PKP Branch of Mechanized Roadworks in Kraków was established in 1954 as a unit of Krakowska (later Południowa) Regional Directorate of State Railways.

The branch conducted repairs of tracks, subgrade and turnouts, using for this purpose high-performing equipment and machines of both national production and of production of reputable foreign companies: Matisa (Switzerland) and Plaser & Theurer (Austria).

Already in the 1970s, the then DOM owned three Trains for Mechanical Surface Works, Installation – Disassembly Base in Dębica and Base of Machines and Equipment in Kraków.

As of 1 April 1996 Dębica became the seat of a company. As a result of progressing reorganization of PKP on 1 July 1998 Infrastructure Repairs Plant in Dębica was created, which included the following executive units:

  • Section of Mechanical Surface Works with seat in Tarnów,
  • Section of Mechanical Maintenance Works with seat in Dębica,
  • Section of Mechanized Turnout Machines with seat in Dębica,

On 1 October 1974 PKP Branch of Mechanized Roadworks in Sucha Beskidzka was established. Its main task was to conduct capital works related to structure and subgrade engineering. Within the Branch operated three executive units, i.e. Management of Capital Works and Engineering Structures and Subgrade: Sucha Beskidzka, Tarnów and Rzeszów.

As a result of organizational changes in PKP road service on 1 January 1995 Bridge Branch based in Sucha Beskidzka was created. The main responsibility of the Branch was administration and maintenance of technical efficiency of railway engineering facilities.

For the purpose of implementation of tasks specified in the Organization Regulations of Bridge Branch at the area of South Regional Directorate of Koleje Państwowe, 6 Sections of Maintenance of Engineering Facilities were established in: Sucha Beskidzka, Bochnia, Krakow-Prokocim, Przeworsk, Zagórze and Nowy Sącz; Section of Mechanized Maintenance of Engineering Facilities in Sucha Beskidzka and Section of Diagnostics and Supervision of Engineering Facilities in Krakow-Prokocim.
