For the records:
Line 10 is a line that was set up to replace the U4 subway line, which is closed due to construction works. The construction works (and operation of line 10) will last from Saturday, 23.03.2024 (4:00 a.m.) to Monday, 15.04.2024 (3:00 a.m.). Line 10 runs as follows: Westbahnhof - Hauptbahnhof - Old Town - Konstablerwache - Bornheim Mitte - Wittelsbacher Allee - Zoo. The loop at the Zoo is driven in the opposite direction (anticlockwise).
By the way, the U5 line is also closed during this period and is replaced by buses between Konstablerwache and Preungesheim.
