Movie name. Last scene: a boy is leaving by train in Vienna

[george_har]

10 to 15 years ago, I've seen last 10 minutes of a movie. A boy and a girl (end of high school or university) have met (before the part I've seen), I assume while traveling in Europe. The boy is going to leave tomorrow back home to the US, a girl is staing in Europe for a while. I think she is not fromn the US, though. They spend their last night together in a park (in Vienna), and in the morniong the boy is leavin by train, saying something like "next year...". I will appreciate if you tell me the movie name. Thanks. George
