[3] In June 1945, a commission from the Ministry of Communications arrived in Poznań[3] to determine Poland's needs for rolling stock as the country was rebuilding from wartime destruction.

Since these matters extended beyond the scope of the plant's production, on 1 September 1945, the office was separated from the company's structure and directly subordinated to the Tasko Rolling Stock Industry Union,[3] which had been established by ministerial decree on 5 June 1945.

In 1963, the industry standard BN-63/3500-03 expanded the previously used system for assigning construction types,[7] and the Poznań-based office was authorized to manage these designations.

From 1965 onward, some of these responsibilities were gradually transferred to factory offices, which started hiring engineers educated at domestic technical universities.

[4] By the 1970s, designing new rail vehicles had become increasingly difficult without a proper research base, scientific studies, and structural modeling.

[10] As a result, in 1971, Central Design Office of the Rolling Stock Industry initiated the construction of a laboratory, a research hall equipped with test stands, and a dedicated prototype department.

[5] Plans were made to transform the office into the Central Research and Design Center for the Rolling Stock Industry by the turn of 1972 and 1973.

[5] Efforts were made to create an independent research base enabling the testing of complete vehicles, their systems, components, and construction elements.

[3] That same year, due to martial law, the publication of Pojazdy Szynowe was halted, and in 1992, the center's employees started publishing their articles in the section by the same name in Przegląd Mechaniczny.

[21] On 1 April 2019, the Łukasiewicz Research Network [pl] was established, incorporating the Tabor Railway Vehicle Institute along with 37 other entities.

[31] The Tabor Railway Vehicle Institute was involved in: During the times of the Polish People's Republic, the institute developed a total of 281 railway vehicles, including 27 locomotives and motor cars, 43 passenger, baggage, postal, and heating cars, 205 freight wagons, and 6 trams.

[43][45] The Institute generated income from its core activities, which involved conducting scientific research and development work, adapting their results to practical needs, and implementing them in technical sciences.

[5] In September 1965, on the 20th anniversary of its establishment, the bureau employed 372 people, including 141 engineers, 38 technicians, 11 economists, and 8 specialists from other fields.
