Immediately after the end of the Great Patriotic War, the Department of Plants of Lentransproekt (since 1951 - Lengiprotrans) developed a project for the reconstruction of a steam locomotive repair plant in Tallinn.
Rebuilding the car repair factories destroyed during the war was an urgent task on which the work of the entire railway transport depended. In this regard, design work began, as a rule, immediately after the liberation of the cities and was carried out at the restoration site by small expeditions made up of employees of the institute.
Simultaneously with the restoration, the projects provided for an extensive reconstruction of factories on the basis of modern technological processes and equipment at that time.
