Electric depot TCh-6 "Vyborgskoye" is located on the Moscow-Petrogradskaya line of the Petersburg metro, behind the station "Parnas".
The implementation of the project was scheduled back in 1984 with the aim of servicing the then planned area of new buildings in Shuvalovo. After the 1995 accident between the stations "Lesnaya" and "Ploshchad Muzhestva", the construction of the facility was carried out at an accelerated pace in order to unload the Nevskoye depot, which was forced to serve two lines.
Electric depot TCh-7 "Yuzhnoye" - a depot under construction on the Frunzensko-Primorskaya line of the St. Petersburg metro, behind the future station "Shushary". It will be the first metro depot built in St. Petersburg over the past 15 years, and one of the largest in Russia.
In the 1970s, Lengiprotrans developed a project for the Apatity railway junction in connection with the construction of an external railway transport for the Apatity mining and processing plant (GOK). The GOK mines apatite for the production of fertilizers and nepheline for the aluminum industry, processes ore at aluminum-nepheline-processing plants for concentrate production and further transportation. In the same period, a wagon preparation point was designed at the Apatity station.
Rzhev-II (Rzhev-Baltiysky) is a junction railway station of the October railway. In the 1970s, Lengiprotrans developed a project for the reconstruction of a locomotive depot for diesel traction at the station.
ТCH-8 Leningrad-Passenger-Moskovsky is an operational locomotive (formerly multiple-unit) depot at the St. Petersburg-Glavny railway station. The depot serves trains on the Moscow direction of the Oktyabrskaya Railway.
In the late 1970s, Lengiprotrans carried out design work for the reconstruction of the motor car depot. In 1977, the first stage of the repair and equipment depot was built at the Leningrad-Passenger-Moskovsky station.
In the 1990s, Lengiprotrans designed the St. Petersburg-Moskovsky Motor Wagon Depot at the Metallostroy station for maintenance and repair of electric trains.
In 2007–2009, the institute designed the reconstruction of the depot for servicing high-speed Sapsan trains intended for operation on the high-speed section of the St. Petersburg - Moscow - Nizhny Novgorod railway. The Sapsan trains that were being commissioned required a modern repair infrastructure, which could be provided through the reconstruction of the Metallostroy depot.
