This is in Augsburg, Germany. You can find this exact photo (and plan your trip!) on the tram company's website. I tried to find the exact location, and based on the building in the background, my guess is that this is near Uniklinik Augsburg (a teaching hospital, I think). They also have a tram spot nearby ("Uniklinik BKH") that's served by line 2, so I'm pretty confident that it's right next to the hospital.
