For many years, Lengiprotrans has been developing a general scheme for the development of the St. Petersburg (formerly Leningrad) railway junction. In the 1950s, the institute developed a general layout of the site for a 15-year perspective (1950-1965).
In accordance with the general scheme, the long-distance and suburban train traffic was transferred to diesel and electric traction.
During this period, the sections were electrified:
• Leningrad - Zelenogorsk - Roshchino (1951-1954);
• Leningrad - Sestroretsk - Beloostrov (1952);
Since the middle of the last century, Lengiprotrans has been developing a general scheme for the development of the St. Petersburg (formerly Leningrad) railway junction. In the 1960-1970s, the institute developed a general layout of the unit for the estimated 1980-1985 with a forecast up to 2000. On February 5, 1970, the junction layout was approved by the Ministry of Railways.
The Perm railway junction is a transit junction of the Perm branch of the Sverdlovsk railway, providing transportation of goods and passengers.
In 1935 Lentransproekt (since 1951 - Lengiprotrans) developed the general scheme of the Perm junction in connection with the increase in its traffic density. In 1937, a project was drawn up for the western sorting station of the junction.
The general scheme for the development of the railway junction of St. Petersburg and the Leningrad Region was developed by Lengiprotans in 2014.
Small (Children's) October Railway (MOZhD) is designed to educate and train schoolchildren and students for railway professions.
The first MOZhD in Leningrad was opened in 1948. It was 8.1 km of track and included 3 stations (Kirovskaya, Zoo, Ozernaya). In this form, the road existed until 1964. Subsequently, the line was shortened, and by the 1990s it was only 2 km.
Bronka port (multifunctional marine transshipment complex Bronka, MMTC Bronka) is located on the coast of the Gulf of Finland South of Kronstadt in the zone of the protective dam. The project for the development of railway approaches to the MMTC Bronka, developed by Lengiprotrans, was the first stage of infrastructure reconstruction on the Rybatskoe — Preportovaya — Ligovo — Bronka section of the Oktyabrskaya Railway.
Tikhoretskaya is a Railway hub of the North-Caucasus Railway. In the 2010s, Lengiprotrans developed the reconstruction of the station within the framework of the project “Comprehensive reconstruction of railway section Kotelnikovo — Tikhoretskaya — Korenovsk — Timashevskaya — Krymskaya with a by-pass of the Krasnodar Hub of the North-Caucasus Railway”.
For the first time PJSC Lengiprotrans began to consider the development of railway approaches to the port of Ust-Luga in 1992, when he took part in the development of the General Scheme for the development of seaports on the shore of the Gulf of Finland in the Baltic Sea.
The impetus to large-scale construction was the active development of the port for the planned increase in cargo turnover to 180 million tons, of which 118 million tons will have to be delivered by rail.
In 2011, the Ust-Luga Company established that by 2013–2014 the port's freight through the railway component is planned to be within 60 million tons.
The main goal of the project was the development of technical solutions for the maintenance of terminals of ULTK (Ust-Luga Container Terminal), AJPK (Automobile and Rail Transshipment Complex), MPC Yug-2 (Multi-profile transshipment complex Yug- 2 "), warehouse logistics center.
