As reported by dziennik.walbrzych.pl:

After a break of almost six months, Kulturzug—the “Train to Culture” operated by Deutsche Bahn—is returning to Lower Silesia’s railways. For yet another year, residents of Lower Silesia will have a direct and, it is worth adding, relatively inexpensive connection with Berlin.

This year, the route of the aforementioned train will change: it will travel through the City of Ceramics. Bolesławiec will therefore gain a direct connection with Berlin—and as early as mid-June!

The Wałbrzych-based outlet adds:

The good news is also that the Lower Silesian carrier has reached an agreement with its counterparts on the other sides of the Polish and German borders, and tickets for almost all cross-border connections operated by the Lower Silesian Railways will be available for purchase in the online system, regardless of which carrier operates them.
