In 1954, preliminary and final surveys were carried out on the priority section Esil - Lomonosovskaya with a length of 95 km. The design assignment was completed on February 18, 1955 and approved by the Ministry of Railways on April 25, 1955.
The Atasu - Karazhal railway line was designed by Lentransproekt (since 1951 - Lengiprotrans) in the late 1940s. The road was supposed to provide access to an iron ore deposit in Kazakhstan.
Research, design and construction of the line were carried out on a tight schedule. In 1947, survey work began, and in April 1949 the technical design was completed.
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.

Privodino is a railway station of the Northern Railway in the Kotlassky District of the Arkhangelsk Region. In December 2004, an oil loading complex was built at the station.
Under the Lengiprotans project, the Privodino station was reconstructed to organize a railway loading station with a cargo turnover of 4 million tons of oil per year. Additional tracks were laid to ensure the reception of empty tanks, their supply to the railway tracks of the loading rack, the delivery of loaded tanks from the rack and their dispatch to the external railway network.
The Ust-Luga Commercial Sea Port is located in the Leningrad Region, in the Luga Bay of the Gulf of Finland of the Baltic Sea. The construction of the port began in the 1990s with the aim of creating powerful, high-performance complexes for transshipment of bulk cargo (coal, mineral fertilizers) to large-tonnage vessels with a carrying capacity of over 30 thousand tons.
Lengiprotrans designed a pre-port station and access railway lines to the new port in Luga Bay.
The Tosno - Malaya Vishera - Bologoye - Likhoslavl - Klin railway line is part of the Oktyabrskaya Railway.
