SEPTA has released a Concept Regional Rail Line Map as part of its ongoing network modernization and “Reimagining Regional Rail” initiatives.

SEPTA has published the concept to its maps page and included a link to a feedback form measuring public approval.

Highlights contain the inclusion of the high-frequency “Silver Line,” visible through the thick trunk that runs from Penn Medicine Station to Jenkintown-Wyncote.

The map brings back the simplified line pairings of the original S-Bahn concept that coincided with the opening of the Center City Commuter Connection (CCCC) back in 1984.

No word on how long the feedback form will be open.
