Bad Nauheim
Bad Nauheim is now (2012) served by all Regionalbahn services on the Friedberg-Giessen route. The Mittelhessen-Express services as well as individual Regional-Express services on the Frankfurt Hauptbahnhof–Marburg route also stop in Bad Nauheim. However, Regional-Express services on the Frankfurt Hbf–Siegen route (the Main-Sieg-Express) and the Frankfurt–Kassel Hauptbahnhof route (the "Main-Weser-Express") and long-distance trains do not stop in Bad Nauheim. Morning and afternoon services operating as "RE-Sprinter" services of the "Main-Sieg-Express" (RE 99), which provide commuters with a fast connection to Frankfurt, stop in Bad Nauheim, but are the only services on the line to skip the neighbouring station of Friedberg.
