The government plans to purchase 42 modern, 120-meter-long motor units for the H5 Szentendre, H6 Ráckeve and H7 Csepel lines using repatriated European Union funds. The first new vehicles are expected to enter service from 2030.

Minister of Transport and Investment Dávid Vitézy said that despite the state taking over HÉV operations more than a decade ago, no meaningful development had taken place, even as tens of thousands of people moved to suburban areas served by the lines.

He added that earlier modernization plans were halted when the former ministry canceled HÉV development.

The new trains will be accessible and air-conditioned and are expected to provide faster, more reliable service. The procurement process is scheduled to begin before the end of 2026, paving the way for a full fleet renewal within the decade.
