The GV 90, also called the AV GV 90, is a Ruvelkan electric tilting train operated by the Ruvelkan State Railway. Beginning operation in 1990, it is the flagship high-speed train of Ruvelka and was initially a first-class only line that connected the nation’s two largest cities of Debrecen and Székesfehérvár. The initial success of the GV 90 led the State Railway to expand it’s high-speed rail network which led to the introduction of second-class seats in 1993. Over the course of six years, the GV 90 lines later expanded to include the cities of Mátészalka, Hajdúböszörmény, Aszód, and Derecske with major depots in Debrecen and Székesfehérvár.
Six train sets of the GV 90 family played a critical role in evacuating civilians from Aszód during the early days of the Zemplen War, effectively running non-stop between Aszód and Székesfehérvár before the rail lines connecting Aszód to other cities were eventually destroyed. Two of the sets, which were strandend in the city after the rail lines were rendered inoperable, were destroyed during the siege of Aszód with the remaining four placed in storage in Székesfehérvár. After the war ended, the four surviving train sets, which had affectionately been nicknamed “lifelines” by those who rode them to escape, were permanently assigned to the Székesfehérvár-Aszód route with all four eventually taking up the names of Ruvelkan war heroes.
Beginning in 2011, the GV 90 rolling stocks underwent a refurbishment program which would significantly extend their service lifespans with the final unit returning to service in 2016.
