In the 1970s, the former Lengiprotans Plants Department developed a project for the Riga Mechanical Repair Plant.
The project provided for:
- Compressor station with a capacity of 40 cubic meters / min.
- Workshop for the repair of road construction machines with a production output of 1.5 million per year.
- Re-equipment of the covered crane trestle for assembly areas with the expectation of producing 120 mobile plastering stations and 40 concrete mixing plants per year.
In the 1980s, Lengiprotrans prepared a design for a washing and steaming station for servicing the Mazeikiai oil refinery at the Bugeniai station of the Lithuanian railway.
At the facility, the following were designed: external power supply, low voltage and outdoor lighting networks, a transformer substation, vacuum collection equipment for collecting light oil products.
In the 1960s, Lengiprotrans participated in the design of buildings and structures on the Latakia - Oronte and Kamyshli - Aleppo - Oronte railways under construction in the Syrian Arab Republic. In total, about 100 buildings were designed in Syria, of which one of the largest was the building of the administration of the Syrian Railways.
In the 1960s, Lengiportrans, together with specialists from the Baltic Railway, developed a scheme for traction service of trains with diesel locomotives. Taking into account this scheme, a diesel locomotive depot was designed and built and the locomotive economy was reorganized for diesel traction at the Daugavpils station. Communication devices, heating and water supply were installed at the site.
Kokchetav II (now Kokshetau II) is a railway station of the Kazakhstan railway in the Akmola region of Kazakhstan. Trains follow through it in the direction of the stations Zhanaturmys, Kzyl-Tu, Astana, Novoishimskaya.
In 1981 Lengiprotrans carried out design and survey work on the reconstruction of the diesel locomotive depot at the station.
In the 1950s-1960s, Lengiprotrans developed a project to adapt the locomotive depot at Riga station for diesel traction for train traffic in the direction of Shkirotava station.
Leningrad-Finlyandsky (now St. Petersburg-Finlyandsky) is a railway station of the October railway in St. Petersburg.
In the period 1950-1967, Lengiprotrans developed a project for the construction of a new motor car depot at the Leningrad-Finlyandsky station. The construction and reconstruction of multi-unit depots in Leningrad was carried out simultaneously with the electrification of suburban railway sections.
TCh-21 Volkhovstroy is a repair locomotive depot at the Volkhovstroy-I railway station in the Volkhov district of the Leningrad region.
In the 2000s, the locomotive depot was reconstructed under the Lengiprotrans project in order to repair the VL10, VL11, VL15 series electric locomotives and increase the enterprise's capacity.
The construction of the following objects was carried out under the project:
In the 1980s, during the development of the railway network of the Kazakh SSR, Lengiprotrans developed a project for a motor depot for the Kokchetavtransstroy Trust in Astana.
Tselinograd (now Astana) is a railway station of the Kazakhstan Railways in the capital of Kazakhstan, the city of Astana.
In the 1980s, the Lengiprotrans Department of Plants (now part of the OPGS) designed a car repair depot for freight cars at the station.
