Railway line Delyatyn - Rakhov - state border - section of the Lvov railway.
The project of strengthening retaining walls, subgrade and structures on the section Delyatin - Rakhov - state border was developed by the Department of Engineering Geology "Lengiprotrans" in 1976-1981.
Ventspils is the largest ice-free port on the Baltic Sea in Latvia, specializing in the export of oil and oil products. In the 1950s – 1970s, 3 stages of the Ventspils transshipment oil depot were built here.
In the period 1956-1970, the Department of nodes and stations of Lengiprotrans developed more than 20 author's projects for the development of external railway transport of industrial enterprises, industrial zones and ports. In particular, the external railway transport of the oil depot in Ventspils was designed.
Железнодорожная линия Комсомольск-на-Амуре — Советская Гавань является восточным участком БАМа. Она была сооружена в годы Великой Отечественной войны с целью переброски войск и снаряжения на Дальний Восток России, необходимых для ведения войны с Японией.
The Baikal-Amur Mainline, built in the 20th century, is still one of the largest transport construction projects in the world. "Lentransproekt" (since 1951 - "Lengiprotrans") from the moment of its formation took part in the design of the BAM. Design and survey work at BAM has a long history, consisting of several stages.
In 1937 "Lentransproekt" organized a complex expedition to carry out the final surveys of the Bureya (Ust-Niman) - Komsomolsk railway line. 6 complex parties worked on the track, including tunnel and hydrometric ones.
During the Great Patriotic War, with the participation of Lentransproekt employees (since 1951 - Lengiprotrans), the Stalingrad - Saratov - Sviyazhsk railway line was designed and built to solve the most difficult problem of delivering material resources to the Stalingrad Front.
Kokchetav (Kokshetau) - Novoishimskaya - a section of the former Tselinnaya railway.
The site was electrified using a 2x25 kV AC system under the Lengiprotrans project in the 1980s.
Peski-Tselinnye (now Novoishimskaya) - Presnogorkovskaya - a section of the Presnogorkovskaya - Pavlodar line of the Kazakhstan railway.
The project for electrification of the site was developed by Lengiprotrans in the 1980s. In the same period, the institute designed the second tracks on the line Kokchetav (now Kokshetau) - Peski-Tselinnye - Presnogorkovskaya.
The electrification of the section Kokchetav (now Kokshetau) - Tselinnye Sands (now Novoishimskaya) was developed by Lengiprotrans in 1983. The site was equipped with a contact network.
Within the title were projected:
• at the station Peski Tselinnye: traction substation;
• at Yanko station: traction substation, the main building of the contact network duty station, ground storage of fuels and lubricants, material storage, reinforced concrete pipe; low passenger platforms;
The railway line Leningrad - Zelenogorsk - Roshchino - Vyborg is the main section of the Vyborg direction of the Oktyabrskaya railway.
In the 1950s – 1960s, Lengiprotrans participated in the design of the electrification of the suburban sections of the St. Petersburg railway junction. During these years, the Leningrad - Zelenogorsk - Roshchino line was electrified, and later the electric traction was brought to Vyborg.
The Vyborg - Kamennogorsk - Svetogorsk railway line is a section of the Oktyabrskaya railway in the Vyborg district of the Leningrad region. The line carries out cargo transportation in the direction of Finland.
The electrification of the Vyborg - Kamennogorsk section, 120 km long, was planned back in the 1980s, but was not implemented.
The electrification project for the Vyborg - Kamennogorsk - Svetogorsk section was developed by Lengiprotrans in the 1990s.
