NOTES: Data from 1998-2000 and 2001-2008 are not comparable due to a methodology change. Interruptions of service include major and minor mechanical failures. Since 2001, if the vehicle operator was able to fix the problem and return the vehicle to service without assistance, the incident has not been considered an interruption of service.
