AŽD commissioned the StationSWing ESA 44-HU digital interlocking in two Hungarian stations on the line Szeged – Röszke – HU/SRB border, where AŽD acts as a subcontractor of R-KORD, part of V-Híd holding.

As part of the modernisation of the signalling equipment, AŽD installed a fully digital StationSWing ESA 44-HU digital interlocking system in Hungary, which controls traffic in the Szeged-Rendező and Röszke stations. The delivery also included the integrated line signalling equipment, level crossings, track circuits and the installation of the track side part of the ETCS level L1, which will be activated in the next phase of the project.
Both companies, AŽD and R-KORD, cooperated in Hungary on the development, production and installation of railway signalling. The cooperation included the application of Czech know-how and tools in the production of the final equipment in Hungary, as well as the development of software specifically adapted to Hungarian needs in accordance with the requirements of the Hungarian State Railways (MÁV Zrt.).
Installing digital technology at the two Hungarian stations is a “joint effort for adapting our digital systems to specific local requirements. We see obtaining the necessary technical approvals for operation in Hungary as an important step towards further opportunities in the region. We accept this milestone with humility and our goal is to convince the Hungarian State Railways that our systems are world-class,” said Zdeněk Chrdle, the CEO of AŽD.
The Szeged – Röszke – border with Serbia railway line is a strategically important corridor connecting Hungary to Serbia and the broader Balkans. The line is part of the historic regional rail network connecting Szeged (Hungary) with Subotica (Serbia), crossing the border at Röszke–Horgoš. It originally formed a single-track, non-electrified route constructed in the 19th century. The Hungarian segment covers approximately 12.6 km, while the Serbian side (Subotica through Horgoš to the border) runs about 26.6 km.
By equipping it with advanced digital systems, the project aims to improve operational efficiency and safety, prepare the infrastructure for ETCS deployment and support cross-border interoperability within the Trans-European Transport Network (TEN-T).
