Cologne in the dark: Power outage causes chaos in the KVB network!
On Wednesday morning there was a sudden power outage in Cologne, which affected many citizens and commuters in the south of Cologne. At around 8 a.m., a cable on Sechtemer Strasse, near Bonner Strasse, was damaged by an excavator during construction work. As a result, KVB lines 15, 16 and 17 went out of service for a period of time and numerous households in the Altstadt-Süd and Raderberg districts lost their power supply. At that time, traffic on Bonner Strasse was regulated by the police because the traffic lights weren't working either. The energy supplier Rheinenergie was initially unable to provide any information on the exact number of households affected. At 9:30 a.m. the technicians were finally able to give the all-clear, the power was restored and operations on the KVB lines gradually returned to normal.
How Review online reported that the failure led to significant disruptions in rail traffic. The trains stopped in particular between Chlodwigplatz and Ubierring. KVB line 15 only had to continue operations between Chorweiler and Eifelplatz, while line 16 only ran between Sebastianstrasse and Messe. Meanwhile, line 17 was completely closed. To help commuters out of trouble, replacement buses were set up.
Repair work and effects
The power outage not only had consequences for local public transport. Power was also out in various areas around the wholesale market, including Marktstrasse, Bonner Strasse and Alteburgerstrasse. Rheinenergie's work took a while, but by 9:30 a.m. the disruption was resolved and the normalized power supply was restored, which also resulted in a return to the usual traffic flow in the midday hours. This was a relief for the residents in Raderberg and the southern part of the city, who had previously been in the dark for a while.
