The Leningradsky suburban railway line (Russian: Ленинградское направление Октябрьской железной дороги) is one of eleven railway lines used for suburban railway connections between Moscow, Russia, and surrounding areas in Moscow Oblast and Tver Oblast. The Leningradsky suburban railway line connects Moscow with the station in the northwest, in particular, with the towns of Khimki, Zelenograd, Solnechnogorsk, Klin, Konakovo, and Tver. The stations the direction serves are located in Moscow, in the towns of Khimki, Solnechnogorsk, and Klin in Moscow Oblast, and in Konakovsky and Kalininsky Districts and the city of Tver of Tver Oblast. The suburban trains have their southeastern terminus at Moscow Leningradsky railway station in Moscow. In the northwestern direction, the suburban trains terminate at Kryukovo, Podsolnechnaya, Klin, Konakovo GRES, and Tver.[1][2] The line is served by October Railway. This is in contrast to all other suburban directions from Moscow, which are served by Moscow Railway.
The suburban railway line follows the Moscow – Saint Petersburg Railway which connects Moscow with Saint Petersburg via Tver and Bologoye. It is electrified everywhere between Moscow and Saint Petersburg.[3]
