Passenger traffic on Budapest–Belgrade high-speed railway postponed due to software issues

The commencement of passenger traffic on the Budapest–Belgrade high-speed railway has been postponed. This delay is due to software issues within the train management system. A Chinese contractor is currently working to resolve these technical difficulties. While intensive testing has been conducted on the railway in recent weeks, the exact date for the resumption of passenger traffic is currently unknown.

Hungarian Minister of Transport and Investment David Vitezi stated that the delay shows that all competent organizations are seriously approaching the task of ensuring safety protocols are met. According to David Vitezi, passenger trains will not be included in the new railway timetable effective December 13. This contradicts previous announcements made by Serbian and Austrian railways, according to reports from Mondo.

Technical testing and safety standards

The Budapest–Belgrade railway is the first in Hungary to feature safety systems installed by a Chinese manufacturer that comply with European standards. Because of the complexity of these systems, the testing process includes the independent quality assurance organization TÜV. The inclusion of TÜV in the testing process was initiated by former minister János Lázár.

Following any minor corrections made to the system, the testing process will be repeated to ensure no errors remain. Passenger traffic will only begin once regulatory authorities, quality control organizations, and certification bodies confirm the safety systems function correctly. This rigorous approach aims to ensure that the new high-speed infrastructure meets all necessary safety requirements before it is opened to the public.

Future outlook for the railway line

The postponement means that the anticipated integration of passenger services into the regional transport network will face further delays. The current focus remains on the resolution of the software issues by the Chinese contractor. Once the technical issues are resolved, the project must still pass through multiple layers of regulatory and quality control oversight.

The project represents a significant infrastructure development for the region, linking Budapest and Belgrade with high-speed rail technology. The insistence on meeting European standards through the involvement of organizations like TÜV is a central component of the current testing phase. The project will only proceed to the passenger phase once all safety systems are verified as fully functional by the relevant certification bodies.
