COMSA Corporación has been awarded a major railway contract by HŽ Infrastruktura to carry out the reconstruction, extension, and electrification of a 44-kilometer section of the M202 railway line in Croatia. Covering the stretch between Hrvatski Leskovac and Karlovac, the railway contract is positioned as a strategic upgrade to the country’s rail infrastructure, with a focus on improving its alignment with broader European transport corridors. The initiative is also expected to strengthen the digital supply chain by boosting the efficiency, throughput, and dependability of both freight and passenger services connecting key regional hubs.
Under this railway contract, the project’s engineering framework centers on expanding track capacity and enhancing operational speeds. A second track will be constructed alongside the existing line, enabling simultaneous two-way traffic flow. In parallel, new bridges and viaducts will be introduced, built to meet contemporary load-bearing specifications and designed to withstand high-speed operational vibrations. Once completed, the upgraded line will support train speeds of up to 160 km/h, significantly cutting travel times for regional and cross-border logistics movements.
The modernization effort also integrates advanced systems aimed at improving safety and operational control. Electronic interlocking and rail traffic management technologies will be deployed to optimize train headways and reduce collision risks. Additionally, the installation of overhead catenary systems will enable high-performance electric traction, contributing to lower emissions compared to diesel-based alternatives. Station and halt upgrades are also included, enhancing passenger accessibility while reinforcing operational safety standards across the network. These features collectively reinforce the technical depth of the railway contract.
This railway contract stands among COMSA Corporación’s most significant international undertakings and further cements its footprint in Croatia’s infrastructure sector. Since establishing operations in the country in 2015, the company has delivered multiple major railway developments, including the Gradec–Zabno line and the modernization of the Vinkovci–Vukovar section. The agreement was formalized by HŽ Infrastruktura Chairman Damir Loncaric and COMSA Director Pedro Miguel Rivero Moya, in the presence of Deputy Prime Minister Oleg Butković.
