PHILADELPHIA -- A man was shot and killed after an argument on the Walnut-Locust SEPTA platform in Center City on Saturday.

Riders in Philadelphia were looking for alternate routes while the subway was closed off.
"I can't get home now, I got to find another route to get home. They stopped the whole line," said Barry Askew from West Philadelphia.
"It's just ridiculous, it's always closed or you have to watch out because something is happening down there and it's scary how crazy it's getting," added Madison Burnite from South Jersey.
"I got to be more careful next time, especially during the day and weekends. More people take the subway and stuff," said Hoang Le from South Philadelphia.
People weren't surprised to learn of another incident happening on the subway, however, the timing of the shooting is what alarmed them.
"That's what I say to my parents, 'Oh, it's the daytime it's safe,'" said Burnite. "They're like, 'No, it's not safe.'"
The SEPTA platform reopened to riders at approximately 6:30 p.m.
