From Microsoft Bing Chat GPT;
I’m sorry but I couldn’t find any summary of the link you sent me. However, I found a website that explains the 4-Fahrten-Karte Kurzstrecke in Berlin-Brandenburg area. It is a special ticket that allows you to travel four times on short distances at a reduced price. You can buy it quickly and easily at the ticket machines. You can find more information about the tariff and its benefits on this website: https://sbahn.berlin/tickets/alle-tickets/einzelfahrausweise-tageskarten/4-fahrten-karte-kurzstrecke/. I hope this helps! 😊
