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.

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).

This Wednesday, after an investment of 267 million euros, the Cadiz Bay tram started running to link the towns of Cadiz, San Fernando and Chiclana.

The route is 24 kilometers long and includes 21 stops. It will service a population of 234,000 inhabitants located less than a thousand meters away from a stop.

The tram-bahía is a bimodal public transport system that combines the best of trains and trams. It is the first time that a vehicle designed to travel in urban areas has carried passengers on the national railway network.

The vehicles are designed to withstand encounters with high-performance trains, allowing them to travel on the railway, reaching speeds of up to 100 kilometers per hour and reducing the travel time from one municipality to another. They have a system of doors, windows and ventilation designed to be able to go from a minimum speed on the route through the historic center to crossing paths with trains at 160 km/hour.

They also have a dual power supply system to adapt to both sections, and the interior is divided into different heights separated by ramps or steps, which is the only way for passengers to get on and off at both the train stops and in the city.

It is also the only train in Spain with elastic wheels, unlike the metal wheels that Renfe uses.

The project design began two decades ago and the works started 16 years ago. The technical complexity multiplied the planned investment and delayed implementation multiple times.

Inse Rail, in a joint venture with TPF Getinsa and Aertec, has been involved in this important project since 2010, as the construction manager of energy installations, signaling and communications systems, and workshop and depot equipment.

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.
