What is the name of this movie?

I never got to catch the title of this movie but all I can remember from it is two people from different countries meet each other on a vacation and they end of robbing people for money and food and go to bars. And they are really in love. At the end of the movie they have to go their seperate ways and get back on the train. The movie pretty much just shows them two together staying alive with no money but depending on each other on love. It isn't Perfect Strangers which is about after WWI and the people were not married. Any clues? Anyone?
