České dráhy has warned passengers that track 171 between Prague Main Station and Beroun will close between 21:40 and midnight on both 11 and 12 December for scheduled modernisation. Long-distance EuroCity 363 “Bavorský expres” and regional R 748 “Berounka” will be partly replaced by buses, while several stopping services will terminate early at Karlštejn.
The Prague–Plzeň line is one of the busiest mixed-traffic corridors in Central Europe, linking Czechia’s capital with Bavaria’s manufacturing belt. While the works are timed to minimise daytime impact, late-evening business travellers connecting via Prague airport—or catching last-train links to Western Europe—should expect slower journeys and limited onboard services.

For mobility managers the key issue is missed hotel check-ins and overtime costs for drivers waiting at destination stations. ČD has published bus-stop maps and promised onboard Wi-Fi on the replacement coaches, but luggage space and bicycle carriage are restricted. Employers may wish to re-route staff via earlier departures or provide taxi allowances for the Prague–Beroun segment.
The closure is part of a multi-year upgrade that will eventually lift the corridor’s speed limit to 160 km/h and add ERTMS signalling—cutting Prague–Munich trip times to under 4 hours. In the interim, intermittent night works will continue through Q2 2026. Keeping expatriates informed is therefore essential to avoid travel-policy breaches and duty-of-care issues.
