Swiss trains are famous for their punctuality and reliability. But from time to time, delays and cancellations can, and do, happen, inconveniencing thousands of passengers.
For instance, on Friday morning October 2nd, about half of the trains between Bern and Zurich were cancelled due to power outage, Swiss Federal Railways (SBB) said.
Problems such as this do occur occasionally, along with other impediments to a punctual service.
One of them, according to SBB, is the shortage of train mechanics in Switzerland, aggravated by training delays caused by the Covid-19 crisis.
As a result, some peak-hour trains could not be put back into service after the lockdown.
How can passengers know ahead of time about any last-minute cancellations or delays?
This link shows traffic disruptions expected until December 13th, the date when the new train schedule will go into effect.
The timetable is also constantly updated on the SBB Mobile app.
Any delays or last minute cancellations are indicated there in real time.
