+German Transit displays upcoming public transportation departures for the selected station. Modalities include U-Bahn, S-Bahn, Tram (Straßenbahn), Bus, Regional Train, and ICE Trains.  The data is sourced from Verkehrsverbund Rhein-Neckar (VRN), however the user can select any station in Germany (and even some neighboring cities, e.g. Strasbourg).
