New timetables coming soon should be more accurate — a result of long-overdue technology that SEPTA finished installing this year — thus commuters won't be left waiting for trains that are chronically behind schedule. Amtrak and SEPTA also tout increased coordination in the past year to address conflicts that have contributed to delays. Still, sharing the tracks on four routes is perhaps the thorniest challenge to SEPTA's system-wide goal of 90 percent reliability. These are the routes that riders say are no better than a year ago — and overall, SEPTA's performance data shows these lines have remained just as late, or even later, in 2017 as in 2015.
