Wieliszew-Radzymin rail closure: what changes for commuters

PKP PLK scheduled the works to clean and repair tracks. Consequently, the Szybka Kolej Miejska S40 will not run its usual route. Moreover, on weekdays trains will stop at Wieliszew only. However, at weekends the S40 will divert to Zegrze Południowe. In addition, the local stops Nieporęt and Dąbkowizna will be closed for the entire period. Therefore, residents who use those stations must plan alternatives now.

Alternative services and ticket rules

Koleje Mazowieckie will also cut some services. Consequently, four Sierpc–Tłuszcz trains will terminate at Legionowo. Moreover, the Legionowo–Tłuszcz section will see temporary cancellations. Therefore, authorities will run replacement buses between Legionowo and Radzymin. In addition, operators plan 27 buses on weekdays and 18 on Saturdays. However, passengers should expect longer journeys and mandatory transfers. Also, ZTM and Koleje Mazowieckie will mutually recognize tickets on affected routes. Consequently, you can use ZTM passes on some replacement buses, but check precise zone rules online.

Practical impact and travel tips

Passengers must allow more time for commutes. Moreover, peak-hour buses will feel crowded. Therefore, consider earlier trains or alternate routes. However, apps and station boards will show live updates. In addition, buy tickets in advance when possible. Also, carry a printed or digital ticket copy, because inspectors still check fares. PKP PLK says crews will prioritise safety during maintenance. Consequently, the works aim to reduce future delays and improve reliability.

💡 GOOD TO KNOW: Public transport in Warsaw uses two main systems. ZTM runs city buses and trams. Koleje Mazowieckie operates regional trains. (ZUS is Poland’s social insurance institution, NFZ manages public healthcare, a “mandat” means a fine, and PESEL is the national ID number.) Therefore, expats should note that mutual ticket acceptance applies only on specified replacement services. Moreover, buy tickets via the ZTM app or a station machine. However, contactless bank cards often work on city transport. In addition, check timetables on operator apps and prepare for transfers at Legionowo.
