Overview
- A faulty signal box in Düsseldorf-Rath stopped S6 services during the evening peak, leaving riders stuck at Kettwig and Werden.
- On-board announcements shifted from a promised through-service to an early turnback, reflecting uncertain guidance from staff.
- Travelers weighed costly rideshares or used replacement buses, while others detoured via Wuppertal-Vohwinkel on the S9 and RE4, turning a 45-minute trip into roughly three hours.
- On paper the line runs every 20 minutes in about 42 minutes, yet recent days brought overcrowding, cancellations and short turns since its December restart.
- Separate construction at the Kaiserberg interchange through February 6 has already rerouted traffic, with SEV via Mülheim/Duisburg and added S1 trains offering alternatives that remain crowded and delay-prone.
