Modernization of the Northern Railway Line | Portugal
The Consortium led by COBA was in charge of the studies of section 1 between Lisbon and Entroncamento, of about 105 km-long. This section was sub-divided into three sub-sections: sub-section 1/1 - Braço de Prata-Alhandra, sub-section 1/2 - Alhandra-Setil and sub-section 1/3 - Setil-Entroncamento, for which distinct projects were carried out. The works began with sub-section 1/1, having the Technical Assistance of this subsection ended in 2000.
The project encompassed the track, the engineering structures, the flyover between Póvoa and Alverca, as well as stations and halts. Still within the scope of the modernization of the Northern Railway Line, a Maintenance Depot for tilting trains was designed at Contumil.

Sete Rios Railway Station | Portugal
The Project of the Sete Rios Railway Station Complex, carried out in a Joint-Venture, is part of the North-South Railway Link and is developed in the concordance zone with Campolide and the Sintra Railway Line.
The Railway Station Complex encompasses 2 railway viaducts
length of 220 m, 3 passenger platforms, one of which is central and the
other ones are lateral, built in the viaduct structure. The Passenger
Building covers an area of about 90 x 35 m² and comprises four floors,
the underpass on the West side and the East abutment, the deck and the
passenger platform covering and the plastic structure over the
viaducts, in the areas crossed by roads.

Dublin Metro | Ireland
The Irish Government launched, under a Public-Private Partnership regime, a design-build-operate tender for the Dublin Metro Northern Line, with a length of approximately 18 km, which connects the Dublin Airport to the city centre (Saint Stephen Green).
COBA was responsible for the geotechnical and structural
studies of 8 underground stations located in the Dublin urban area. The
stations, to be built under “cut-and-cover”, have a
maximum depth of approximately 30 m.

Pinhal Novo Railway Station | Portugal
The Pinhal Novo Railway Station is part of the expansion to the South of the existing railway infrastructure, in operation up to Fogueteiro, and interconnects the North/South Railway Link to the existing system, thus connecting with the Southern and Alentejo Railway Lines.
This intervention, within the scope of the remodelling of the railway infrastructure in Pinhal Novo, was subject to the constraints resulting from its location, as well as the other constraints associated to the fact that the operation of the line continued, in spite of the construction works.
The station is endowed with commercial areas and several meeting points.
