Port of Klaipeda is the northernmost ice-free port on the Eastern coast of the Baltic Sea in Lithuania. It was a major transport center in the Soviet Union.
The Port of Riga is a large ice-free port in the capital of Latvia. Most of the cargo turnover is made up of transit cargo, the main of which are: coal, oil products, timber and container cargo.
In 1950-1960s Lengiprotrans developed a project for the railways of the Port of Riga. During the Soviet period, the ports of the Baltic Sea were important transit centers, in connection with which it was necessary to develop their transport infrastructure.
Locomotive depot Petrozavodsk (TCh-24) is located in the capital of the Republic of Karelia and is part of the Oktyabrskaya railway. It was founded back in 1916.
In 1959, a massive replacement of steam locomotives with diesel locomotives began on the Kirov railway. In this regard, in the late 1950s - early 1960s, Lengiprotrans developed a project for the reconstruction of the depot with a conversion to a heating system.
In 1962, the first repair of the locomotive was carried out at the locomotive depot in Petrozavodsk.
Station Tver (in 1931–1998 — station Kalinin) is a large transport hub of the Oktyabrskaya railway. The historic station was built in the middle of the 19th century. Since the 1970s, Lengiprotrans has been developing a project for a new station complex for 2,000 passengers.
In 1991, a new station was opened, located on the other side of the railway, opposite the old building.
Liepaja port is the largest ice-free port in Latvia. The seaport handles a large volume of various cargo: oil products, metal, timber, coal, chemical cargo, scrap metal.
In 1950-1960s "Lengiprotrans" developed the project of the railway lines of the Liepaja port. During the Soviet period, the ports of the Baltic Sea were important transit centers, in connection with which it was necessary to develop their transport infrastructure. The port in Liepaja was also significant as a naval base of the Baltic Fleet.
In the 1980s, Lengiprotrans designed the Urengoy - Nadym - Sovetsky highway. The road starts from the Urengoyskaya main compressor station (GCS) in the area of the city of Novy Urengoy and ends at the Komsomolskaya compressor station in the area of the Sovetsky village near the existing Ivdel - Ob'ye railway line of the Sverdlovsk railway. The motor road runs along the route of the Southern Corridor of the main gas pipelines and is intended for servicing compressor stations.
In 1950-1960s Lengiprotrans designed a bridge over the Abakan River as part of the construction of the Kyzyl - Mazhalyk (Aktovrak) - Abaza highway. The construction of the route made it possible to reduce the distance between the Aktovrak asbestos plant and the western regions of Tuva by more than 400 km.
The bridge was built on the Aktovrak - Abaza section on the territory of the Tyva Republic. The length of the bridge is 245 m.
In 1950-1960s Lengiprotrans designed the Kyzyl - Mazhalyk (Aktovrak) - Abaza highway. The road has republican significance and passes through the territory of Khakassia and Tuva.
The construction of the route made it possible to reduce the distance between the Aktovrak asbestos plant and the western regions of Tuva by more than 400 km.
In the 1990s, Lengiprotrans developed a project for the building of the Unified Dispatch Control Center (EDCU) of the Oktyabrskaya Railway in St. Petersburg. EDTSU is intended to accommodate dispatching personnel and a set of technical means associated with the operational management of transportation on the Oktyabrskaya railway.
The construction of the EDCU building became necessary to organize the receipt of operational and reliable information about the movement of trains, as well as to create modern working conditions for the dispatching personnel.
In the 1990s, Lengiprotrans developed a project for the electrification of the Volkhovstroy - Tikhvin - Koshta section in connection with the transfer of freight traffic to it. This was supposed to free the St. Petersburg - Moscow line for the development of high-speed passenger traffic.
