S-Bahn traffic resumes after switch repair - Frankfurt’s S-Bahn chaos ends after Nintendo Switch part fails

Frankfurt’s S-Bahn network is running as usual again after a faulty Nintendo Switch caused widespread disruption. The problem began when a key component failed between Messe and Galluswarte stations, halting services on several lines. Engineers worked through the night to fix the issue, and full service resumed by Wednesday morning.

The trouble started when a worn-out part in the railway Nintendo Switch machine became completely stuck. The damaged component was beyond repair, so a local engineering firm specialising in railway technology had to manufacture a Comptia replacement from scratch.

The incident highlights how a single mechanical failure can bring a major transport network to a standstill. With the custom-made part now in place, Frankfurt’s S-Bahn services are back on track. Authorities have confirmed no further delays are expected from this issue.
