ADIF awards Inse Rail the contract for the supervision of the works to renovate the infrastructure and track between the Redondela and Vigo stations

Inse Rail, in a joint venture with the company Ofiteco, has been awarded the contract to supervise the works of the construction project for the comprehensive overhaul of infrastructure and track in the section connecting the Redondela and Vigo-Guixar stations, in the province of Pontevedra, on the Monforte de Lemos – Chapela Split line.

This action is aimed at upgrading and optimizing one of the region’s most important railway lines, which will improve the capacity, efficiency and reliability of the route to the benefit of both passengers and freight transport.

The action includes renovation of the track on the route by installing sleepers, ballast and new and improved turnouts, and adapting it for the future upgrading of the line’s electrification.

In the Chapela neighborhood, a new stop with a 220 m platform will be built close to a parking lot, with a pedestrian walkway over the tracks. This will improve the mobility conditions for citizens and better integrate the railway into the surrounding area.

A new central platform longer than the existing platform will be built in the Redondela station, and the rest of the platforms will be expanded. All of the platforms will be connected with a new underpass. 

At the Vigo-Guixar station, Adif will install new and improved turnouts and will extend the platform at the head of the tracks to allow arrivals and departures of trains longer than 600 m. 

The project also includes actions in the Vigo tunnel – from the reinforcement of the waterproofing, tunnel lining and drainage, to the adaptation of the tunnel gauge for new electrification in the future – and with improvements to embankments, cuts, drainage and other elements of the line.

This action is another advance in Adif’s plan, with an investment of 265 million euros, to upgrade the entire Ourense-Vigo Guixar line, or ‘Miño Line’, which includes the Guillarei-Portuguese border connection. This will adapt the line to the parameters of the Atlantic Corridor, strengthen the connection with Portugal, and increase the capacity for both passenger and freight traffic.

Inse Rail to supervise the works to adapt the Madrid-Zaragoza stretch to the Rolling Highway

Inse Rail, as part of a joint venture, has been awarded the contract to supervise the works to adapt the Madrid-Zaragoza stretch to the Rolling Highway (RH) of the Algeciras-Zaragoza route.

The RH is a cargo transport service that loads highway trailers or semi-trailers, using specialized cars. The initiative offers a competitive and collaborative logistics solution that significantly reduces both external costs and GHG emissions. Highway transport emits 4.7 times more GHGs than rail (annual savings: 620,000 tn CO2).

The work consists of adapting the railway loading gauge of tunnels and overpasses to the dimensions required for the semi-trailers that will use the RH service between Madrid and Zaragoza.  This will require the modification of 40 overpasses and 26 tunnels on the conventional-gage line between the provinces of Madrid, Guadalajara, Soria and Zaragoza.

This will involve modification of the infrastructure, such as the expansion of the tunnel cross-sections and lowering of the platform, as well as changes to the superstructure, including renovation of sleepers, rails and ballast, as well as drainage and electrification work. 

The framework of the actions between Madrid and Zaragoza to develop the Rolling Highway also includes extending the siding tracks of the Épila, Morés, Paracuellos-Sabiñán, Arcos de Jalón, Sigüenza, Jadraque, and Humanes de Mohernando stations to a length of 750 m.

This will make it possible to park trains and allow trains of interoperable lengths to cross, increasing the capacity, efficiency and competitivity of the line to promote railway transport of freight.

The implementation of the Algeciras-Zaragoza RH service will be crucial to increase the share of railway transport on the central branch of the Mediterranean Corridor as well as on the Atlantic Corridor. It will also strengthen intermodality on the Iberian Peninsula with traffic between Europe and Morocco.

The Algeciras-Zaragoza route will carry 6 trains per day (three in each direction) with trucks to/from Morocco, in addition to 2 trains per day (one each way) from Huelva to Zaragoza, with trucks to/from the Canary Islands and the area around Huelva; and another 4 trains per day (two each way) Sevilla-Zaragoza, with truck to/from the Port of Sevilla and Andalusia.

This means that each day, approximately 12,000 train-km will be covered, and approximately 360 trucks will be carried on this route, avoiding 360,000 km of highway truck traffic per day.   

The services of the Algeciras-Zaragoza RH will continue from Zaragoza to Tarragona, through Lleida. This stretch connects the Main production and consumption nodes of the Iberian Peninsula, Madrid and Barcelona, and forms part of the flow between the center and south, and northeast Spain and the rest of Europe. 

These actions will help achieve Sustainable Development Goal (SDG) 8, which is aimed at promoting sustained, inclusive and sustainable economic growth; and SDG 9, whose aims include the development of reliable, sustainable, resilient and high quality infrastructure.

Inse Rail awarded the contract to supervise the modernization works of the catenary of the metric-gage network in Cantabria

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).

Inse Rail, awarded the contract to supervise the works of the Atocha transit station, in consortium with three other engineering firms

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 to supervise the works for the reorganization of the new track arrangement in Atocha station

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.
