The two line graphs illustrate the proportion of trains, which belong to a particular company, that were either delayed or cancelled between October and November in 2008. Overall, both of these figures witnessed significant fluctuations throughout the surveyed period. Additionally, while the largest percentage of train trips cancelled was in October, November witnessed the highest delay rates.
In the first week of October, about 20% of all trains did not run on time. This figure then had risen slightly by 10% in the next week before it fell rapidly to approximately 5% by the end of October. In contrast, more than half of all trains were late during the second week in November, which was then followed by a slight drop to 40% in the third week.
Starting at only 1% in the first week, the percentage of trains that were cancelled reached a peak of 7% in the second week; however, it later dropped back to the initial figure. Erratic behavior can be witnessed in the proportion of cancelled trains for the rest of the period, with about 4% of total trains being cancelled in the final week.
