In 1950–1960, the electrification of the suburban sections of the Leningrad railway junction was widely carried out in accordance with the 1956 decree "On the general plan for the electrification of railways." During these years, the suburban line Lanskaya - Sestroretsk - Beloostrov was electrified under the Lengiprotrans project.
Later, in the process of introducing new achievements in the field of automation, telemechanics, communications and radio, a semi-automatic blocking with traffic light signaling was designed on the line.
TCh-1 Avtovo is a depot on the Kirovsko-Vyborgskaya line of the Petersburg metro. This is the first metro depot in St. Petersburg, opened in 1955.
In the 1970s, Lengiprotrans developed a project to expand the rolling stock base of the St. Petersburg metro depot at Avtovo station. The project provided for the development of complex power electrical equipment, internal electrical lighting, external power supply and electrical parts of other devices, many dozen industrial and other premises of a large metro depot.
In the 1970s, Lengiprotrans developed a project for electrical interlocking with mechanization of the hump at Ülemiste station of the Estonian Railways. The object contains 151 arrows, 2 beams of hump automatic centralization.
In the 1970s Lengiprotrans developed a project for electrical interlocking (EC) at Radviliskis station. A route-relay EC is installed at the station, the object includes 274 arrows.
In 1950-1970s one of the main directions of the Department of Plants (now as part of the Department of Industrial and Civil Buildings and Structures) of Lengiprotrans was the design of construction industry facilities and special enterprises. During this period, the institute developed a project for the building of an ice plant at the Kaliningrad station for the production of artificial ice.

In the 1970s, Lengiprotrans developed a project for route-relay electrical interlocking (EC) for 85 switches at Daugavpils II station.
In 1980-1990, Lengiprotrans developed a project for a boarding house on the shores of the Tsemesskaya Bay of the Black Sea in the village of Kabardinka, 15 km from Gelendzhik. The institution was intended for employees of the Leningrad (now Petersburg) metro.
In 1988, the recreation center "Kabardinka" received the first vacationers, employees of the subway, in wooden houses for 60 people. In subsequent years, according to the Lengiprotrans project, a boarding house for 300 people was built here.
In the 1990s, Lengiprotrans developed a project for carriage wheel workshops at Novosokolniki station of the Oktyabrskaya Railway. The enterprise carries out overhaul, medium and current repairs of wheelsets with replacement of elements.
In the 1950s – 1960s, along with the electrification of railway sections, Lengiprotrans designed a number of new multiple unit depots, including at the Leningrad-Tovarny-Vitebskiy station (now St. Petersburg-Tovarny-Vitebskiy).
Later, in the 1990s, the institute also developed a project for the reconstruction of the depot. Technical recommendations were prepared for strengthening the crane trestle in the procurement shop.
In the 1970s, the Lengiprotrans Plants Department (now part of the Industrial and Civil Buildings and Structures Department) carried out the design of locomotive and carriage facilities. During this period, specialists developed a project for a repair and equipment depot at the Arkhangelsk station of the Northern Railway.
