Currently used exclusively by freight trains, the 54km Moscow Ring Railway has been upgraded for suburban passenger services. Work began on the project in 2013 and involved electrification of the entire line at 3kV dc, construction of new stations, addition of a third track on the northern section of the line, and construction of a new depot at Podmoskovnaya. Testing using the ES2G fleet is now underway on the line and passenger services are due to begin operating on September 10.
