Overview

• The Verkehrsinformationszentrale reported the tunnel was shut from about 6:00 on Tuesday with an expected reopening around 14:00.
• The transport administration’s press office declined to confirm a new personnel shortage on Tuesday, saying the reason is being clarified with the specialist unit.
• On Monday the tunnel was closed from roughly 6:15 to 14:00 after several security‑monitoring staff called in sick, which halted safety surveillance.
• Video monitoring of the tunnel normally requires six employees, according to the transport authority.
• The shutdowns produced queues on Heidestraße in Moabit and led BVG to suspend bus lines M41 and M85 between Hauptbahnhof and Potsdamer Platz.
