Comprehensive works were carried out to strengthen the subgrade, a system of roads and two-level crossings was built, as well as 14 railway viaducts, 10 road viaducts and 9 pedestrian crossings. In addition, the platform infrastructure has been adapted to the needs of people with disabilities, and a new computer train traffic control system has been launched.

The contract was designed and built by the Metropolitan Railway, i.e. the revitalization of the Kokoszkowska Railway. A double-track railway line with a total length of about 17 km was built in a completely new route on the Gdańsk Wrzeszcz section to connect with line No. 2010. There are also 8 passenger stops with 15 single-edge platforms and one island platform.

As part of the contract, a local control center and a technical station were built, existing roads and pavements, parking lots in the “Park and Ride” system and bicycle parking lots were rebuilt. A total of 16 railway viaducts, 6 road viaducts, 5 passages under the tracks, 3 footbridges and 3 animal crossings were built. The contract also included the construction of a comprehensive drainage system and numerous environmental protection devices.” “The contract included the reconstruction of the track system of lines No. 91, 94, 603 and the construction of a new line 624 on two railway flyovers with a length of 541 and 612 m. In addition, 6 other engineering structures and two new passenger stops Kraków Zabłocie and Kraków Podgórze (Krzemionki) adapted to the needs of people with disabilities were built, along with platforms and accompanying infrastructure. The investment also included the reconstruction of the overhead contact line, gas and water supply networks, construction of traffic control equipment, power and teletechnical networks, lighting, rainwater and sanitary drainage.

As part of the contract, the accompanying road infrastructure was also rebuilt and new acoustic screens were installed.” “As part of the contract, in a consortium led by Budimex, the technical infrastructure of the station was designed, modernized and built, m.in. new turnouts and overhead contact line, as well as new computer traffic control equipment. The scope of work included, among m.in, works related to the construction of a new track surface with a subgrade and drainage system, demolition of the existing and construction of a new overhead contact line with a power supply system, and the construction of 12 new, very modern turnouts with a movable nose of the crossing, used on high-speed lines. In addition, the contract included the construction of a control room and the installation of a video monitoring system. After the modernization, the facility has been adapted to carry out train traffic at a speed of over 200 km/h.” “The contract implemented in the consortium included the modernization of LCS Kutno on the E-20 railway route. As part of the reconstruction, the tracks were dismantled, the subgrade was strengthened, a new surface was laid, and the overhead contact line and two signal boxes were built – in Kutno and Barłogi. A new computer traffic control system has been launched at the Kłodawa and Barłogi stations. On the completed sections of the E-20 line modernised as part of the project, traffic is carried out at a speed of 160 km/h for passenger trains and 120 km/h for freight trains.

The contract executed in cooperation with KZA Lublin included the construction and modernization of the track surface with the subgrade and drainage, the reconstruction of the overhead contact line with the subgrade and drainage, the reconstruction of the overhead contact line and power grid, the construction of new railway traffic control equipment, the reconstruction of the teletechnical networks and the control room, as well as the expansion of the hall of the emergency maintenance group of PKP PLK. A total of 44 new turnouts, 19 km of tracks and 25 km of overhead contact line were built at the Idzikowice station. The aim of the investment was to adapt one of the most important railway lines in Poland to the speed of 250 km/h. As part of the work, m.in were made. 4 km of new track surface on the Warszawa Zachodnia – Warszawa Gdańska section. During the implementation of the project, 4-passenger railway stops were modernized and rebuilt: Warszawa Zachodnia, platform No. 8, Warszawa Wola, Warszawa Koło, Warszawa Powązki and Warszawa Młynów, which are an interchange, connecting railways, trams and the station of the second metro line. The rebuilt stops have been equipped m.in. innovative lighting, facilities for people with disabilities, CCTV monitoring system and technological communication devices. In addition, the overhead contact line, power and teletechnical networks, railway traffic control equipment, as well as 3 railway viaducts and two footbridges were rebuilt. The works were carried out on three sections of the route: from Otwock to Pilawa, from Pilawa to Dęblin and from Dęblin to Nałęczów. The scope of works in the first part included the reconstruction of 74 km of track, Otwock, Celestynów and Pilawa stations, construction of 87 new turnouts, reconstruction of the overhead contact line, railway power networks and equipment, modernization of 12 railway crossings, reconstruction and construction of 22 engineering structures, two control rooms and the LCS building at the Pilawa station. In addition, 18 new platforms were built, sanitary infrastructure and water facilities were rebuilt. As part of the contract, 5 km of road systems were built.

As part of the contract, tracks 1 and 2 were rebuilt on the section from Pilawa to Dęblin. The scope of work included the modernization of 120 km of tracks with subgrade and drainage, reconstruction and construction of new infrastructure on 25 platforms adapted to the needs of people with disabilities at the following stations: Garwolin, Łaskarzew Towarowy, Sobolew, Życzyn and Dęblin, and the construction of 106 new turnouts. A comprehensive reconstruction of the overhead contact line and the network of railway power equipment was also carried out. The modernization additionally included 17 level crossings and the construction of 53 engineering structures. A three-span steel railway bridge with a length of 169.6 m was built at the Dęblin station. The works began with the reconstruction of track No. 2 – from the bridge over the Wieprz River to the Puławy Azoty station, along with tracks 2, 4, 6, 8 at the Zarzeka station and tracks 4 and 6 at the Puławy Azoty station. The length of the modernized section is 40 km. As part of the contract, about 83 km of tracks were rebuilt, including subgrade and drainage, as well as the Zarzeka, Puławy Azoty, Puławy Klementowice and Nałęczów stations. 98 new turnouts were also built, the overhead contact line and railway power networks and equipment were rebuilt. 23 engineering structures were built, 2 signal boxes at the Zarzeka and Puławy Azoty stations, 18 new platforms adapted to the needs of people with disabilities along with full infrastructure. In addition, about 20 km of road systems were built, and sanitary infrastructure, rainwater drainage network and teletechnical networks were rebuilt.
