Railway Sections in Romania

FCC is executing the rehabilitation and improvement of three railways sections along the Brasov - Simeria line, which forms part of the Pan-European transport corridor IV in Romania.

SIGHISOARA-ATEL SECTION

These works are included in the Brasov – Simeria railway line rehabilitation plan in Romania, which forms part of the PAN-EUROPEAN corridor IV for railway traffic, with a maximum speed of 160 km/h. The Sighisoara-Atel section runs through the provinces of Mures and Sibiu. The total project is 94.75 kilometres long, of which 28.22 kilometres correspond to the reference section.

The section to be rehabilitated is double, electrified track. The jobs included in the project are as follows: earth movement works, consolidation, superstructure, bridges, overpasses, underpasses with prefabricated elements, line electrification, electric power, lighting, railway telecommunications, civil construction, roads and highways and environmental protection.
