It is a war love story made 50's or early 60's. A soldier falls in love with a women and I think she thought he was dead. At the end he finds her at the train station. I thought the name was something like purple heart. Can anyone help. One of the best movies ever.

I'm not sure if this version has a railroad scene in it, but other versions do.
