ADIF awards Inse Rail the supervision of the works to renovate the safety installations of the Peñalajo-Espeluy section, line 400

The contract, which was awarded to Inse Rail in a joint venture with two other companies, covers a stretch of 94 kilometers that falls entirely within the provinces of Ciudad Real and Jaén. It is part of Line 400 (Alcázar de San Juan – Cádiz) of the General Interest Railway Network (RFIG). This section includes several stations and stops that handle medium and long distance trains of Renfe Operadora, as well as freight traffic.

Over the next few years, a variety of actions that are currently in the project or planning phase will be carried out, including the extension of sidings with to 750 meters at different points. Much of the route will be also be integrated into the future Algeciras-Zaragoza rolling highway, which increase traffic significantly and will require infrastructure with greater capacity and improved reliability.

The section currently has 36 interlockings that use various technologies. Many of these – especially those with free cabling and geographical groups – use obsolete technology that is incompatible with future track modifications that will be required for the planned expansion projects.

The renovation includes the installation of new state-of-the-art signaling equipment, along with the implementation of centralized control and command systems. All of the field equipment will be replaced, incorporating signals with LED lights, axle counters in stations, audio-frequency track circuits on the routes and an ASFA Digital protection system. All the existing switches in the stations will be replaced with electromechanical drives, including the turnouts that give access to the main tracks that are currently non-motorized.

The cab equipment will also be updated with the installation of state-of-the-art electronic interlocks (ENCE) in all stations. These systems will be located in new technical buildings, designed to house the signaling and communications rooms, which will allow a safer, more efficient operation prepared for the future growth of rail traffic.

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

The project awarded by ADIF to Inse Rail, as part of a joint venture, will eliminate 12 grade crossings, increase the permeability of the infrastructure and minimize the possibility of flooding in the municipality, according to the informational study approved by the Ministry of Transport and Sustainable Mobility.

After a preliminary analysis of construction solutions, the project will develop a railway bypass that will connect the Bilbao-Balmaseda and Santander-Bilbao lines, freeing up more than a kilometer of track through the city center and eliminating grade crossings. In addition, the existing stop in Aranguren will be replaced with a new one.

The project will also include actions on two railway bridges that cross the Cadagua River, near the Aranguren stop. One of these will be dismantled, and the span (space between piers) will be extended to increase its water capacity, integrating the improvements to the waterway planned by the Basque Water Agency (URA).

These operations will be carried out in coordination with the URA, which also carries out flood protection actions in the area, specifically from the shallows located near the Aranguren station track yard to the commercial area of the Baular neighborhood. 

The drafting of this project, as well as the later execution of the works by Adif, is part of the protocol signed by the Ministry of Transport, Adif, the Basque Water Agency and the Zalla City Council.

Inse Rail to supervise the works to extend siding tracks to 750 meters in three stations in Córdoba

ADIF has awarded INSE RAIL, in a joint venture, the contract for the supervision of the works of the projects to increase the length of the siding tracks in the Fernán Núñez, Montilla and Puente Genil stations to 750 m. These stations are part of the conventional gauge L/430 Córdoba Mercancías – Los Prados line, which connects the provinces of Córdoba and Malaga.

INSE RAIL also drafted the project for the three stations.

These actions are aimed at achieving the conformity of the stations and to allow the parking and crossing of trains up to 750 meters long. The extension of these siding tracks will improve the capacity, efficiency and competitiveness of the line, helping reduce external and internal costs of freight transport.

The works consist of the extension of the platform, the refurbishment of the old platform in the platform area and the installation of the track on the extended route. The extended tracks will also be electrified and the catenary in the stations will be adapted to equip them with rigid frames. The drainage system will also be adapted to the new track configuration.

In addition, the existing overpass in the Montilla station will be replaced with a longer one.

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).
