New Arganzuela-Planetario station
Here you will find information, graphic documentation, photographs, etc. of this work.
Commissioning: January 26, 2.007
It is located on Line 6, in the Arganzuela district, south of Madrid. The work limits to the north with c/Párroco Eusebio Cuenca, to the south with the new layout (extension) of c/Antracita, to the east with Parque Tierno Galván and to the west with c/Bronce. Part of the project is the construction of two complementary ventilation shafts between the Legazpi station and the new Arganzuela-Planetario station and between the Méndez Álvaro station and the Arganzuela-Planetario station.
Also part of the area called the station is a depot or siding for the incorporation or withdrawal of trains according to the needs of the service, as well as a workshop at the level of the tracks. In the future, on this level, and above street level, a Metro command post will be built.
As of the “Pasillo Verde” operation in 1995, the reclassification of industrial land to residential land in the area where the station is located was ordered. As of this operation, a ten-year moratorium was given to the companies that existed in the Legazpi industrial estate for their transfer.
With the completion of the Vía Verde, part of these areas became buildable, and the rest, as well as uninhabited sections, were incorporated into the Tierno Galván Park, where various recreational facilities have been built, such as the Planetarium and the IMAX cinema. The construction of numerous housing developments caused a significant increase in the population, which became residential and made up of young families.
The construction of the new Arganzuela-Planetario station constitutes a clear improvement in the functionality of Line 6. This possibility had already been contemplated in the original project, in which an area with a horizontal grade had been established, prepared for the construction of a back station.
The district has been equipped with basic facilities such as schools, health centers and a sports center. In addition, next to the station, in c/Bronce, the works of a new school, the CPTirso de Molina, have already been carried out.

On the lowest level, in addition to the platforms, there are depots for Metro rolling stock, for which the corresponding track and catenary works are carried out.
The extraction of materials from the excavation inside the enclosure is carried out by two lateral ramps made between piles.
These ramps are progressively excavated as the level of excavation inside the station is lowered.
When the excavation was close to the existing Metro tunnel in service (Line 6). The line was cut in order to demolish the segments of the tunnel and continue with the excavation.
Before beginning the work during the cut of the line, in the days prior to the suspension of the service, everything that could be done without affecting the Metro service was executed; For this, the maximum emptying of the station was carried out in order to reduce the execution period in the cut-off dates.
The emptying was carried out in two phases (see sketch 1):
- Phase 1: It is carried out before the cut of the metro line, it includes zones 1,2, 3 and XNUMX.
- Phase 2: It is carried out during the cut of the metro line and includes zones 4 and 5 and the demolition of the width and voussoirs.
Once the tunnel voussoirs had been demolished and the ground had been excavated, the counter-vault that served as support for the track and the execution of the station platforms were poured. The track was then restored, giving service to the Metro line. These line cutting works were carried out in a period of less than two months.
Once the slabs had been executed, and trains were already circulating, the masonry and installation phase was carried out, which will make it possible to create each of the dependencies and entrances required by a Metro station.
Ventilation shaft construction activities
The procedure basically consists of:
- A perimeter of pile walls (Well).
- Stampers with periodic spacing, carried out as the excavation is carried out.
- Underground tunnel made by the Madrid Method until reaching the current line (Gallery).
- Realization of the reinforcement of the union and demolition of the voussoirs of the existing tunnel.
