Berlin Germany Tourist Information and Travel Guide
Commuter trains in Berlin are called S-Bahns (fast trains). They typically operate at or above grade.
Each S-Bahn line is assigned an identifier that include the letter "S" followed by a number (e.g. S1, S2). There are approximately 16 lines in total.
Five of the S-Bahn lines follow the same route through the city centre (i.e. from Westkruz Station to Ostkreuz Station).
Although the Berlin S-Bahn system is run by a separate company from the one that operates the main transit system, passengers can use the same ticket.
Please visit the official S-Bahn website for current information regarding routes, maps, tickets and fares.
