is being executed through Adif, will replace all of the track elements (ballast, sleepers and rail) in the section with new and improved elements.

The dimensions of the overpasses will also be adapted to accommodate the poles and equipment for the future electrification of the line, and infrastructure, different points on the route and the drainage system will be reinforced.

This action moves forward with the comprehensive renovation plan of the Bobadilla-Algeciras line, which also includes the installation and electrification of a third rail, and the expansion of sidings.

Inse Rail, in a joint venture with the companies GPO and Airtren, has been awarded the ADIF contract to supervise the works on the installations of the ERTMS train protection systems and fixed telecommunications, GSM-R mobile telecommunications, ground train and control and signaling control safety installations in the provisional phase, in the Montcada Bifurcación, Montcada Bifurcación Aigües  and Montcada i Reixac stations (including adjacent stations and their routes) to adapt them to the new track configuration, in accordance with the remodeling and tunneling works that will be carried out with the execution of the infrastructure and catenary construction projects.

The actions are divided into three main projects:

• Construction project Safety Installations impact of the remodeling of Montcada Bifurcación.
• Construction project for the execution of the Control, Command and Signaling provisional phases in Bifurcación Aigües.
• Construction project for the execution of the Control, Command and Signaling provisional phases of the Montcada i Reixac tuneling.
