The Norilsk Railway is an isolated railway network in the north of the Krasnoyarsk Territory. It is one of the northernmost steel lines in the world.
In the 1980s, Lengiprotrans prepared a project for the electrification of the Norilsk railway by order of the USSR Ministry of Nonferrous Metallurgy. The line was electrified with 3.3 kV direct current. By 1985, the electric sections were completely replaced by the ER1 and ER2 electric trains.
Rybatskoye - Polyany - a section on the Volkhovstroevsky direction of the October railway.
In the post-war period, Lengiprotrans developed projects for the restoration of destroyed signaling and communication devices on the approaches to Leningrad, in the Baltic States and Belarus. The objects carried out during this period include semi-automatic blocking at the Rybatskoye - Polyany section with the reconstruction of mechanical interlocking at the Rybatskoye, Torfyannoye, Dubtsy stations, including the Chudovsky railway junction.
Makushino - Omsk - Novosibirsk is a section that is part of the South Ural and West Siberian railways.
During the Great Patriotic War, the specialists of Lentransproekt (since 1951 - Lengiprotrans) performed design work on signaling and communication devices on the Makushino - Novosibirsk section. The carrying capacity of the line was increased to ensure the supply of the country through the Far East and transportation during the subsequent war with Japan.
Railway line Mudyuga - Kem - a section that is part of the Northern and Oktyabrskaya railways.
The project for the suspension and sealing of the colored chain on the line was prepared by Lengiprotrans in 1956. In the same period, similar work was carried out at the Nyandoma - Mudyuga section.
Leningrad-Varshavsky is a former station of the October railway in St. Petersburg, founded in 1853. From here, trains departed for the Luga and Baltic directions.
In 1960-1966, according to the Lengiprotrans project, the station was reorganized in connection with the electrification of suburban traffic on the Leningrad - Gatchina-Baltiyskaya - Siverskaya section. At the station, work was carried out to reconstruct the apron tracks, in which the landing stage was eliminated and the tracks located under it were removed.
Leningrad-Varshavsky - Shosseinaya - the former head section of the Varshavskaya line, which ran from the former Varshavsky railway station to the south of St. Petersburg.
The Piskarevka - Ruchyi section is a connecting line of the Oktyabrskaya railway in the Kalininsky district of St. Petersburg.
In the late 1960s - early 1970s, according to the Lengiprotrans project, second tracks were built on the site in order to increase the capacity. This was also due to the construction of a road overpass in the alignment of Piskarevsky Prospekt above the station tracks in the early 1960s.
The Piskarevka - Rzhevka section is the connecting line of the Oktyabrskaya railway within the boundaries of St. Petersburg.
The single-track section Piskarevka - Rzhevka for a long time remained a "bottleneck" that impeded intensive commuter traffic. In 1986-1987, according to the Lengiprotrans project, the second main track was laid here. As a result, all railway approaches to Piskarevka station became double-tracked.
The Kirov railway junction is located on the Gorkovskaya railway and is part of the Trans-Siberian Railway. Passenger and freight traffic of the boiler, Glazov and Kotlas directions passes through it.
The project for the power supply of the railway junction was prepared by Lentransproekt (since 1951 - Lengiprotrans) in 1940-1950. As part of it, the Lyangasovo junction railway station, located in the eponymous district of the city of Kirov, was electrified.
The Dno is the junction station of the October railway. The directions St. Petersburg - Vitebsk and Rybinsk - Bologoye - Pechory-Pskovskie pass through it.
In 1940-1950, a power plant was built at the station according to the project of Lentransproekt (since 1951 - Lengiprotrans).
