I live in Germany near Basel. There are some transit options here that cross the border, such as Tram 8; one end is in Weil am Rhein, Germany. There's also a bus line, Bus 38, that goes to Grenzach-Wyhlen in Germany.
It appears from everything I've read that EasyRide can only be used within the borders of Switzerland, and it cannot be used to take Tram 8 or Bus 38 beyond the Swiss border.
Is this correct?
