NO. Depends what is printed on them. IF you hold a Bahncard (*railcard for DE) then it inclused 1 trip from station to destination (or reverse if from). This is also in about any major city in DE-no ''+PLUS" thus needed.
If there is stadtbahn on them-this means the shortened sector Westkreuz-Ostkreuz. But this summer there are big works on the line.
If there is B+station then its just till there.
There is also another variation which includes any S-bahn stop IN and on the ring=circle, forgotten what the name is for that.
in DDR times Stadtbahn meant indeed any stop on the S-bahn. But local fares on it were frozen at 20 Pf (MarkDDR), 10 eur-cents to official rate, 2 black market.
Since a few monthes, if you book without BC online, you mostly get offered a reduced dayticket to add-like bus+ in UK.
This is not entirely correct, there's
- Station grouping: Any ticket that has been issued to "BERLIN", including Sparpreis (Advance) fares, will include travel to any destination station within Zone A (including the Ringbahn) as well as Nöldnerplatz and Lichtenberg stations in Zone B.
Station grouping includes tickets from TVMs even if the station denomination is ambiguous ("Berlin (Berlin Alexanderpl.)" - see attachment this means that it was booked to Berlin Alexanderplatz, but still it is valid to any station in Berlin Zone A).
Station grouping does not apply if a minimum travel distance has not been included. It also does not apply to fare flows that are determined by the local Verkehrsverbund (passenger transport association) as these fares are often zonal fares with different regulations in place.
Station grouping only encompasses heavy rail travel, not light rail, tram or bus.
- City-Ticket: If a National (not International) ticket was bought with a BahnCard discount, the start and the destination may be printed with a "+City" suffix. It will generally allow one journey each before and after the rail journey, just like a single ticket of the local Verkehrsverbund, in buses, trams, light rail and local heavy rail (S/RB/RE/IRE, but not IC and ICE), within the borders of the city. (Exception: Berlin, where it is only valid in Zone A!)
- City Mobil: If a ticket has not been bought with a BahnCard discount, or City-Ticket is not included for another reason (insufficient minimum distance, International ticket, ticket for local rail), it is possible to book City Mobil that is similar to Plusbus in the UK. You will generally have the choice to book it as a single ticket or a day ticket. It is usually the same price as if you would buy it locally.
