Weekday Absolute On-Time Performance: the percentage of the total number of on-time weekday trains divided into the total number of weekday trains scheduled to operate. An on-time train is defined as making all its scheduled station stops arriving at its destination terminal on-time, early, or no more than five minutes late. This indicator is a measure of service reliability.

Weekday Controllable On-Time Performance: the percentage of regularly scheduled trains arriving at the terminal no more than 5 minutes late, compared to the published schedule, excluding trains that are late due to incidents beyond NYCT's control, including sick customers, police or fire department activity, vandalism, opening of moveable bridges for maritime traffic and loss of outside electrical power. This indicator is a measure of service reliability.
