For SBB, train punctuality and connection punctuality are essential.

Train punctuality measures the percentage of all trains which are on time. A train is considered on time if it reaches its destination with less than three minutes’ delay.  Connection punctuality measures the percentage of connections reached. In this way, SBB takes into account the fact that some passengers miss connections when a train has less than three minutes’ delay and is still counted as on time.

Unfortunately, disruptions occur in our complex railway system despite all our best efforts and precautions. Even though these disruptions affect just a tiny fraction of journeys, several hundred travellers are affected almost every day. If commuters experience disruptions and long delays multiple times within a short space of time, it’s understandable that they may think this is due to a systematic problem. But, in the vast majority of cases, if disruptions affect the same line at similar times of day, it’s just a coincidence.

Every delay, cancellation and restriction is frustrating – not only for our customers, but also for us. We apologise for any inconvenience caused and thank you all for your understanding and patience. Please be assured that we are doing our best every day to offer quick solutions to our passengers experiencing disruptions.

Reliable, personalised information and the most accurate forecasts possible all play a key role. Our specialists work continuously to analyse the causes of disruptions and develop measures to resolve them.

As part of the "Open Data" strategy, the industry publishes numerous data, including train punctuality.
