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

First 2 trains were in use on Moscow railways — Novoperedelkino express route in 2017 — 2018 before extension of the Moscow Metro  Solntsevskaya line. Since 2018 they are working on Usovo branch of Belorussky suburban railway line in preparation for launch of Moscow Central Diameters D1 Line.

The design, however, was outsourced to be "made in Europe": TVZ ordered the design and early development of the concept train to Integral Design and Development, S.A. company (Barcelona, Spain). A natural scale mock-up was built by Integral Design and presented in Russia in 2015.

In 2017 an update of this model was also outsourced to Integral Design; in 2019, first "Ivolga 2.0" train was constructed.

• Since November 2019, the upgraded models have been serving Line D1 of Moscow Central Diameters.
