- WKD launches a new timetable from Jan. 1 through June 28, with 10-minute peak service on its busiest section
- Operator warns of periodic disruptions in early 2026 as it replaces rails and track switches under a safety upgrade program
- Trains will terminate at Warszawa Zachodnia during Jan. 17–31 works at Warszawa Śródmieście WKD
Warsaw commuter rail operator Warszawska Kolej Dojazdowa (WKD) will roll out a new timetable on Jan. 1 that raises peak-hour service on its busiest section to every 10 minutes, the company said.
WKD said it will operate a normal weekday schedule on Jan. 2 and Jan. 5, two working days that fall between Poland’s New Year and Epiphany holidays. Regional Review
The update matters for riders who use WKD’s trains to get into central Warsaw from towns such as Grodzisk Mazowiecki and Milanówek, especially as offices and schools reopen after the holidays.
It also comes with a warning: WKD is continuing a track renewal program that will bring periodic special timetables and replacement buses in the first half of 2026, even as the operator keeps the base schedule in place through late June.
In a statement, WKD said the basic timetable in force since early autumn will remain the default from Jan. 1 through June 28, with weekday trains running on both tracks along the Grodzisk Mazowiecki Radońska–Warszawa Śródmieście WKD line.
On the Warszawa Śródmieście–Podkowa Leśna Główna section, trains will run every 10 minutes in the morning and afternoon peaks and every 15 minutes off-peak; on weekends and public holidays the interval will be 20 minutes, WKD said.
The operator said its KPO-backed safety project—covering rail replacement over about 19 km of double track and installation of 15 turnouts, or track switches—is driving the disruptions, with the nearest major works planned at Warszawa Śródmieście during Mazowieckie’s winter school break in the second half of January and all work due to finish by May 31.

KPO is Poland’s National Recovery and Resilience Plan, a funding program tied to the European Union’s post-pandemic recovery package.
WKD said that from Jan. 17 to Jan. 31, trains will start and end at Warszawa Zachodnia WKD (platform 1) while it replaces track switches at the Warszawa Śródmieście WKD station.
Trains between Grodzisk Mazowiecki and Warszawa Zachodnia will run every 35 minutes, and a shuttle between Milanówek Grudów and Podkowa Leśna Zachodnia will run every 70 minutes to connect with the mainline service, it said.
The operator also plans extra weekday trains between Grodzisk Mazowiecki and Komorów, plus a limited replacement bus service between Komorów and Pruszków PKP in the morning and afternoon peaks. WKD
Warszawa Zachodnia and Pruszków PKP are major interchange stations, which should allow passengers to transfer to other rail operators, including Warsaw’s SKM suburban trains and Koleje Mazowieckie regional services, or to city buses and trams.
Turnouts are mechanical track switches that steer trains from one track to another, and replacing them typically requires shutting sections of track or stations to traffic.
WKD’s line links the centre of Warsaw with western suburbs such as Komorów and Podkowa Leśna and with outer terminals at Grodzisk Mazowiecki and Milanówek.
WKD said it expects further staged restrictions later in the first half of 2026 as crews move along the line, with some phases limited to weekends and others extending into weekdays depending on the scope of work.
As it enters 2026, WKD has also highlighted its wider modernization effort, with board member Piotr Madej saying the company was “proud to be the first railway operator in Poland to do it” as it shifts to electricity sourced with renewable-energy guarantees of origin. WKD
The operator said it will publish detailed service changes ahead of each stage and urged passengers to check updates before traveling.
