Obukhovo is a stopping point of the Oktyabrskaya railway, located within the boundaries of St. Petersburg. The bridge crossing connected the Frunzensky and Nevsky districts of the city and provided a safe passage over the railway tracks.
Railway line Bui - Svecha - a section of the Northern Railway. In the 1960s - 1970s Lengiprotrans developed a project for second tracks on this section.
In 1967-1969, geological surveys were carried out and a design assignment was drawn up. In 1971, the project was approved, and construction began, which was carried out in two stages.
"American" bridges - a group of 5 railway bridges across the Obvodny Canal on the Moscow direction of the Oktyabrskaya Railway (OZhD). The first bridges were built in the 1840s as part of the construction of the Nikolaev railway (now OZhD). They received the name "American" for their design.
The project of the overpass at the intersection of Pulkovskoye Highway with Dunaysky Prospekt in St. Petersburg was carried out as part of the targeted investment program for the construction of facilities for the 2018 FIFA World Cup.
In the 2000s, Lengiprotrans specialists developed a project for an overpass along Aleksandrovskaya Fermy Avenue through the tracks of the Oktyabrskaya Railway. The old overpass on this site was built back in the Tsarist era at the turn of the XIX-XX centuries, and in the late 1990s it was closed due to an emergency condition.
The construction of a new overpass provided a significant increase in traffic flows both between the neighboring Frunzensky and Nevsky districts of the city, and transit traffic flows following the Ring Road.
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);
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.
