Algeria is one of Alstom Transport’s main global markets and Spain has become the Group’s export platform for tram projects in this country. Numerous urban projects in this country are currently managed and implemented by Alstom Transport in Spain. Alstom’s industrial and engineering centres in Madrid and Barcelona have developed tram systems (including supplying rolling stock, power supply systems and signalling systems) for the Algerian cities of Annaba, Algiers, Constantine, Ouargla, Mostaganen, Oran, Sétif, and Sidi Bel Abbès
The Alstom Spain centres responsible for implementing these projects are:
• The industrial plant in Santa Perpetua (Barcelona) for tram manufacturing.
• The technology laboratories and engineering centre in Madrid, for the development of signalling systems, control centres, safety installations and passenger information systems.
• The infrastructure teams for the supply and installation of substations and power supply systems.
The company, part of Essentium Group, is performing the construction works for the first tramway line of Ouargla city, that involve the infrastructure and superstructure works, in addition to the catenary, street lighting, signing and traffic-light installations.This infrastructure project represents 200 M€ of investment and has started on September 2013. The works are scheduled to be completed during the year to come according to the forecast execution deadline. The rail line will connect Ouargla city centre to its university area. The new transport service expected capacity is of 5,000 passengers / hour and includes 34 double trips a day with a 12-minute frequency. The execution of this rail stretch requires the construction of a Cable-stayed bridge, with a bowstring type design, above the RN49, one of the main city roads. The bridge will be made of a structure composed of reinforced concrete and structural steel. The construction of two walkways will be carried out at the same time. Assignia will use 7,000 cubic metres of reinforced concrete, 630 tons of corrugated steel and 145 tons of high strength structural steel.
ArcelorMittal has contributed to the construction of the first tram line in Oran together with Isolux Corsan by supplying more than 4,500 tonnes grooved rail (tram). ArcelorMittal as a leading manufacturer of rail, including metro and tram, will continue playing an active role in the modernization of urban transport in Algeria as it has already done in neighboring countries such as Tunisia and Morocco..
CAF is one of the suppliers of urban railway transport solutions in Algeria. In 2006, the company signed a contract with EMA (Entreprise Metro d’Alger) in consortium with Siemens and Vinci Constructions for the design and manufacture of the first metro line in the city of Algiers to connect Haï el Badr with Tafourah Grande Poste.
The project includes the system infrastructure, signaling and electrification, as well as the supply of trains and workshop equipment. CAF has provided 14 metro units, as well as the workshop equipment and the supply of auxiliary vehicles. The company is also in charge of maintenance of this new fleet.
CETEST testing laboratory carried out, in 2011, tests for the evaluation of vibration levels and passenger comfort on the new units of Alger Metro. Interior and exterior noise emitted by the units was also evaluated.
Euroestudios, company member of TPF group associated to Getinsa-Payma, is part of the JV that will supervise the construction of the extension of Algiers metro between El Harrach suburb and the airport. The project
involves the construction of 9.560 km of underground metro line implemented by TBM system, 10 ventilation shafts and 9 stations. This 60-months supervision contract amounts to around 17.7 mill EUR.
In recent years, Idom is designing in Algeria an important number of urban transport projects ( metro, Tramway and railway). Idom has had an office in Algeria, providing support to the these and other many projects being undertaken in architectural, energy and consultancy fields.
One of most important urban transport projects IDOM is developing for the public company Métro d’Alger, is undertaking an ambitious Extension Plan, increasing the current line 1 (8.2 km) in operation to a network of 55 km with more than 55 stations.The project developed by Idom is for the Ain Naadja-Baraki section. With a length of 6.2 km and 6 new stations, this section will serve two densely populated districts giving them access to the city centre. This integral project has considered all the technologies that will be required for the definition of future works, from civil engineering, urban integration, demand, studies on operations, and all the necessary for the section electrification, signalling, telecommunications equipment and commercial management.
In addition IDOM is designing and supervising Tramway extension in Constantine Ali Mendjeli to the airport with 13,1 km length and 15 stations. Also EL Khorub tramway Constantine extension project with 13,5 km and 11 stations is designed by IDOM.
In Ouargla Tramway IDOM is detailed designer for the constructor Consortium ( Elecnor, Rover Alcisa and Assignia) in a Design and Build project od 5 km length and 11 stations.
◗ SIEMENS RAIL AUTOMATION
Siemens Rail Automation was awarded in 2006 with the contract for the supply of the signalling sub-system for the Line 1 of Algiers Metro which includes an underground line of 8.5 km, 10 stations and 1 Depot.
The contract includes the supply of 4 Electronic Interlocking Westrace, Jointless Track Circuits FS 3000 5K, Electrical Point Machines MD 2000 as well as the optical signals and the corresponding signalling cables. The equipment of Siemens Rail Automation is part of the Automatic Train Control System (ATC) of CBTC technology to be supplied by Siemens France and is based on the same equipment and interfaces for Barcelona Metro Line 9.
◗ ROVER ALCISA
The company is carrying out works in the tram of Ouargla.The lot nº 1 was awarded to the joint venture formed by Rover Alcisa-Elecnor-Assignia by an amount of about EUR 230 million and the lot nº 2 was awarded to Alstom.
The lot nº 1 comprises the accomplishment of infrastructures and buildings, as well as the track line, the catenary, urbanization and non-railway facilities of the maintenance buildings. Within works is included the accomplishment of a bow-string bridge to save a highway. The works of this lot will be executed in two phases, the first of which is composed of the maintenance centre and 8 km of double track, being the rest the objective of the second phase.
The works began in September of 2013, being the accomplishment of a camp and the services deviation the first works made. At this moment, the work has an approximate advance of 35% and the conclusion of phase 1 is anticipated for June of 2.016.
The works are developed in a particularly difficult environment with extreme temperatures in summer that arrive at 50 degrees. It has had to deploy a team of about 40 technicians for the execution of the works, who are supported by the equipment in Spain for the development of the project and to coordinate the logistics of the provisions. The project must adapt to the conditions of the climate and the sand of the desert that affects the elements of itself, reason why the facilities and equipment must design with these inputs.
The experience acquired in railway works in Spain, especially by Rover Alcisa and Assignia, both members of Mafex, will contribute to the success of the project.
