Narva is a border railway station on the Tallinn - Narva line of the Estonian Railways. Regular trains go through it in the direction of St. Petersburg and Moscow.
In the late 1960s - 1970s, Lengiprotrans carried out design and survey work to reconstruct the station.
In 1968-1969, longitudinal and transverse profiles of the station's track development were developed. In 1971, the plan of the Narva station and a set of devices for organizing passenger traffic to the Estonian TPP were designed.
Tallinn-Kopli - marshalling yard on the Keila-Tallinn line of the Estonian Railways.
The development and reconstruction of the station was designed by Lengiprotrans in 1956-1970.
Riga-Precu II is a railway station on the Riga-Ergli line in Latvia. Here, work is carried out with freight trains and long-term storage wagons.
In Soviet times, the station was equipped to organize centralized deliveries of goods to warehouses. In the period 1981-1985, Lengiprotrans designed the following facilities at the station:
• overhaul of the internal hangar warehouse system: hangar warehouse building and fire-fighting water supply pumping station;
• cargo yard for 3 million tons per year.
Riga Sea Port is a large port and oil product transshipment center on the Baltic Sea in Latvia.
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 Riga was designed.
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.
Liepaja railway junction is a large junction in Latvia, through which cargo is transshipped from Liepaja seaport to the railway.
In June 1993, the management of the Latvian Railway (LZD) sent an invitation to Lengiprotrans to take part in an international competition for the design of railway facilities in Latvia. Institute projects were approved by the Latvian Railway and the Ventspils City Council. In the same period, a plan for the development of the Liepaja railway junction was developed with an estimated cargo turnover of 16.4 million tons.
In the 1980s, Lengiprotrans carried out design and survey work for the construction of a departure park at Vilnius-Sortirovochnaya station. Transverse and longitudinal profiles, leveling marks were prepared, curves were calculated.
Siauliai station is connected by suburban traffic with Mazeikiai, Radviliskis, Klaipeda, Panevezys, Rokiskis stations. Also, passenger trains on the directions Vilnius - Klaipeda, Vilnius - Siauliai and Siauliai - Kaunas pass through it.
In the postwar years, the main forces of Lengiprotrans were directed to the restoration of railway infrastructure throughout the country. In particular, the Siauliai railway junction of the Lithuanian Railway was reconstructed.
In the 1950s, Lengiprotrans developed a project for the development of the Sovetsk station in the Kaliningrad region. Longitudinal profiles, strengthening of the subgrade, track section and communication at the station were developed.
In 1970-1980, Lengiprotrans carried out design and survey work for the construction of a new marshalling yard in the Vilnius railway junction. Engineering and geological materials were prepared for the technical project.
