The Kursky suburban railway line (Russian: Курское направление Московской железной дороги) is one of eleven railway lines used for suburban railway connections between Moscow, Russia, and surrounding areas, mostly in Moscow Oblast. The Kursky suburban railway line connects Moscow with the stations in the south, in particular, with the towns of Podolsk, Chekhov, Serpukhov, Yasnogorsk, and Tula. The stations the line serves are located in Moscow, as well as in Podolsk, Chekhov, and Serpukhov in Moscow Oblast, as well as in Zaoksky and Yasnogorsky Districts and the city of Tula in Tula Oblast. Some of the suburban trains have their northern terminus at Moscow Kursky railway station in Moscow, others commute from the Rizhsky suburban railway line. In the southern direction, the suburban trains terminate at Krasny Stroitel, Shcherbinka, Podolsk, Lvovskaya, Chekhov, Serpukhov, and Tula I.^[1] The line is operated by Moscow Railway. The tracks between Moscow Kursky railway station and Podolsk are also used by Line D2, one of the Moscow Central Diameters.

The suburban railway line follows the railway which connects Moscow with Kursk and Belgorod and further with Kharkiv. It is electrified and has two tracks everywhere between Moscow and the Ukrainian border.^[2] The distance between Kursky railway station and Tula I is 194 kilometres (121 mi).
