Since the 1960s, Lengiprotrans has been actively involved in the development of the railway network in the Syrian Arab Republic. The main task was to connect the seaports of Tartus and Latakia with the eastern regions of the country for the export of goods. Before the start of these works, Syria had only one railway.
A number of railway projects have been developed in Syria. Later, in the 1980s, Lengiprotrans designed a diesel locomotive maintenance workshop with locomotive depot workshops at the Homs-II station.
In 1950-1960s Lengiprotrans developed a project for the reconstruction of a railway station in Riga. This was the first renovation of the building since its construction at the end of the 19th century on the Moscow-Vindavo-Rybinsk railway.
Lengiprotrans has done a lot of work on the reconstruction of the carriage facilities and, first of all, car repair depots (WRD). Among other objects, the WFD was designed at the Ekibastuz II station in the Kazakh SSR. Also, for this territory, a point was developed for the preparation of wagons for loading coal at the Ekibastuz coal basin - the largest coal deposit in Kazakhstan.
The production building, more than 500 m long, is equipped with special car-repair machines, which ensure fast and high-quality car repairs.
Throughout its entire activity, Lengiprotrans has taken care not only of production areas, but also of the well-being of its employees. In this regard, a number of projects for residential buildings were developed, including a project for a building at Moskovsky Prospekt, 145a.
5-storey building designed in the style of Stalinist neoclassicism. This object is located inside the quarter, in the immediate vicinity of the building of PJSC Lengiprotrans.
By order of the Ministry of Transport Construction of the USSR, Lengiprotrans designed the Chudovsky Reinforced Concrete Sleepers Plant (RCS). In the 1960-1970s, due to the growth of cargo transportation, the increase in the length and weight of trains, the used wooden sleepers began to be replaced by ZhBSh. The latter have a longer service life, provide uniform elasticity of the track along the length and stability in the ballast against shear.
Throughout its entire activity, Lengiprotrans has taken care not only of production areas, but also of the well-being of its employees. In this regard, a number of projects for residential buildings were developed, including a project for a 100-apartment building at 16 Varshavskaya Street. The Institute also built its own kindergarten at this address. The object is located in close proximity to the building of PJSC Lengiprotrans.
The rest house for locomotive crews (DOLB), built according to the project of PJSC Lengiprotrans, is located at the Luzhskaya-Sortirovochnaya station of the Oktyabrskaya railway, in the Kingiseppsky district of the Leningrad region. The facility was developed as part of the development of the public infrastructure of the Ust-Luga railway junction.
Since its inception, Lentransproekt (since 1951 - Lengiprotrans) has been involved in the transport development of the Kazakh SSR. First of all, the railways were intended for the development of virgin and fallow lands of the republic.
In 2002-2003, on the eve of the celebration of the 300th anniversary of St. Petersburg, Lengiprotrans performed large and important work on the design of buildings and structures in the western transport zone of the State Complex "Palace of Congresses" in Strelna.
In 1960-1970, Lengiprotrans developed a project for the reconstruction of the railway station in the city of Saratov, built in 1871.
