Srbijavoz has launched a 40-million-dinar public procurement for maintenance of its three Stadler KISS double-decker trains, known as Soko. Bids are open until 30 November.
The service covers the 410/418 series and includes fault diagnostics and repairs at the electric train depot in Zemun. The contractor must also provide out-of-hours technical support and a duty phone line for consultations.
Soko are the fastest trains in the country, running between Belgrade and Novi Sad.
