A 10-minute service interval ("headway") is operated between Lausen and Schönefeld from Monday to Friday during daytime service hours, and a 20-minute interval to Mockau. At other times Line 1E does not operate and 15-minute intervals are operated between Lausen and Mockau. Both services are worked mostly by three-car formations of Tatra stock ("Tatra-Großzüge", Tw+Tw+Bw). Some late evening and weekend services are worked by low-floor NGT8 stock. The primary function of these lines is to connect the densely populated Grünau-Süd, Schleußig and Schönefeld districts with the town center.
