The service started on December 12, 2010. The aim was to reduce travel time between Helsinki and Saint Petersburg: before Allegro, the journey time was 5½ hours; it became 3 hours and 27 minutes over a journey of and there were plans to bring it down to 3 hours. The name
Allegro is a musical term for a quick
tempo, thereby suggesting "high speed". On board the inaugural service were Finnish president
Tarja Halonen and Russian prime minister
Vladimir Putin. The service was suspended between March 18, 2020 and December 11, 2021 due to the
COVID-19 pandemic. Service resumed with restrictions on December 12, 2021. During the
2022 Russian financial crisis, in the aftermath of
international sanctions placed on Russian companies following the
2022 Russian invasion of Ukraine, the Allegro train became a primary means for people to leave Russia. As European airspace had been closed to Russian planes, and Russian airspace was closed to European planes, the train was the only passenger connection between Russia and the
European Union. EU authorities asked VR to keep this train running so that those wishing to leave Russia could do so (though as part of
COVID-19 restrictions, only Finnish and Russian citizens were allowed to use the train, and it ran only twice a day at half-capacity, of 327 passengers; but operators worked to lift those restrictions in order to allow the evacuation of other nationals). The service was suspended on March 27, 2022 due to the aforementioned sanctions. In December 2023, it was announced that VR Group had assumed the financial obligations of the joint stock company that used to run Allegro since it could no longer meet them itself. VR Group plans to reuse the rolling stock in domestic operations. ==Route==
