TRAZA, a consortium made up of FCC Construcción, TUZSA, Acciona, CAF, Ibercaja and Concessia, is the provisional winner of the Zaragoza City Council's tender to select a partner for the combined public/private company that is to be given the assignment of building, starting up, maintaining and operating Line 1 of the Zaragoza tram system for 35 years.
The tram line will run between the end points of Parque Goya and Valdespartera. It will be a total of 12.8 kilometres long and will have 25 stops. Trams will take a total of 40 minutes to cover the route from end to end and are expected to be up and running in 2013.
The project involves an initial investment of approximately 340 million euro, 130 million of which will be provided in equal shares by the Zaragoza City Council and the Regional Government of Aragón. When the job is complete, the city will be equipped with the most modern tram in all of Spain.
The work at issue is the construction of a ground-level railway bed for twin electrified tracks crossing the city of Zaragoza from north to south.

This will be done in two consecutive phases:
• Phase 1 (Valdespartera to Gran Vía)
• Phase 2 (Gran Vía to Parque Goya)

In addition the design calls for the construction of two coach shed and shop areas, one for each phase, plus two parking lots and an intermodal transfer point. The contract includes the supply of rolling stock and all equipment.
The winning bid, TRAZA, features CAF's URBOS III-model trams, which will be made at the CAF plant in Zaragoza. These vehicles are 33 metres long (and can be lengthened to 43 metres) and 2.65 metres wide. Each set-up is able to accommodate 200 passengers, including 54 seated passengers. These trams have a special low floor, giving people with reduced mobility full access. The maximum speed will be set at 50 kilometres per hour, although the vehicles' commercial speed (average speed including stops) will be 19 kilometres per hour.
As established in the specifications, the central portion of the tram route, between Gran Vía and Puente de Santiago, will not be equipped with a catenary. To comply with this requirement, the TRAZA bid includes the ACR fast-charging battery system, which allows trams to accumulate enough energy at each stop to reach the next stop. In addition, these trams will recover energy when braking, which means they will save up to 35% of the power they need to operate.
