In 1950–1960, the electrification of the suburban sections of the Leningrad railway junction was widely carried out in accordance with the 1956 decree "On the general plan for the electrification of railways." During these years, the suburban line Lanskaya - Sestroretsk - Beloostrov was electrified under the Lengiprotrans project.
Later, in the process of introducing new achievements in the field of automation, telemechanics, communications and radio, a semi-automatic blocking with traffic light signaling was designed on the line.
In the 1970s, the Lanskaya - Sestroretsk - Beloostrov electrified section was transferred to telecontrol. The technical project provides for the transfer of the control of the automatic blocking line disconnectors from the "Neva" dispatching centralization system to the EST-62 telemechanics system of the energy dispatching circle using equipment and cable lines to control the disconnectors.
