As commissioned by the DSE Consortium, our Company prepared the detailed designs of the project and ensured the design engineer’s continuous presence and supervision on the site during construction.

The approval and tender designs were also prepared by our Company between 2005 and 2008 as commissioned by MÁV Zrt. and NIF Zrt.

The Kelenföld–Tárnok section of the Budapest–Székesfehérvár railway line is part of international corridor V, with long-distance passenger and freight traffic and, at the same time, a significant commuting component.

The electrified railway line was reconstructed from a single-track line to a double-track one. During the project, the infrastructure was completely refurbished. The connecting track No. 31 between Érd junction and Tárnok was also reconstructed under the project.

On the reconstructed line, the speed and axle load increased and the stations and stops were upgraded.

In addition to making the line accessible for the disabled, P+R car parks were constructed and level crossings, bridges, culverts and subways were upgraded.

The catenary, telecommunications, area lighting and power supply networks and the signalling system were also upgraded.
