Railway line Melnichny Ruchey - Nevskaya Dubrovka - a section of the Irinovskaya direction of the Oktyabrskaya Railway (OZhD).
The section Melnichny Ruchey - Nevskaya Dubrovka was electrified with DC voltage of 3 kV according to the Lengiprotrans project in 1967. As a result, the Irinovskoye direction of the OZhD was finally transferred from diesel to electric traction.
Railway line Melnichny Ruchey - Ladozhskoe Lake - a section of the Irinovsky direction of the Oktyabrskaya railway. During the Great Patriotic War, she served the Road of Life ice crossing for communication with the besieged Leningrad.
The section Melnichny Ruchey - Ladozhskoe Ozero was electrified with DC voltage of 3 kV according to the Lengiprotrans project in 1966. For the opening of the movement of electric trains on the line, the railway track was reconstructed, platforms and pavilions were built at 3 stations and 6 stopping points.
Railway line Leningrad - Melnichny Ruchey - a section of the Irinovsky direction of the Oktyabrskaya railway. In the 1892-1920s, the Irinovskaya narrow-gauge railway passed along this direction.
In the 1950s, Lengiprpotrnas developed a project for the electrification of the Leningrad - Melnichny Ruchei section using a DC voltage of 3 kV. Semi-automatic blocking with traffic lights was designed on the line.
The Leningrad - Malaya Vishera railway line is the current section of the main course of the Oktyabrskaya railway Moscow - St. Petersburg.
In 1960, the line was electrified according to the Lengiprotrans project as part of the transfer to electric traction of the Moscow - Leningrad route. Also in 1961, according to the project of the institute, a branch with a length of 20 km from the Tosno station of the Leningrad-Malaya Vishera line to the Shapki station was electrified. All sections are electrified for DC voltage of 3 kV.
Railway line Leningrad (now St. Petersburg) - Peri - Vaskelovo - a section of the Priozersky direction of the Oktyabrskaya railway.
In the 1950s, Lengiprotrans developed a project for the electrification of the line in 2 stages. On the Leningrad-Peri section, a semi-automatic blocking with traffic lights was installed.
The Vologda - Danilov railway line is a section of the Northern Railway.
The road was built in the second half of the 19th century, and in the late 1930s Lentransproekt (since 1951 - Lengiprotrans) designed the second tracks on it.
Later, according to the project of the Institute, the electrification of the line was carried out.
The Velikie Luki Steam Locomotive Car Repair Plant (PVRZ) is an enterprise for the repair of various freight cars for the needs of railway transport. Its history begins with the arrival of the Moscow-Vindavskaya railway in Velikiye Luki in 1901, when the Main Railway Workshops for the repair of locomotives and carriages were created. In 1927, on the basis of workshops, the Velikie Luki steam locomotive repair plant was created.
Daugavpils Steam Locomotive Car Repair Plant (PVRZ) was founded in 1866 in connection with the emergence of railways. The company specializes in the repair of diesel locomotives and electric trains of various series.
In 1940-1950s Lengiprotrans developed a project for the restoration of the Daugavpils PVRZ, which was destroyed during the Great Patriotic War. Also, the Electrification Department of the Institute developed an author's design of a combined heat and power plant (CHP) at the enterprise.
Railway line Kizel - Perm - a section of the Sverdlovsk railway. In the late 1940s, Lentransproekt (since 1951 - Lengiprotrans) developed a project for its electrification.
During the design, the following most interesting solutions were developed:
• Application of end-to-end recuperation with the installation of inventory units at traction substations.
The Novosibirsk - Chulymskaya railway line is a section of the West Siberian railway.
In 1940-1950s Lengiprotrans developed a project for the electrification of the line. An automatic blocking was installed on the railway section.
The electrification of the railway contributed to the development of the city of Chulym. As a result, the transport enterprises and the railway station were reconstructed, the industry was electrified, the construction of a locomotive depot, forestry enterprise and a car fleet began.
