In the 1960s-1970s, Lengiprotrans developed a project for remote control of the fencing of trains at the Shkirotava station in Latvia.
Also at the station, the institute designed:
• adaptation of the locomotive depot for diesel traction;
• warehouse of spare parts and materials;
• pumping stations for pumping.
Bolshaya Mikhailovka - Zharyk is a section of the Kazakhstan railway.
In the 1980s, according to the Lengiprotrans project, the modernization of signaling devices on the railway section and the electrical interlocking of the Kalagir station by 33 switches were projected.
Tselinograd (now Astana) - Tobol is a section of the latitudinal South Siberian railway, passing through the territory of Kazakhstan.
The site was designed by Lentransproekt (since 1951 - Lengiprotrans) as part of the development of the Kartaly - Akmolinsk (now Astana) line in 1935-1945. The road was intended for the export of Karaganda coal along the shortest route to the South Urals.
In 1963, the institute developed a semi-automatic relay interlocking with traffic lights at the stations of the Tselinograd - Tobol section.
В ходе развития железнодорожной сети Казахской ССР «Ленгипротранс» разработал проект электрической централизации станции на 49 стрелок.
Ekibastuz II - station of the Kazakhstan railway in the area of a large coal deposit.
In 1970-1980, within the framework of the construction of railway approaches to the Ekibastuz industrial region, Lengiprotrans developed a project for the reconstruction of the station. In the period 1986-1990, the institute developed a project of electrical interlocking (EC) for 13 switches of the shunting area of the cleaning park at the Ekibastuz II station.
Baigul - Karazhal - a section of the Karaganda - Karazhal line of the Kazakhstan railway.
In the period 1986–1990 Lengiprotrans developed a project for electrical interlocking (EC) of 3 stations of the railway line with 46 turnouts.
This contributed to ensuring a high level of train traffic safety, increasing the station's throughput, strengthening power supply devices and improving the quality of personnel.
Bata - Karabas is a section of the Kazakhstan railway.
In the period 1986–1990 Lengiprotrans developed a project for electrical interlocking (EC) of 5 railway line stations with 21 turnouts.
This contributed to ensuring a high level of train traffic safety, increasing the station's throughput, strengthening power supply devices and improving the quality of personnel.
Tobol - Dzhetygara is a section of the Kostanay - Dzhetygara railway line of the Kazakhstan railway. The line was designed by Lengiprotrans in the 1950s to transport iron ores from the Sokolovo-Sarbayskoye deposit to the Magnitogorsk Iron and Steel Works.
In the postwar years, Lentransproekt (since 1951 - Lengiprotrans) developed a project for the restoration of the central boiler house at the Kaliningrad station.
Later, in 1970-1979, the institute carried out design and survey work to expand the boiler house. Laboratory analyzes were carried out, a well layout was prepared, and a chemical water purification unit was designed.
Keila is a railway station on the Tallinn - Keila - Riisipere line in the city of the same name in Estonia.
In 1963, Lengiprotrans prepared a project for a traction substation at Keila station. A master plan for Keila station was also developed.
The following objects were designed:
• construction part of the traction substation;
• foundations for equipment and fencing on the territory of the substation;
• Electricity of the net;
• water supply and sewerage, ventilation.
