The changes include improved weekday Market-Frankford Line service effective Monday morning (February 11). Beginning at 6:45 a.m., SEPTA will expand Market-Frankford Line peak hour service frequency from 69th Street Terminal and Frankford Transportation Center (FTC). From 69th Street Terminal peak hour service will now operate until 9 a.m. while peak hour service from FTC has been extended until 9:30 a.m. with trains operating every four minutes. In addition, SEPTA will enhance midday service with trains leaving every six minutes instead of every eight minutes.
On too much of the system service frequency is such that having to take one route is fine, but having to take two is a big pain in the ass. Upping the frequency on the subways, which are basically the backbones of the system, will help that. Midday frequency of every 6 minutes is pretty good.
