Joel, As I'm sure you know train travel in Germany and France is fast and efficient. You won't need to go to the Hauptbahnhof in Frankfurt, just follow the signs for the airport station in the arrivals hall at the airport.

All the information you need for the rail journey is at http://tinyurl.com/zx9zr This is the English language website for Dbahn - German Railways. If you have any problems getting to that page go to www.bahn.de and click on "Internat. Guests" at the top.

Price for your trip is listed at about 45 Euro one-way. It may be cheaper to get a bus (or a flight ??- depending on your international airfare structure) but it's hard to beat German railways for efficiency and reliability.

Hope this helps with the quick and accurate part of your request - I'm too old to help with the dirty bit!

Have a good trip. Michael Sydney, Australia
