Here the warmer Ukrainian climate prevented the stations there from being severely deteriorated, which was why extensions in 1968 and 1979 were kept from going underground.

The line was once served by carriages of type D, which were later given to Saint Petersburg metro.

In 2014, some of the trains were refurbished and converted into type 81-7080/7081 or E-KM, with new engines, interior and exterior.

Since the line has the oldest stations in the system, some show heavy marks from nearly half a century of exploitation and need for renovations.

One of the which is Darnytsia which in the future is to become an important transfer station for three lines, has recently undergone a complete reconstruction, with an addition of a new western entrance.
