◗ ALSTOM ESPAÑA
Alstom Spain, as leader of the consortium UT Alstom-Sytecsa, has provided the power system of the new Ayacucho Tram, in Medellín, Colombia.
Alstom’s scope includes the project management, engineering, sourcing of traction equipment (medium voltage transformers, DC equipment and control), a centre for distribution and three traction substations with rectification, as well as the testing and control of the substations, which will provide electric power to the trams. These activities will be managed by Alstom Spain with the support of the company´s local team. Alstom’s consortium partner Sytecsa has been be in charge of the installation on the site.The 4.3 km-long line – which has been inaugurated on October the 20th – includes 9 stations and is expected to transport 85,000 passengers per day.
In April 2012, the city of Medellin ordered 12 Translohr STE5 trams (each 39 metres long) from NTL (51% held by Alstom). The NTL trams are highly efficient and offer exceptional benefits in terms of their insertion into the urban landscape, including a clearance gauge of 5.18 metres and a turning radius of 10.5 meters. The trams can easily run on gradients of up to 13%, particularly relevant for the Ayacucho line which includes slopes with gradients of 12%.
The office of IDOM in Medellin, Colombia began its activity in 2010. However, prior to its inauguration, IDOM had already completed many reference projects in the country with the collaboration of numerous Colombian professionals working in the Idom offices in Spain.
IDOM has participated in the most important infrastructure projects undertaken in the last decade, such as the Ayacucho tramway in Medellin (inaugurated in late 2015), Line 1 of the metro of Bogota, the Carrera 80 tramway, and the future Bogotram train-tram line that will link Bogota with the airport.
The 4.4 km Avenida Ayacucho tramway in the city of Medellin, which Idom developed in 2010 was the first tramway in the country, and one of the first in Latin America. From 2011 onwards, Idom has been developing the engineering and architectural detailed design of the Carrera 80 tramway with a length of 17.2 km, and the preliminary design for Line 1 of the Bogota Metro, with an approximate length of 27 km and which is currently under revision. In 2013, Idom opened an office in Bogota, mainly for consultancy projects, with the objective of being closer to the clients located in the central region of the country, such as the National Planning Department, Findeter, and the Chamber of Commerce, among others.
In addition, Idom, with the support of the professionals from the offices of Medellin and Bogota, is working with other important clients in Colombia such as EPM (Empresas Públicas de Medellín) on urban infrastructure and water projects.
It has implemented in Medellin a new intermodal public transport system that has recently been joined by the new tram of Ayacucho, to which the company will provide a full collection system. With Indra’s platform, which enables the combined use of different transport systems and new ticketing, travellers can access the tram of Ayacucho with the same card without contact and enables them to use the metro, BRT buses (bus Rapid Transit), the metro feeder bus routes and three aerial transport lines. Following the renewal of contactless access control systems of the two metro lines of the city, the access control technology of the multinational company will be in all means of transport operated by Metro de Medellin.
Contactless technology allows having implemented the latest technology in terms of performance, scalability, versatility and adaptability, as it is ready to incorporate new payment technologies quickly, easily and transparently. Having a centralized global platform provides also full control over the pricing transactions, allowing customers to explore new models of development and operation of the system.
As a result of previous contracts, Indra implemented in 2008 the DaVinci system for railway traffic management in Medellin and in 2010 began the development of the Metro’s current collection system. In a subsequent project, this system joined the fleet of public buses BRT (Bus Rapid Transit) of Metroplus, which also counts with Indra’s Aid for Exploitation System. The integration of this system with DaVinci has led to an intermodal public transport platform, a pioneer in Colombia, which facilitates the combined use of different means of transport.
This platform has enabled to integrate the operation of trains with the bus system and now with the tram, so that vehicles are treated in a unified way, with special emphasis on networking stations or linking lines. The solution allows managing in a more efficient way the transport service, providing the highest quality and information to travellers, as well as promoting the use of public transport.
