SEPTA's Broad Street Line, Market-Frankford Line and trolley routes will continue running 24 hours during the snow storm, officials said.
Regional rail and certain bus lines, which have been shut down, will make limited runs from 3 p.m. to about 10 p.m. today. The bus routes that will run are: 6, 14, 17, 21, 23, 52, 56, 59, 66 and 79.
The Streets Department this morning plowed major routes, which should be "generally passable," Streets Commissioner David Perri said.
Still, officials asked residents to stay off the roads, as crews prepare to work their way through smaller streets and deal with continuing precipitation.
