Ivolga (train)

The Ivolga (named after "Иволга" bird, e.g. Eurasian golden oriole), designation EG2Tv and EGE2Tv, is an electric multiple unit passenger train produced and manufactured by Tver Carriage Works (TVZ) for urban and commuter service.

History
The exterior and interior styling, however, was outsourced: TVZ ordered the design of the concept train to Integral Design and Development (Arina Design) (Barcelona, Spain). A natural scale mock-up was built by Integral Design and Development and presented in Russia in 2015.

Re-styling of Ivolga was also outsourced to Integral Design and Development (Arina Design) in 2017. First Ivolga 2.0 trainset was built in 2019.

Since November 2019, an upgraded Ivolga 1.0 trains have been serving Line D1 of Moscow Central Diameters.

In 2021, yet another iteration of the design was presented, EGE2Tv, named Ivolga 3.0, with increased to 160 km/h max speed and meant for traveling longer distances. Whilst still utilizing the 2.0 exterior, the interior was updated by the Russian 2050.lab studio. They are currently meant for the new under-construction stage D3 of Moscow's MCD system planned to open in 2022-2023. First trainset was completed in 2022.

Next, Ivolga 4.0, would be an urban variant with 3 doors per car. First trainset was built in 2023.

Overall 41 trains of the type were produced so far, working on lines D1 and D2 of MCD Moscow's metro-rail (high-capacity urban-rail) system as well as on express route Moscow - Usovo.
