The overall objective of the project was to promote rail mobility along Pan-European Corridor IV through the rehabilitation and upgrading of the existing line from Brașov to Simeria.

The project was carried out while ensuring the continuity of rail operations and involved the renewal of the track infrastructure and technical systems, the renovation of structures (bridges, culverts, and stations), as well as the construction of new rail lines alongside the existing ones and new engineering structures (bridges and culverts).

This upgrade resulted in an increase in the maximum speed of passenger trains to 160 km/h and freight trains to 120 km/h, as well as improved transport safety and environmental protection. Specifically, the project concerned Lot 2, the Coșlariu–Vințu de Jos section, with a total length of 33 km. This lot is part of the Coșlariu–Simeria section, which in turn is part of the Brașov–Simeria line.
