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 1980s, Lengiprotrans developed a project for the production base for the construction and assembly train 675 of the Sevzaptransstroy trust in Tallinn.
At the facility, the following were designed: on-site heating networks, communication and power supply networks, reinforced concrete structures.
In the 1960s, Lengiprotrans developed a project for the reconstruction of the production base of the construction department No. 312 of the Balttranstroy trust in Kaliningrad.
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.
In the 1990s, Lengiprotrans developed a project for a workshop for the maintenance of passenger cars at the Kaliningrad station. A building with utilities was designed for technical inspection of Category 3 wagons.
