Praha – Benešov – Tábor – České Budějovice railway (4th transit corridor, lines 221/220)

Upgrade of the existing line between the Vinohrady tunnels and Praha-Hostivař: the line was straightened over the former Vršovice marshalling yard and made four-track, with new Praha-Eden and Praha-Zahradní Město stops (Zahradní Město opened on 24 September 2021). Správa železnic's 2018 release gave completion as 10/2021; cs.wikipedia's section table gives 2021 for commissioning, so only the year is recorded. The signing date is from cs.wikipedia. The 6.7 km extent is as stated there; the drawn line starts at Praha-Vršovice station. The Hostivař station rebuild (2.2 km, 2014–2016) and the Vinohrady tunnels (planned 2028–2029) are not part of this lot.

Upgrade of the existing double-track line: the first section of the corridor rebuild, started in September 2005 behind Praha-Hostivař and finished in 2008. Track, sleepers and bed were replaced, with noise walls along the line. No contractor or contract price was found.

Upgrade of the existing double-track line ("Optimalizace tratě Benešov – Strančice"). The table gives construction 2007–2010, while another passage of the same article says the reconstruction beyond Strančice ran from 2008. No contractor or contract price was found.

Double-tracking and partial relocation of the existing line for 160 km/h, with five new tunnels (Votice 590 m, Olbramovice 480 m, Zahradnický 1044 m, Tomice I 324 m and Tomice II 252 m, 2.69 km in all). The section table gives construction from 2009 (another passage gives 15 March 2010), construction complete in 2012 and the whole project complete by the end of 2013, which is the year recorded as opening. No contractor or contract price was found.

New double-track alignment, almost entirely off the old single track and about 2 km shorter, with the Mezno (840 m) and Deboreč (660 m) tunnels, four viaducts and the new Červený Újezd u Votic station. The June 2018 release gives the project extent as 19.9 km; cs.wikipedia gives the new alignment as 17 km, which is recorded. Works began on 1 May 2018 (the release planned 03/2018–08/2021; the leaflet gives 05/2018–12/2023) and the speed target was raised from 160 to 200 km/h in late 2019. The old line closed on 2 April 2022; the new line opened on one track on 1 July 2022 and on both tracks on 1 September 2022. 200 km/h has been allowed since 31 August 2025. The cost is the total investment cost; the OHL ŽS contract price is not recorded (cs.wikipedia reports its bid as CZK 4.378 bn).

Double-tracking and partial relocation of the single-track line, with a 444 m double-track tunnel, the first in South Bohemia, and an eight-span viaduct 455 m long. The start (3/2013) and the 2 June 2016 completion release (stated completion 7/2016) are from Správa železnic; the release speaks of 12 km and the section table of 11.4 km, which is recorded. cs.wikipedia gives "stavebně 2015, kompletně 2016" for commissioning. Cost is the total estimated investment cost; the contract price is not recorded.

Double-tracking of the existing line, with 110 km/h for ordinary trains and 160 km/h for tilting trains, and a new Tábor-Čápův Dvůr stop. One passage describes the section as a two-year reconstruction completed on 15 September 2009, the table gives 2006 as the start, so only the year is recorded. No contractor or contract price was found.

New 8.8 km double-track relocation on a new alignment, partly alongside the D3 motorway, replacing the single-track line through Roudná (the route is 765 m shorter). It has the 370 m Zvěrotický tunnel, viaducts of 830 m and 263 m and two new stops, Myslkovice and Doubí u Tábora. The leaflet gives works as 09/2019–04/2023; the old line closed on 2 September 2022. The design speed was raised from 160 to 200 km/h in 2020; 200 km/h has been allowed since 31 August 2025. The 4.8 bn cost is a press figure, not a contract price. The drawn length is 7.8 km against the 8.8 km stated.

Part of the Veselí nad Lužnicí – Doubí u Tábora modernisation (first stage, Veselí – Soběslav). Dates are years only, from the section table. The drawn length is 6.9 km against the 5.9 km stated. No contractor or contract price was found.

Upgrade of the existing line. Dates are years only, from the section table. No contractor or contract price was found.

Upgrade of the existing line (the Ševětín – Horusice project in the section table). Dates are years only. The table ends the section partway through Dynín station, so the drawn line, which runs to the station, is 3.8 km against 4.4 km. No contractor or contract price was found.

Track and station rebuild on the existing double-track line, with Dynín station reworked and the Neplachov stop moved ("Modernizace trati Nemanice I – Ševětín, 1. stavba, úpravy pro ETCS, 2. část"). The construction project runs from km 25.000, 2.8 km beyond Ševětín station, to km 29.303 at the end of the modernised Dynín – Horusice section: 4.3 km on koridory.cz, 4.0 km in the cs.wikipedia section table. The drawn line runs from Dynín station (km 29.0) to km 25.0, so Ševětín station to km 25.0 is not part of this lot (the planned Nemanice I – Ševětín project ends at km 25.0). Main works began in July 2018; the table gives completion in 01/2020. The contract value is from koridory.cz ("Podle smlouvy dosáhnou náklady stavby 597 486 627 Kč").

Planned double-track relocation on a new alignment, designed for 200 km/h with the Hosín (3 120 m) and Chotýčany (4 806 m) tunnels, the longest on the Czech network. The May 2024 leaflet gives almost 18 km, planned works 02/2026–12/2032 and no contractor selected; cs.wikipedia gives 21.5 km including stations and now plans 2028–2034. A PPP was planned in 2023 and dropped in 2025. The leaflet gives the official end of the project at km 25.0, beyond Ševětín station, where the Dynín – Ševětín lot begins. The drawn line follows only the OpenStreetMap proposed alignment, 12.3 km of the route; the stretches at both ends that join the existing stations are not drawn, so the drawn length is short of the stated 18 km. The existing single track between the two stations is not modelled as a lot.

Upgrade of the existing line into České Budějovice ("Modernizace trati České Budějovice – Nemanice I"). Built from February 2011 and completed in 2014. No contractor or contract price was found.
