Teano
station

The project of the station has taken into account the future branching of Line C towards Serenissima, known as “Line C1,” which has determined the arrangement of the overlapping platforms and the construction of an additional structure where the connections with the future C1 branching are planned.

The underground portion of the station has an almost rectangular footprint with dimensions of 107.50 x 30 m and a depth of approximately 30 m (33 m in the depression of the drainage basin). At the atrium level alone, the station has an “L” shape because the deep station structure is joined by the connecting corridor of the atrium to the exits on Viale Partenope, with an excavation depth of about 7 m and dimensions of 34 x 85 m in plan, excluding the ramps. The C1 branching structure adjacent to the station has a flared shape with a length of 89 m and a variable width between 13 and 31.5 m and an excavation depth of about 30 m. The initial diaphragm walls of the C1 branching were constructed using a grab bucket, later replaced with an hydro-mill. The depth of the diaphragm walls is 40 m for the station structure and the C1 branching and 19 m for the exit structure under Viale Partenope.

Station Levels

The above-ground structure of the entrance area, with a plan dimension of approximately 40 x 36 m and variable height ranging from 4.5 m to about 8.90 m, is constructed with a framework consisting of a double set of metal beams supported by metallic pillars placed on two sides. The roof is made of white-painted steel, enclosing the continuous steel and glass facade. The station is developed over 6 underground levels, in addition to the roof and foundation slabs. There is a lobby level, a first technical level, the platform level for the even track with its sub-platform, a second technical level, and the platform level for the odd track.

The station structure was constructed using the top-down method until the bottom slab. The completion of the station was carried out from bottom to top, including the installation of the waterproofing layer between the diaphragm and the inner lining before the construction of the latter.

Station Entrances

The station has four entrances, with two on the platforms of Viale Partenope, symmetrically positioned relative to the axis of the road. Each of these entrances is equipped with an escalator and a fixed staircase in series with each other. The other two entrances are located at the front and rear of the station’s above-ground structure, connecting the street level to the atrium level via a fixed staircase and an elevator.

The original surface arrangement of the station included a rethinking of the adjacent road system in anticipation of constructing an underground parking lot and an at-grade parking area for the station. The abandonment of this project meant that the external works were limited to the areas affected by the construction, with a restoration of the pre-construction state and the creation of access roads to the above-ground structure.

Architecture

The design of the Teano station was entrusted to the architectural firm Archigroup sas. The defining element of the station is undoubtedly the continuous facade of the above-ground structure with its visible curved roof from Teano Street. It also serves as a reference point for those coming from Viale Partenope and provides natural light to the underlying atrium. The exits on Viale Partenope are defined by reinforced concrete walls and signaling totems covered with beveled travertine slabs laid in a continuous pattern.

The finishes of the station follow the standards of Metro C stations. The flooring is in anthracite-colored porcelain stoneware, and the cladding is in white glass, both topped with the signal band. The atrium floor features a spacious area beneath the glass roof, designed as an exhibition space for temporary or permanent cultural events.
