The line was opened on 21 November 2019, at the same day as D2. It uses the tracks and the stations of the Savyolovsky and the Belorussky suburban railway lines. The length of the line is 52 kilometres (32 mi), and the travel time between the termini is 80 minutes.[1] These suburban directions have been connected earlier, and through suburban trains were running between them, therefore the initial investment to open the line was minimum.[2]

Modified Ivolga trains have been serving the line since its opening with EP2D (Russian: ЭП2Д (Электропоезд Пригородный 2 тип Демиховский) trains.[2]
