Applications for train paths have reportedly been submitted to Czech infrastructure manager SŽDC and its Slovakian counterpart ŽSR for the services, which are expected to begin operating in December.

Dual-voltage locomotives capable of operating under 3kV dc and under 25kV 50Hz ac electrification systems would be required for the 396km route. RegioJet is already leasing Vectron multi-system locomotives from Vienna-based European Locomotive Leasing.

Previously Regiojet sought to introduce a Prague - Brno service on part of the same route, but this was vetoed by Czech Railways (CD), which operates long-distance services between the two cities under its contract with the Czech government. However, under European law cabotage rules apply to cross-border services which would enable Regiojet to serve Brno.

Regiojet already operates in Slovakia, with international trains from Prague and Ostrava serving Košice and domestic open-access long-distance services between Košice and Bratislava. Regiojet also operates regional services on the non-electrified Bratislava - Komarno line under a contract with the regional government.
