Correction: In 2026, the Deutschlandticket now costs €63 per month. While the ticket is designed for travel within Germany, you can technically use it to reach Prague, but not for the entire journey. The ticket covers all regional and local transport within Germany to the border. For Prague, the most common "pro" route is taking a regional train (RE) to the border town of Furth im Wald or Schöna. From those border points, you must purchase a separate ticket from the Czech Railways (České dráhy) for the remaining portion of the trip into Prague. Some specific cross-border regional buses or trains, like the "Trilex" services in the Saxony region, occasionally have special agreements where the German ticket is valid to the first station across the border, but Prague is too far inland for the German ticket to be valid for the whole trip. Always remember that the ticket is strictly for regional trains (RB, RE, S-Bahn) and is never valid on high-speed ICE or IC trains, even within Germany.
