HOLIDAY SERVICE (Updated from December 17) Several Frontier routes will operate on a modified Sunday schedule on Christmas Day. The 93, 94, 96, 97, 98, 99, and 130 will operate every 2 hours instead of hourly. Also, neither the 112 nor 123 will not operate at all on Christmas. Center City to King of Prussia service will operate hourly between 6:00am and 6:00pm on the 125 via the S Gulph Rd routing; there will be no service along Henderson Rd via the 124 routing. On the railroad, the R1 Airport will operate its normal 30 minute headways; the R3 Elwyn and R8 Fox Chase will operate every 3 hours, with Fox Chase trains being through-routed to Elwyn and vice versa; the R7 Trenton will see hourly headways (mainly due to the NJT connections at Trenton); all other rail lines will operate every 2 hours. One extra train will be added to all Regional Rail lines, excluding the R1 Airport and R6 Cynwyd, during the 1:00am hour to accomodate New Year's Eve traffic. I would expect that the Market-Frankford El and Broad Street Lines will also have extended train service before Owl bus service kicks in.
