First 2 trains were in use on Moscow railways — Novoperedelkino express route in 2017 — 2018 before extension of the Moscow Metro  Solntsevskaya line.[1] Since 2018 they are working on Usovo branch of Belorussky suburban railway line in preparation for launch of Moscow Central Diameters D1 Line.[2]

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.[3]
