Since the introduction of the Lahn-Eifel-Bahn, the former Lahntalexpress (RE 25) from Koblenz Hauptbahnhof to Gießen also runs under this name.
The departures from Giessen take place on odd hours at 16 minutes past the hour on Mondays to Saturdays between 7:16 and 21:16 and on Sundays between 9:16 and 21:16.
