La Garena station, in the municipality of Alcalá de Henares, is located on the C2 line of the Madrid commuter train line (Atocha-Guadalajara). It is included in the Partial Plan of the Programmed Developable Land Sector 101 “La Garena” and in the Urbanization Project that develops it.

The intervention solves the passenger interchanges of the ffcc and the connection between the urban areas separated by the tracks. The response to both needs is solved jointly, placing both the pedestrian walkway and the station concourse in the same structure under the tracks.

The structure is resolved with two families of metallic elements: the first with three transverse arches to the passage on which the secondary structure is supported by straight profiles according to the generatrices that are also supported on the slab of the building. Hanging from one of the arches and following the generatrices of the enclosure cylinder are profiles and suspenders.

The former serve to support the closing tramex. A curved walkway hangs from both of them, from which the folding doors that delimit the access to the station are hung.

The structure is clad on the top with “Kalzip” type ribbed aluminum sheeting, except for a lower glazed strip that allows direct light to enter the entrance hall. The interior is clad with white aluminum louvers.

The problems posed by the construction of this station were on the one hand its depressed location with respect to the natural terrain, on the other hand the presence of water due to the high water table and finally the need to cross under four ffcc tracks whose traffic cannot be interrupted.
