The Broad Street line has been suspended between the Erie and Girard stations due to a medical emergency, SEPTA said in a social media post just after 4 p.m.
The transit agency said that shuttle buses will be available to transport between the two stations in both directions while the emergency is dealt with, SEPTA said.
The Broad Street line is still running in both directions elsewhere, the agency said.
No word yet on what the medical emergency is, but NBC10 is working to learn more.
