SEPTA’s Metro transition is underway, and we’re progressing toward our goal of making our system easier to use and simpler to navigate for all of our riders. A key element of this process is streamlining the way we refer to our different services – all bus lines will be indicated by numbers, and all metro lines will be identified by letters. These changes have already begun appearing here on SEPTA’s web pages, and throughout 2025 you will begin seeing them in more places, including on our new schedules that will go into effect February 23 – 24. Note that this kind of transition takes time, and riders should expect to see both old and new language and signage used through the transition.
As a reminder, below is a summary of the changes that are occurring that can be used for your quick reference. For more complete information on the why, when and how we’re making these updates, please visit the Metro and New Bus Network sites.

These updates will continue to roll out through the year and will include in-person changes like new signage. If you haven’t already done so, we encourage all of our passengers to familiarize themselves with this nomenclature. We will reach a point where the new terminology is used exclusively, and we want to make this journey – like all your journeys on SEPTA service – as smooth as possible.