Indra is a technological partner of Metro de Medellin and the technology leader for the control of traffic and transport in this city of Colombia. Besides the transportation solution, Indra has also implemented in Medellin intelligent traffic systems (ITS) and a new integrated traffic control system for the city. The new traffic control centre is the largest of Colombia by number of integrated systems under a single platform because it receives, integrates, operates and analyses information from different subsystems of traffic and six independent control centres: Collective Public Transport ; Incidents Centre; Police Fleet Management; Police Logistics and Mobility Planning; Violations Control, and Traffic Light Control Centre.
Medellin is recognized internationally for its commitment to a sustainable mobility with awards as those awarded in 2013 by the Wall Street Journal and Citigroup as the “most innovative city in the world”, the “International Sustainable Transport Award 2012” or the recognition given that same year by the Inter-American Development Bank (IDB) as the “Latin American city model in implementation of Intelligent Transport Systems (ITS)”.
In June 2015, CAF signed a new contract with Medellin Metro for the supply of 20 metro units. These new trains meet the needs of a larger transport capacity in the urban transport system of the city of Medellin. These new metro units are made up of 3 cars each and are able to run on single or double consists. They will reach a maximum operating speed of 80 km/h and offer a capacity of more than 1,100 passengers.
At present, Empresa de Transporte Masivo Valle de Aburrá (Medellin Metro) already operates CAF metros of the same features on its metro lines. Currently the Medellin Metro has two main lines in operation, A and B, extending for a total of 35.5 km in a network of 27 stations. Medellin, located in the natural region called Aburrá Valley, in the Andes Central Mountain Range, is the second largest city in Colombia and has 2.5 million inhabitants. With this new project, the fleet supplied by CAF to this operator will add up to 36 units, underpinning the Company’s firm commitment to the Colombian market. Colombia represents great business opportunities, with projects such as the one of Medellin, or the future Bogotá Metro project among others.
CAF has bolstered its presence in the Latin American market, where it has various projects in countries such as Brazil, Mexico, Venezuela, Chile and Colombia.
SENER carried out the conceptual design, operational design and legal and financial scope of the first subway line in the city of Bogota. SENER, as leader of the winning group, performed the project management and technical development: demand study, study of alternatives and conceptual design of the first subway line.
The work is structured in various stages, covering the economic, urban and transport diagnosis of Bogota; the transport modeling for different venues in the city until 2038; as well as regulatory and financial analysis.
These analysis determined, along with the previous study of alternatives and evaluation, the mass transport network for the SITP, with underground corridors, the Transmilenio and the commuter train. The first selected line has a total of 34.5 km, 18 of them in the tunnel, 6 km half-buried, 10,5 in surface and a total of 33 stations.
The first metro line in Bogota (PLMB) has a length of about 27 km and will include 27 stations. All of it will be underground and it will be equipped with the most modern automatic train driving systems (UTO). The project was carried out under the aegis of the Institute of Urban Development (IDU), the official organism under the Capital District of Bogota. The estimated total investment (including trains, workshops and garages) amounts to about USD 6,900 million.
SENER developed between March and May 2015, a Value Engineering Study on this project for the National Development Finance Company (NDF) with the Government of Colombia, as co-financier of the project. The work has consisted in developing an analysis of the different aspects of the draft prepared by a consortium of engineering, in order to optimize its value. Using standardized methodologies (SAVE) and techniques developed by SENER, a team of experts identified a number of (non-binding) opportunities on the project, allowing a significant reduction in investment, operating and financial costs, as well as the commissioning period of the line. To achieve this goal SENER has sought to maintain a balance between the benefits provided, such as improving the efficiency of railway operation and the level of service passengers, employees and resources.
SENER has carried out this analysis from a life cycle perspective and addressing aspects of design, construction per phases, schedule and risk, thereby improving the socio-economic return on this high investment is fulfilling customer expectations.
