A passenger waits on a SEPTA train platform at a commuter rail station in Philadelphia on Friday, July 30, 2021.
As SEPTA works toward a stated goal of making its system easier to use and simpler to navigate, riders will soon see new names and designations for subway and trolley lines -- which the mass transit provider has taken to calling its "metro lines" and its bus lines.
For example, if you're hoping to take the Broad Street Line to the stadiums for a Phillies game this summer, you might find yourself taking the "B" to South Philly.
Want to head to a summer concert at Penn's Landing? Hop off the "L" at 2nd Street and walk on over.

It's all part of, what SEPTA is calling, the metro transition.

During this transition, routes throughout the system will be renamed -- all bus lines will be indicated by numbers, and all metro lines will be identified by letters.
