Bus, subway, trolley and rail riders are finding many of their trips slightly rescheduled as SEPTA issues new timetables this week and next.

Most bus, subway and trolley schedule changes took effect Sunday and Monday, and Regional Rail schedule changes will take effect this Sunday.

The most significant rail changes will reduce existing waits between evening rush-hour trains on the R-2/Warminster, R-5/Doylestown, and R-6/Norristown lines.
