In the 1990s, Lengiprotrans developed a project for the second main track on the Shipovka - Post section of 26 km in the Kaliningrad railway.
In the course of engineering surveys, mine workings were made, water wells were developed.
At the facility, the following were designed: a track complex, water supply, a railway bridge at picket 245, reconstruction of railway tracks at Shipovka station.
Kaliningrad-Passenger is a station of the Kaliningrad railway serving short and long-distance passenger trains.
In the 1960s, Lengiprotrans developed a project for an outfitting point for passenger cars at the station.
Based on the survey results, laboratory analyzes were carried out, columns and wells layouts, a cable route profile were developed. At the facility, water supply and sewerage networks, treatment facilities in the area of the repair and equipment depot were designed.
The feasibility study for the electrification of the Kuznechnoye - Khiytola - Kamennogorsk section was developed by Lengiprotrans in the 1990s.
Kartaly — Tobol is a railway section providing transport links between Russia and Kazakhstan.
Automatic blocking on the line was designed by Lengiprotrans in 1958 during the development of virgin fallow lands in Kazakhstan and adjacent territories.
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.
Molodechno - Vilnius - Kaliningrad - a section of the former Baltic railway, passing through the Byelorussian SSR, the Lithuanian SSR and the Kaliningrad region of the RSFSR.
In the 1960s, Lengiprotrans prepared a project for transferring the direction from locomotive traction to diesel traction.
Plans were developed for the territories of the following objects:
• Diesel depot of Vilnius station;
• steam locomotive depot of Vilnius and Kaunas stations;
• traction substation at Kaliningrad station;
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 1992-1994, Lengiprotrans, on the instructions of JSC Neftegaz, developed a feasibility study (FS) and working documentation for an access railway track to the export base of liquefied petroleum gases (LPG) on the Taman Peninsula on the Black Sea. However, the construction that had begun was suspended due to lack of funding.
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.
