On-time performance is a measure of service quality and system reliability as Amtrak operates principally over host railroad tracks.
National Railroad Passenger Corporation (Amtrak) trips of up to 250 miles are considered on-time if they arrive less than 10 minutes beyond the scheduled arrival time; 251–350 miles, 15 minutes; 351–450 miles, 20 minutes; 451–550 miles, 25 minutes; and greater than 550 miles, 30 minutes.
Amtrak On-Time Performance | Jul-11 | Jul-12 |
---|---|---|
On-time performance (percent on-time) | 72.0 | 74.5 |
Difference from same month previous year* | -2.4 | 2.5 |
* Current month minus same month previous year. This is generally used in the case of bound numbers, such as proportions that cannot exceed 100%.
NOTES: The current value is compared to the value from the same period in the previous year to account for seasonality.
Data are for endpoint arrival delays.
