After the rack-and-pinion railway in Vysoké Tatry (Ozubnicová železnica, OŽ) was cleared of snow on Friday 11 February, test runs began the very next day.
For 16 February 2022, it is planned to start passenger operation on the rack-and-pinion Štrba - Štrbské Pleso line in Vysoké Tatry.
Since July 2020, Strabag and Swietelsky-Slovakia carried out the modernisation of the OŽ line (Ozubnicová železnica, Rack and pinion railway) in Vysoké Tatry. On 23 July 2021, the Special Construction Office of the Slovak Ministry of the Interior issued a permit for "early use of the line - for test runs".
In early August, testing of the new Stadler-built Class 495.95 EMUs started on the rack railway between Štrba and Štrbské Pleso.
In connection with the forthcoming replacement of RegioJet by jointly operating ZSSK and ÖBB on the Bratislava - Komárno line from 12 December 2020, the first test runs of „new“ vehicles envisaged for these services took place there.
