What is Hanau (I assume another train station) and how far is it from the Frankfurt Hbf?
Hanau is another town outside of Frankfurt. You might make the train, but 10 min. is rather tight. The Frankfurt train station is fun to roam around, lots of stores and places to eat, both upstairs and downstairs. Make sure you go outside and look at it from that viewpoint as it is really pretty, but massive. They just finished the renovation not too long ago.
