The Esil - Arkalyk railway line was designed and built in the 1950s. The line carries out freight transportation of bauxite ore from Arkalyk.
The bridges department of Lengiprotrans on the line designed a new railway bridge across the Ishim River.
In 1950-1960, the electrification of the Oktyabrskaya railway, the Bologoye railway junction was carried out, the technical re-equipment of the depot was underway. During this period, Lengiprotrans developed a project for the Bushevets repair and mechanical plant in the village of Bushevets, Bologovsky district, Tver region. The enterprise was intended for the production of spare parts for excavators and road construction machines.
In the early 1980s, Lengiprotrans developed a project for a bridge over the Kura River on the Osmaly-Ali-Bayramli (now Shirvan) section of the Azerbaijan Railway.
The Kura is the largest river in Transcaucasia, originating in the Armenian Highlands and flowing into the Caspian Sea. It flows through the territory of three countries: Turkey, Georgia, Azerbaijan.

The department of bridges of Lentransproekt (since 1951 - Lengiprotrans) developed a project for the capital construction of a bridge over the Ishim river on the Karaganda railway in 1946.
The Karaganda road connected the regions of central Kazakhstan with the railway network, provided access to rich natural resources: coal of the Karaganda basin, copper deposits of Kounrad, Dzhezkazgan and Boschekul. The development of the productive forces that followed the construction of the highway turned the region into the largest industrial base of the USSR.
Tikhoretsk Mechanical Repair Plant (now Tikhoretsk Machine-Building Plant named after V.V. Vorovsky) was founded in 1899 at the Tikhoretskaya junction station of the North Caucasian Railway. It became the largest city-forming enterprise in the north-east of the Kuban.
The Bui depot is located at the station of the same name on the Northern Railway. It was formed as a locomotive depot in 1905.
In the 1960s, Lengiprotrans developed a project for the reconstruction of the depot in connection with the transfer to the locomotive type of traction. In 1968, the first electric locomotive departed from the Bui station.
In 1950-1970, the former Department of Lengiprotrans Plants participated in the design of facilities related to the post-war reconstruction of the railway 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 special enterprises.
During this period, at the Pechora station of the Northern Railway, the department developed projects for a diesel locomotive and car repair depot.
Diesel locomotive depot Dno (now Lokomotivnoe depot Dno) is located at the Dno junction station of the Oktyabrskaya railway. There are 2 main railway lines running through the station: Yaroslavl - Pskov and further to the Baltic States and St. Petersburg - Novosokolniki and further to Belarus.
