New schedules for SEPTA buses and metro lines are set to go into effect starting Sunday and Monday, as the mass transit provider takes the next step in its metro transition that’s intended to make the system simpler for riders to navigate, officials said. The transition effort began last year, when SEPTA implemented new names and designations for subway and trolley lines. With the upcoming schedule change, SEPTA officials said, the city’s metro lines will be unified into what the provider called “a single, easy-to-use network with new maps, signage, and communication.” “Nearly all bus lines are now indicated by numbers, and all Metro lines are identified by letters,” SEPTA said in a statement. “As part of this schedule change, SEPTA is removing the side-by-side references to old bus letters (except for Route K) and using the new numbers only.” Along with this change, the T and G trolleys will now be referred to by their metro names, officials said. As an example, officials said, the T1 trolley will instead say “13th St to 63rdMalvern/Overbrook” and not Route 10. New trolley signal system Also, on Monday, Feb. 23, 2026, the D1 and D2 trolleys will operate with a new “communications-based train control system,” SEPTA officials said, that is intended to “provide a higher level of safety utilizingradio communications between the vehicles and the signal system.” SEPTA said this new system will establish operating times between trolleys, enforce safe stopping distances and prevent trolleys from exceeding speed limits. Under this new system, officials said, SEPTA will still operate the same number of trolleys — about five per hour in both directions — but arrival and departure times have been changed to accommodate longer trip times. This effort, SEPTA said, is part of a two-decade effort to refresh rail signal systems, which includes the installation of Positive Train Control systems on SEPTA’s Regional Rail lines.
