Train operators in Slovakia

The railway infrastructure of Slovakia is maintained by Železnice Slovenskej republiky (or ŽSR for short) while the the state-owned national rail operator for passenger trains is Železničná spoločnosť Slovensko (ZSSK). However, a good number of both long-distance and regional trains are run by other operators. A unified tariff and timetable system administered by ŽSR ensures a smooth move between each operator's trains.
