In the 1980s, Lengiprotrans engineers designed various objects in the Baltics. Thus, by order of the Baltic Railway, Lengiprotrans has developed a project for a railway overpass across the Leningrad — Tallinn highway at the intersection with the connecting railway lines of the Ülemiste — Maardu section. As a result, an important intercity highway with heavy traffic was developed.
In the 1980s, Lengiprotrans engineers designed various objects in the Baltics. Thus, by order of the Baltic Railway, Lengiprotrans has developed a project for a railway overpass on the Vilnius — New Vilnia stretch. Thus, an important intercity highway with heavy traffic was developed.
In the 1980s, Lengiprotrans engineers designed various projects in the Baltics. One of them was the overpass at the intersection of the road to the Pribaltiyskaya GRES with the railways of the USSR Ministry of Railways. During the implementation of the project, level crossings were eliminated at one level of the railway and an important city highway with heavy traffic and pedestrian traffic. As a result, the size of the car traffic has increased and its safety has increased.
The project of a road bypass for Narva and Ivangorod with a bridge over the Narva River was developed by Lengiprotrans in the 1990s - early 2000s. During the implementation of the project, level crossings were eliminated at one level of the railway and an important city highway with heavy traffic and pedestrians. As a result, the size of car traffic has increased and its safety has increased.
"Lentransproekt" (since 1951 - "Lengiprotrans") worked on the design of many objects in Kazakhstan. So, by the mid-1950s, a project was developed for plumbing workshops in Akmolinsk (since 2019 - Nur-Sultan), where components for engineering networks were produced.
In the postwar years, Lentransproekt (since 1951 - Lengiprotrans) continued to work in Kazakhstan. In 1948-1955, the electrical interlocking of forty-nine turnouts was developed at the Bolshaya Mikhailovka railway station of the Tselinnaya railway. The main goals of the project are to ensure the safety of train traffic, increase the station's capacity, and reduce the number of switchmen. Devices for blowing points were designed and the construction of an EC post at the station.
In the postwar years, Lentransproekt (since 1951 - Lengiprotrans) actively developed new projects. One of them was the construction project of the Gomel Electrotechnical Plant for the production of signaling devices and components for railway transport in the Byelorussian SSR.
In the postwar years, Lentransproekt (since 1951 - Lengiprotrans) actively developed new projects. One of them was the project of the Gomel steam locomotive repair plant of the USSR Ministry of Railways of the Belarusian Railway. The project was prepared and implemented in order to carry out all types of repairs for passenger and freight cars, thus increasing the working fleet of cars and ensuring traffic safety during the operation of the car fleet.
"Lentransproekt" (since 1951 - "Lengiprotrans") worked on the design of many objects in Kazakhstan. In the post-war years, according to his project, production facilities were built for impregnation of sleepers before laying and installing rail links 12.5 m long.
In the post-war years, Lentransproekt (since 1951 - Lengiprotrans) actively developed projects to restore the USSR railway infrastructure. One of them was a project for the restoration and reconstruction of car repair shops at the Brest station of the Belarusian Railway. In the course of its implementation, all types of repairs were carried out for passenger and freight cars to increase the working fleet of cars, and traffic safety was ensured during the operation of the car fleet.
