The opening of M3 metro line was in 1976, based on old Soviet constructions. Since, there wasn’t any renovation, it’s operation was a total chaos. The old, rusty trains lit up on weekly basis, there were evacuations, closures. In the last few years, it was an everyday topic in the media, that leaders doesn’t care about people may die while using it. Finally the government decided to modernize it, to meet 21th century needs. The restoration of old M3 metro line started on the 4th of November 2017, and will last for 3 years at least.
