The Kokchetav (Kokshetau) - Kzyl-Tu railway line is a section of the Kazakhstan railway. The project of the second tracks on the site was developed by Lengiprotrans by decree of the Central Committee of the CPSU and the Council of Ministers of the USSR in 1976-1985.
In the 1970s – 1980s, Lengiprotrans developed a project for second tracks with electrification on the Kokchetav (now Kokshetau) - Tselinnye Sands - Presnogorkovskaya section by decree of the CPSU Central Committee and the USSR Council of Ministers.
After the outbreak of the Great Patriotic War, the blockade of Leningrad and the cessation of traffic on a number of sections of the main passage of the October railway (the St. Petersburg - Moscow line), which ended up in the territory occupied by German troops, the need arose for a rockade railway.
"Lentransproekt" (1951 - "Lengiprotrans") worked out the options for the direction of the new railway line from the station Vesyegonsk of the Oktyabrskaya railway to the Kirov railway at different points of destination.
The Budogoshch - Tikhvin railway line is a section of the Tikhvin - Weimarn line of the Oktyabrskaya railway, passing through the territory of the Leningrad region.
The project of the railway line was developed by "Lentransproekt" (since 1951 - "Lengiprotrans") in the early 1940s with a military-strategic goal, as part of the "deep bypass" of the Leningrad junction. During the Great Patriotic War, the line provided the supply of the Leningrad Front and the protection of the city of Leningrad.
In the late 1980s, Lengiprotrans developed a project for on-farm highways in the Bryansk region within the framework of the Decree of the Central Committee of the CPSU and the Council of Ministers of the USSR dated February 29, 1988, No. 272 "On the state program for the construction and reconstruction of highways in the Non-Chernozem zone of the RSFSR."
The design was carried out on the basis of special regional norms and rules. Basically, these were highways between individual villages as part of state farms.
The Russkoye oil and gas condensate field (NGKM) is located in the Tazovsky region of the Yamal-Nenets Autonomous Okrug, beyond the Arctic Circle. The field, discovered in 1968, revealed 8 hydrocarbon deposits: 5 gas and oil, 2 gas and 1 oil.
In connection with the planned commissioning of the Russkoye oil and gas condensate field, Lengiprotrans has developed a project for a new railway line Russkoye deposit - Tikhaya.
Alytus is a railway station on the Šeštokai - Alytus line of the Lithuanian Railway.
In 1978 Lengiprotrans carried out design and survey work at the station. Longitudinal and transverse profiles were developed, and the lengthening of the railway tracks was designed.
The railway line Varena - Alytus is a former section of the Lithuanian railway. During Soviet times, Alytus became the industrial center of southern Lithuania, which required convenient transport links.
In the 1970s, Lengiprotrans carried out design and survey work on the Varena - Alytus section. A catalog of mine workings was compiled, well columns for artificial structures were designed, and topographic plans were prepared.
The Sosnogorsk - Troitsko-Pechorsk railway line is a section of the Northern Railway passing through the territory of the Komi Republic.
The project of the Sosnogorsk - Troitsko-Pechorsk line was developed by Lengiprotrans in the 1960s – 1970s. It was intended for the transportation of timber rafted along the Pechora River and processed at the constructed timber transshipment base in Troitsko-Pechorsk.
In 1961, the project assignment was approved by the Economic Council of the Komi ASSR. In 1975 the railway was put into permanent operation.
The Liiva - Lelle - Pärnu railway line is a section of the Estonian Railway connecting the capital of the country Tallinn (Liiva is part of the Tallinn junction) with the Baltic coast in Pärnu. The road was opened in the late 1920s with a narrow gauge of 750 mm.
The project of re-linking the railway section to a wide track of 1520 mm was developed by Lengiprotrans in the 1970s. This contributed to the creation of a direct route Riga - Tallinn with a length of 350 km.
