Mafex members with ERTMS projects

In Spain, following the success of the installation of ERTMS level 2 in the Albacete-Alicante line (first exclusive system level 2, without Level 1), Alstom has led the adjudication of new ERTMS systems for the Spanish rail network.
At European level, 3 out of 4 trains using the system ERTMS do it with the Atlas solution developed by Alstom.

With more than 10 years of experience in the installation of ERTMS solutions, Alstom is one of the worldwide pioneers in the development and implementation of this technology, with projects in 23 countries giving service to 1,200 km of rail and more than 5,200 on-board equipments.

In Spain, after the success of the installation of ERTMS level 2 in Albacete-Alicante line (the first exclusive level 2 system, without level 1), Alstom has led the adjudications of new ERTMS systems for the Spanish railway network. Thereby, Alstom has installed or is installing ERTMS technology in the Atlantic corridor (A Coruña-Santiago and Santiago-Vigo), in the Levante corridor (Albacete-Alicante), in the Mediterranean corridor (connection with French border), in the Zaragoza-Huesca connection, in the Norwest corridor (Valladolid-Leon-Burgos), in the Extremadura corridor (Plasencia-Caceres-Badajoz) and in the Barcelona commuter network (L’Hospitalet de Llobregat and Mataro).

Alstom Spain was also the first manufacturer to incorporate ERTMS to a commuter network, installing on-board equipments in 112 trains Civia in Madrid.

The signalling and safety division of Alstom Spain has more than 400 technicians and engineers dedicated to develop and implement signalling solutions for all kind of railway infrastructures. Moreover, we are the worldwide Competence Center of light rail signalling and safety solutions.

First line in Europe
Ten years ago, in December 2005, Alstom has driven innovation in the field of signalling and railway safety by being the first to put into service its ERTMS Level 2 radio-based system, the latest in the market. Alstom ERTMS level 2 (Atlas 200) started to operate on the Rome-Napoles high-speed line in Italy, the first route to have a signalling system based in GSMR, and freeing the train control system from the constraints and cost of trackside signal lights.

Since the first line implemented in Italy, Alstom has maintained its position as a market leader for interoperable ERTMS level 2 systems in operation. The Atlas solution equipped the first high density line in Switzerland (2006), the first freight line in The Netherlands (2007) and the first cross border operation (2009). Also, Alstom has supplied the on-board equipments operating under ERTMS level 2 in Germany. It is also participating in the putting into service of ERTMS level 2 lines in UAE and in Saudi Arabia.

Indra has developed revolutionary solutions for level 2 interoperable ERTMS signaling. These include a proprietary RBC system, the required wayside component and cornerstone of the system, which has been granted interoperability certification and top-level SIL4 security certification, as well as the onboard equipment (Eurocabina), also SIL 4 certified. The solution is part of InVITALRAIL, an innovative technology platform for highly scalable and adaptable top-level safety systems. It is a fully generic system that guarantees interoperability with any system from any supplier. It complies with the most stringent quality and security standards (SIL4). Having already undergone testing and certification, the platform is being deployed on a number of projects in Spain and internationally.

Thus, continuing its development of open and integration-ready ERTMS, Indra has developed the first open security protocol between the interlocking and RBC systems, based on the RaSTA (Rail Safe Transport Application) standard. This solution will help drive the globalization of the interoperability concept, extending the scope of standardized integration between signaling systems and train control systems, acting as a technological driver based on infrastructure scalability and optimization.

In 1989, Siemens, as leader of the Hispanic-German consortium, was entrusted to lay the foundation stone in High Speed Lines construction in Spain after the awarding of Madrid-Seville High Speed Line, opened in 1992, coinciding with the Universal Exhibition in Seville. Since that date, this company has become a reference within the railway sector in Spain and worldwide, and nowadays it can be said that Siemens has participated almost in all the High Speed Lines currently operating or under construction in Spain: Madrid-Seville, Madrid-Toledo, Madrid–Segovia-Valladolid, Valladolid-Leon, Madrid-Barcelona, Lleida-Barcelona, Barcelona-French border, Madrid-Valencia, Córdoba-Málaga, Antequera-Granada and Olmedo–Orense–Santiago.

Another historical fact took place in 2007 with the commissioning of the first one of the 26 AVE S103 units, the first one in getting the authorization for the commercial operation service under ERTMS Level 2 in Spain. Siemens was also responsible for equipping, for Renfe, Siemens AVE S103 fleet as well as both Talgo-Bombardier AVE S102 and S112 fleets with the on-board equipment Trainguard 200, specific for Level 2. Regarding international projects, it is worth mentioning the Meca-Medina High Speed Line (within the Haramain project), Ankara-Konya High Speed Line (in Turkey) and the Marmaray project (also in Turkey).

