Vienna public transport report: punctuality and disruptions month by month
Since 29 October 2026, a collector of our own has compared the planned with the actual departure of Wiener Linien vehicles every 15 minutes at around 100 hubs. Every month is here with dated figures: share within two minutes of schedule, more than five minutes late, mean deviation, the most and least punctual lines, disruptions and their reasons, and what changed in the timetable.
In short: Since 29 October 2026, a collector of our own has compared the planned with the actual departure of Wiener Linien vehicles every 15 minutes at around 100 hubs. Every month is here with dated figures: share within two minutes of schedule, more than five minutes late, mean deviation, the most and least punctual lines, disruptions and their reasons, and what changed in the timetable.
A sample, not a full count: measured at the hubs in sammler-knoten.json, only full days count, and a line gets a rate only from 300 compared departures a month. "Punctual" means at most two minutes after schedule. The Wiener Linien publish one yearly figure for the whole network without a minute threshold; punctuality per line and month has not been open anywhere so far.
