I don't have numbers per se, but I can say.... I worked at Via Rail here in the east coast, in the Atlantic. That train is notoriously late—many hours. Although I don't have data, I would agree that in the corridor region, delays of 10 to 12 hours are less rare than in the long service trains, but I would argue that they're certainly not isolated.
