Construction Department "Pechorstroy" is a construction company that was founded in 1940 in connection with the need to build the North-Pechora railway to transport Vorkuto-Pechora coals.
The Pechorstroy production base in the city of Pechora was built according to the Lengiprotrans project in 1971-1975.
Pechorstroy took part in the construction of many railway lines designed by Lengiprotrans in the North-West of Russia: Mikun - Syktyvkar, Mikun - Koslan, Synya - Usinsk, Karpogory - Vendinga and Chinyavoryk - Timan.
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 Ülemiste - Maardu railway line is a connecting section of the Ülemiste - Muuga railway in Estonia.
In the 1980s, Lengiprotrans was engaged in the reconstruction of the site to create convenient approaches to the seaport of Muuga.
In 1983, during the survey, groundwater analysis was carried out, mine workings and well columns were prepared.
In subsequent years, the site was designed:
• double-circuit high-voltage line 10 kV and low-voltage networks;
• auto-blocking and automatic cleaning of switches from snow;
The Shotkusa-Megrega railway line runs in the North-West of Russia, through the territories of the Leningrad Region and the Karelian Republic.
The railway line was built according to the Lengiprotrans project in the 1970s.
Pärnu is a former railway station on the Tallinn-Pärnu line of the Estonian Railways.
In the period 1966-1970, the Architectural and Construction Department (now OPGS) of Lengiprotrans developed a project for an office building at Pärnu station.
Trust "Balttransstroy" is an organization of the USSR Ministry of Transport Construction, which carried out the construction of transport facilities on the territory of the Baltic republics and the Kaliningrad region. For construction, the trust used its own production facilities.
The production base of the Baltransstroy repair and construction department in Tallinn was built according to the Lengiprotrans project in 1971-1975.
The railway line Vilnius - Kaisiadoris is a section of the Lithuanian railways.
In the early 2010s, Lengiprotrans developed a project for the reconstruction of a double-track section Vilnius (excl.) - Kaisiadoris (inc.) For a speed of 160 km / h.
The railway line Petrasiunai (Pakruojis) - Radviliskis is a section of the Lithuanian railways.
In the Baltic republics of the USSR, narrow-gauge railways prevailed, which complicated their operation and increased the cost of transportation. In the 1980s, Lengiprotrans developed the re-seaming of such sections to a wide track of 1520 mm. In 1982, the Petrasiunai - Radviliskis section was put into operation.
The Kohtla-Järve and Ahtme gas shale plants are located in the northeastern part of Estonia.
The decision to build a new oil shale processing complex in Kohtla-Järve was made by the USSR State Security Committee in 1945. In the same year, Lentransproekt conducted an engineering-geological survey of sites for the construction of the Kohtla-Järve and Akhtme gas shale plants.
In 1948, the delivery of household gas produced from oil shale to Leningrad began. Later, the gas pipeline was directed to Tallinn and other cities in northern Estonia.
The railway line Pskov — Daugavpils — Vilnius is a section passing through the territory of Russia, Latvia and Lithuania.
The project of the second tracks on the site was developed by Lentransproekt (since 1951 — Lengiprotrans) in the late 1930s – early 1940s.
