Belfry PE – Railway construction

Railway construction 

Belfry PE covers four sectors, amongst these the railway business generates the largest revenue. It participates in substantial projects in Hungary.  The company has to overcome considerable and complex challenges, for instance the refurbishment of underground line no. 3, where subcontractors of different profiles has to be coordinated and managed. The Tram-Train is another example where such technical expectations has to be met which are rare, even in Europe. The railway and tram traffic have to be aligned with the construction process. It means that the safe cooperation has to be worked out and ensured in consideration of different standards.



Railway line no. 2 – Rákosrendező station – Esztergom station overhead line development. The complete refurbishment of the Rákosrendező – Újpest station and Esztergom station, the development of the intermodal hubs in Dorog and Esztergom, and the reconstruction of the connecting road network.

The Strabag-Belfry consortium executed the following works in accordance with the contractual terms:

  • Esztergom station: Development of the arrival tracks for freight trains. Removal of the lead tracks in the passenger station area, installation of buffers, the reconstruction of the rail network, partially on-site.
  • Refurbishment of the station building of Esztergom station: Refurbishment of the station building in accordance with the design plans attached as part of volume 5. Platform roof installation between tracks II and IV. Signalling control building development. Partial installation of the underground cables.
  • Relocation of the bus station to next to the train station in Esztergom.
  • Road works, installation of the platform roof and development of the new station building of the Volán bus station. Warehouse building and a new passenger building development.
