SEPTA restored service on the Broad Street Line around 8:30 p.m., after protesters earlier blocked access to the subway station Democratic National Convention attendees expected to use for the evening's events.

For over three hours, southbound trains between Oregon Station and AT&T Station were open only to passengers with DNC credentials.

Protests were ongoing throughout the day, and about 4 p.m. more than 1,000 Bernie Sanders supporters faced off with police directly outside AT&T Station. When police asked them to move, some protesters instead sat on the sidewalk.

Democracy Spring, which has a platform of abolishing superdelegates, publicly funding elections and overturning Citizens United, organized many of the protesters and told them "If you want to be arrested, stay on the sidewalk. If you don't want to get arrested move to the street," said Desiree Kane, 34, of Denver, a spokesperson.

She complained they'd been greeted aggressively by police and escorted out of a rules committee session at the Convention Center earlier Monday. 

The Broad Street Line, which travels north-south through Philadelphia, is the major public transit route convention-goers could use to travel from Center City to Democratic National Convention events at the Wells Fargo Center. Passengers have been disembarking at Oregon Station and walking to the site of the convention about a mile away.
