In the 1950s–1970s, the projects of the former Lengiprotrans Plant Department were related to the post-war restoration of the industry, the development of production capacities of transport facilities, the transfer of railways from steam traction to diesel locomotive, the development of construction industry facilities and the design of specialized enterprises.
In the 1980s, the Lengiprotrans Plants Department designed facilities on the new Obskaya — Bovanenkovo railway line. In particular, a locomotive depot was designed at the Obskaya station.
The Obskaya — Bovanenkovo line is the northernmost railway. The construction of the route was necessary to approach the gas fields on the Yamal Peninsula, the largest of which are Bovanenkovskoye and Kharasaveyskoye.
TCh-15 Leningrad-Baltiyskiy is a large multi-unit depot in St. Petersburg, founded in 1933. The depot was intended for lifting and periodic repairs, as well as technical inspection of sections.
In 1945-1946 Lentransproekt (since 1951 - Lengiprotrans) developed a project for the reconstruction of the depot. The electrification of suburban traffic in the Leningrad railway junction on the directions of Oranienbaum, Zelenogorsk, Pavlovsk and Gatchina required the construction of depot facilities for the repair and operation of electric rolling stock.
In the 1970s – 1980s, Lengiprotrans designed a railway station at Lodeynoye Pole station located on the Volkhovstroy - Petrozavodsk line of the Oktyabrskaya Railway. The station building is designed for 300 passengers.
In the period 1940-1960s, the specialists of Lengiprotrans designed the Mikun-Syktyvkar railway line, which connected the Syktyvkar terminal station with the Northern Railway. To serve passengers, the institute has also developed a project for a new railway station in the capital of the Komi Republic.
In 1964 the station was opened. It serves long-distance trains in the direction of Moscow, St. Petersburg, Pechora and Vorkuta.
Over the years, Lengiprotrans has been involved in the reconstruction of the Moscow railway station — from a large-scale reconstruction in the 1950s to preparations for meeting guests on the 300th anniversary of St. Petersburg. The building was built in the middle of the 19th century on the Nikolaevskaya railway according to a single project with the Leningradsky railway station in Moscow.
The Pechora railway station is located at the station of the Northern Railway. The settlement here was formed as a result of the construction of the North-Pechora railway, intended for the export of Vorkuta coal.
During the construction of the highway, the specialists of Lentransproekt (since 1951 - Lengiprotrans) also developed a project for a new station at the Pechora station.
The Novgorod railway station is located at the Novgorod-on-Volkhov station of the Oktyabrskaya railway.
The first wooden station was built in the 19th century on the line connecting Veliky Novgorod with the Nikolaev railway. During the Great Patriotic War, it was destroyed along with the railroad tracks. The project of the new station was developed by the specialist of Lentransproekt (since 1951 - Lengiprotrans), the famous Soviet architect Igor Yavein. The external appearance of the station embodied the collective image of the rich history and heritage of Veliky Novgorod.
The railway station at the Chernyakhovsk station (until 1946 - Insterburg) was built in 1860.
During the Second World War, the building was almost completely destroyed. Lentransproekt (since 1951 - Lengiprotrans) has developed a project for the restoration of the station.
Baltiysky railway station in Gatchina is located at the station of the Gatchina-Passenger-Baltic Oktyabrskaya railway.
Railway traffic from St. Petersburg to Gatchina was opened in 1872, and the Gatchina railway station was built the following year. However, due to the increased passenger traffic and inconvenient location, a new station building was built in 1889.
During the Great Patriotic War, the building was destroyed. In the 1950s, a new classical-style railway station was built according to the Lengiprotrans project.
