Modernization of the Northern Railway Line | Portugal

Short Description

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.

Pinhal Novo Railway Station | Portugal

Short Description

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.
