The Budapest–Belgrade railway recently underwent its most comprehensive test to date, successfully operating trains at speeds reaching 160 km/h. This testing phase simulated typical peak-hour conditions to assess the railway’s performance under pressure. The successful completion of this test signifies a major advancement towards the anticipated launch of passenger services on the line. The Budapest–Belgrade railway project has been long-awaited, promising improved connectivity between Hungary and Serbia. This development is expected to significantly reduce travel times, fostering economic and cultural ties. Further details regarding the launch date are forthcoming, but this trial indicates the project is nearing completion. The trial run brings the project closer to its ultimate goal of modernizing rail transport between Budapest and Belgrade.
