The Monthly On-Time Performance Report provides an analysis of train delays as reported for all Metra commuter rail lines. On-time is defined for this analysis as those regularly scheduled trains arriving at their last station stop less than six minutes behind schedule. Trains that are six minutes or more behind schedule, including annulled trains (trains that do not complete their scheduled runs), are regarded as late. “Extra” trains (trains that are added to handle special events but not shown in the regularly published timetables) are excluded from on-time performance calculations unless shown in the special-event schedules that include all intermediate station stop times and are distributed publicly via Metra’s website or on paper flyers. Cancelled (not annulled) trains and non-revenue trains are also excluded from on-time performance calculations.
