Railway line 8 Warszawa – Radom – Kielce – Kraków (modernisation)

Modernisation of 27 km with rebuilt platforms and track layout, design and build, for up to 160 km/h; 77 km of track and 101 switches were to be replaced (PLK, 2016). The signing release gives 462 million PLN and a duration of 20 months; a PLK release of February 2016 gives 460 million PLN. The line was originally due to be modernised by 2012. In December 2016 PLK planned to finish the whole investment in the third quarter of 2017; the date trains began using the finished stretch was not found, so the opened date is the day trains ran on two tracks along the whole Warszawa – Radom route (29 August 2021), and the stretch may have opened earlier. Passenger speeds on the modernised line Okęcie – Radom Główny rose to 160 km/h from 11 June 2023. The drawn centreline is 7% shorter than the sourced 27 km; the sourced length is kept.

Design and build for 19.3 km: two tracks from Czachówek Południowy to Warka, level crossings, and the Warka and Chynów stations. The planned completion date given at signing was November 2020. PLK later gave this lot and Warka – Radom together as over 645 million PLN net (10 March 2022). The date trains began using this stretch was not found; the opened date is the day trains ran on two tracks along the whole Warszawa – Radom route (29 August 2021), and the stretch may have opened earlier. The Warka Miasto stop opened on 13 March 2022. Part of phase II (LOTs A, B, F), see the funding entry on the Okęcie lot. The drawn centreline is within 2% of the sourced length.

Design and build including a second track between Warka and Radom, with traffic suspended for about half a year; construction was to take about 2.5 years after design. Two tracks ran from Warka to Dobieszyn from 14 March 2021 and along the whole route from 29 August 2021. Passenger speeds on the modernised line Okęcie – Radom Główny rose to 160 km/h from 11 June 2023. The report puts the whole Okęcie – Radom modernisation at about 1.8 billion PLN; PLK gave about 1.7 billion PLN in June 2023. Length is the difference of the Warka (km 56.444) and Radom Główny (km 102.944) chainages on pl.wikipedia; the drawn centreline is 46.5 km.

Design and build of two tasks: LOT-A1-1 Skarżysko-Kamienna – Łączna (km 142.820 to 161.810) and LOT-A1-2 Łączna (without the station) – Tumlin (km 161.810 to 175.001), excluding Tumlin station; part of the project "Prace na linii kolejowej nr 8 na odcinku Skarżysko-Kamienna – Kielce – Kozłów".

Passenger trains are to reach 120 km/h and freight 100 km/h; PLK states that speeds rise by the end of 2028. No construction start was found. The drawn centreline is 2% shorter than the km span.

Design and build of about 11 km on the Świętokrzyskie – Małopolskie border (LOT B2_2 and B3 of Sitkówka Nowiny – Kozłów), excluding Sędziszów station. Line speed rises from 110 to 140 km/h (160 km/h beyond the Kozłów exit head), freight from 80 to 120 km/h. The tender was launched on 4 January 2023; 13 bids were opened on 31 July 2023. According to the schedule the modernisation is to end in June 2027; PLK (16 April 2025) gives "over 300 million PLN" for the 11 km, with the Kozłów station and the Klimontów stop, ready in 2027.
