The regional breakdown reveals a dramatic reversal of fortunes. French-speaking Switzerland, often the subject of punctuality critiques, has staged a massive turnaround. Punctuality in Romandie soared to 93.4%, a sharp rise from 91.9% in 2024 and a distant cry from the 89.2% seen in 2023. Even more impressive is the connection reliability: a near-perfect 98.9% of passengers in the region made their connecting trains, surpassing the national average. SBB attributes this success to the improved "robustness" of the 2025 timetable.
However, the news is grim south of the Alps. Canton Ticino stands alone as the only region to suffer a performance drop, with punctuality sliding to 92.1%. The culprit? External chaos. Unreliable connections arriving from Italy, compounded by strikes and the ban on the Simplon line, forced a diversion of freight traffic onto the Gotthard axis. This created a bottleneck in the base tunnel, choking passenger lines and dragging down regional statistics. While the north hums with efficiency, the south remains vulnerable to cross-border volatility.
