The history of the line begins with the original Metro design plan, which despite numerous attempts could not make a provision to include the central railway terminal, something crucial for the Metro to become the city's main artery.
It was originally intended that in the mid -1990s the construction of the westward extension would begin, however with the lack of finances that plan had to wait for more than ten years before the new stations could finally begin opening in the 2000s.
Although the extension to Beryozovaya Roshcha was significant enough to end the shuttle regime on the line, the station was opened with only one tunnel complete.
The completion of the second one, originally intended for mid-2006, but offset to 2007 finally allowed for a standard regime to begin.
The line was expanded eastwards to Zolotaya Niva in 2010;[1] and further expansion is planned to Dovatora and Volochaevskaya.