The level 2 ERTMS of Bombardier, present in various sections of Spain, as well as in Europe and Asia.

Since Bombardier’s implementation of the world’s first ERTMS Level 2 line in full commercial operation in April 2002 with outstanding performance levels of 99.6% on-time performance, we have rapidly become a world leader in this field. Bombardier built an invaluable foundation of know-how and trained specialists to continue implementing ERTMS technology on rail routes worldwide.

The INTERFLO 250 solution receives information from the EBI Link lineside electronic unit (LEU), which transmits it to the train via balises, and can easily be upgraded to INTERFLO 450 ERTMS Level 2. This enables the onboard equipment to use radio-based signalling on ERTMS Level 2 and regional ERTMS lines.

The INTERFLO 450 ERTMS Level 2 solution is characterised by the wayside system providing continuously updated information to the train to ensure safe operation.

INTERFLO 450 supports very high levels of operational safety and removes the need for the installation and maintenance of wayside equipment, particularly light signals and their support systems and similarly reduces civil works and cabling supply and works. Having signals displayed in the cab presents the opportunity for higher line speeds and increased capacity.

The INTERFLO 550 solution is a digital radio-based signalling system for low density regional lines which significantly reduces the cost of rail operations (OPEX). Cost-intensive manual operations can therefore be replaced by the INTERFLO 550 solution, improving economy, capacity and safety. INTERFLO 550 utilises the Class 1 ERTMS/ETCS specifications providing full interoperability for ERTMS fitted trains.

In Spain, Bombardier, in partnership with other companies, has supplied the ERTMS Level 2 for various railway sections such as the Palencia-Burgos (correspondent to the railway corridor Valladolid-León-Burgos), the corridor of Plasencia-Cáceres-Badajoz and the section between Hospitalet de Llobregat-Mataró, of Rodalies. The ERTMS Level 2 has also on board in the AVE 130.

On an international level, it’s presence in China stands out. In Europe, it is present in the section between Amsterdam and Utrecht, besides being implemented in Polonia and at a pilot line in Sweden.


One of the first ERTMS implementation projects of IDOM was for the Spanish Railway Infrastructure Administrator (ADIF). The firm carried out the role of project manager of the contract which included Design, Build and Maintenance of the Signalling system, Train Protection systems, Telecommunications systems, GSM-R Radio system and related systems for the last section of the Barcelona-French border High Speed Line. The Scope of Works included ERTMS Level 1 and 2 for a section of 186 km. The Lleida-Barcelona section included the following railway facilities: crossing posts (Les Borges Blanques, Camp de Tarragona Station, La Pobla de Montornés, Gelida), passing loops (L’Espluga de Francolí, L’Arboç, Vilafranca del Penedés, Sant Viçents dels Horts, El Prat de Llobregat station, Barcelona Sants station).

The Signalling works commenced in April, 2004. By December, 2006, the 91 km length section (Lleida-Roda de Barà) started commercial operation, extending the Madrid-Zaragoza-Lleida high-speed line. An ERTMS Level 1 system adopting SRS UNISIG specifications were tested and commissioned, allowing a maximum speed of 300 km/h for the Lleida-Tarragona section.

Since these beginnings, Idom has continued to design and implement ETCS solutions.
At present, IDOM is working in Croatia preparing studies, designs and obtaining the necessary permits for the implementation of the Upgrade and Construction of a 43 km Second Track (Križevci–Koprivnica–state border section). This project is being developed for HŽ Infrastruktura with funding from the EU. The engineers of Idom have been designing an ERTMS Level 1 system with speeds of up to 160 km/h (Lepavina – state border). This system is based on the national PZB system with ETCS 3.0.0 UNISIG centralized for the stations of Lepavina, Koprivnica and the future station of Novo Drnje. The design includes entry/exiting areas for the ETCS Territory (Osijek-Varaždin connection). The signalling design includes road level crossings which will not be interrupted by the civil works. The design has contemplated that the ETCS balises will be compliant with ERTMS Level 2, allowing for speeds of up to 200 km/h.

Idom is also working on a high-speed project in Sweden, East Link Branch. Once the preliminary design of the track alignment has been concluded, Idom will begin designing the ERTMS system for the new line.

Ineco supervises the deployment of ERTMS in European corridors.

Ineco’s experience and knowledge in ERTMS have led the ERA to rely on the Spanish engineering company for the sixth consecutive year for technical assistance and supervision of ERTMS/ETCS interoperability in more than 40 European projects.

The projects include, for example, implementing ERTMS in the Swedish, Belgian and Austrian network, or equipping vehicles with ERTMS in Germany, Czech Republic and The Netherlands.
