In the early 1970s, Lengiprotrans developed a project for the Nevsky overpass, which became part of the Central Arc Highway in St. Petersburg. The overpass connected Slava Avenue with Ivanovskaya Street above the tracks of the St. Petersburg-Sortirovochny-Moskovsky station. This became a significant event for the city, since the construction made it possible to directly connect the Frunzensky and Nevsky districts.
In the early 2000s, Lengiprotrans developed a project for the electrification of intra-nodal connecting lines of the Saint-Petersburg railway hub in order to ensure the passage of routes to the port of St. Petersburg on electric traction, bypassing the St. Petersburg-Sortirovochny-Moskovsky station.
Based on the results of the project, the following works were completed:
- electrified on direct current sections: Predportovaya — Narvskaya — Novy Port (7.5 km), Navalochnaya — Volkovskaya — Tsvetochnaya — Novy Port (11.4 km);
At the end of the 1990s, Lengiprotrans developed a project for a motor car depot in St. Petersburg, intended for servicing and repairing the ER2T electric trains of the Moscow and Vitebsk directions and high-speed Sokol trains on the St. Petersburg-Moscow line.
The huge depot complex was designed and built in a short time. The work of the entire technological cycle of construction - design, examination, order and supply of equipment, construction and installation work - were carried out practically in parallel.
The Leningradsky railway station in Moscow was designed according to a single project with the Moskovsky railway station in St. Petersburg during the construction of the Nikolaev railway in the 19th century. In the 1960s – 1970s, Lengiprotrans developed design documentation for the reconstruction of the Leningradsky railway station. At the same time, the idea of a single architectural concept was preserved.
In the 1970s, Lengiprotrans developed a project for a modern building for the Rostov-Yaroslavsky railway station at the station of the same name on the Northern Railway.
A passenger building for 300 people, a luggage compartment, a canopy for boarding arriving passengers on public transport were designed in the station complex. On the first floor of the building there were a cash desk, waiting rooms, a buffet, a first-aid post, a police station, a post office, a duty room and restrooms. On the second floor there is a restaurant with utility rooms.
Vitebsky railway station in St. Petersburg is the oldest railway station in Russia. The first building was erected back in 1837 for the Tsarskoye Selo railway. The first passenger train departed from here on October 30 of the same year. The modern station building was built in 1904.
In the 2000s, in preparation for the celebration of the 300th anniversary of St. Petersburg, the specialists of Lengiprotrans developed a project for the overhaul of the Vitebsk railway station.
The Baltiysky railway station in St. Petersburg was built in the 1850s after the Eastern Station in Paris. A suburban direction passes through the station, connecting the city with such popular places as Peterhof, Oranienbaum, Gatchina. In 1970–1980 due to the closure of the Varshavsky railway station, the Baltiysky railway station took over trains on the Gatchina — Luga direction.
Station Petrozavodsk-Passazhirskiy is part of the Oktyabrskaya Railway (OZhD) and is located in the capital of the Republic of Karelia. In the post-war years, in accordance with the general development plan of the city in 1945, it was moved from Golikova Street closer to the center - to Lenin Avenue.
Finlyandsky railway station was built in 1870 for the railway connecting St. Petersburg with the Grand Duchy of Finland. During the years of the blockade, it was the only operating station: the "Road of Life" began here, and in 1943 the first train with food arrived along the "Road of Victory".
Moskovsky railway station in St. Petersburg was designed according to a single project with the Leningradsky railway station in Moscow during the construction of the Nikolaev railway in the 19th century. In 1950-1960s Lengiprotrans was the general designer of the reconstruction of both stations for the purpose of expansion and modernization.
